1.概述

歡迎使用品優(yōu)購代碼規(guī)范, 這個(gè)是我借鑒京東前端代碼規(guī)范,組織的品優(yōu)購內(nèi)部規(guī)范。旨在增強(qiáng)團(tuán)隊(duì)開發(fā)協(xié)作、提高代碼質(zhì)量和打造開發(fā)基石的編碼規(guī)范,

以下規(guī)范是團(tuán)隊(duì)基本約定的內(nèi)容,必須嚴(yán)格遵循。

HTML規(guī)范

基于 W3C蘋果開發(fā)者 等官方文檔,并結(jié)合團(tuán)隊(duì)業(yè)務(wù)和開發(fā)過程中總結(jié)的規(guī)范約定,讓頁面HTML代碼更具語義性。

圖片規(guī)范

了解各種圖片格式特性,根據(jù)特性制定圖片規(guī)范,包括但不限于圖片的質(zhì)量約定、圖片引入方式、圖片合并處理等,旨在從圖片層面優(yōu)化頁面性能。

CSS規(guī)范

統(tǒng)一規(guī)范團(tuán)隊(duì) CSS 代碼書寫風(fēng)格和使用 CSS 預(yù)編譯語言語法風(fēng)格,提供常用媒體查詢語句和瀏覽器私有屬性引用,并從業(yè)務(wù)層面統(tǒng)一規(guī)范常用模塊的引用。

命名規(guī)范

目錄圖片HTML/CSS文件ClassName 的命名等層面約定規(guī)范團(tuán)隊(duì)的命名習(xí)慣,增強(qiáng)團(tuán)隊(duì)代碼的可讀性。

2. HTML 規(guī)范

DOCTYPE 聲明

HTML文件必須加上 DOCTYPE 聲明,并統(tǒng)一使用 HTML5 的文檔聲明:

<pre class="md-fences md-end-block" lang="html" contenteditable="false" cid="n22" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><!DOCTYPE html></pre>

HTML5標(biāo)準(zhǔn)模版

<pre class="md-fences md-end-block" lang="html" contenteditable="false" cid="n26" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><!DOCTYPE html>

頁面語言lang

推薦使用屬性值 cmn-Hans-CN(簡體, 中國大陸),但是考慮瀏覽器和操作系統(tǒng)的兼容性,目前仍然使用 zh-CN 屬性值

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n30" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
<html lang="zh-CN"></pre>

charset 字符集合

一般情況下統(tǒng)一使用 “UTF-8” 編碼

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n37" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
<meta charset="UTF-8"></pre>

由于歷史原因,有些業(yè)務(wù)可能會使用 “GBK” 編碼

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n40" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
<meta charset="GBK"></pre>

請盡量統(tǒng)一寫成標(biāo)準(zhǔn)的 “UTF-8”,不要寫成 “utf-8” 或 “utf8” 或 “UTF8”。根據(jù) IETF對UTF-8的定義,其編碼標(biāo)準(zhǔn)的寫法是 “UTF-8”;而 UTF8 或 utf8 的寫法只是出現(xiàn)在某些編程系統(tǒng)中,如 .NET framework 的類 System.Text.Encoding 中的一個(gè)屬性名就叫 UTF8。

書寫風(fēng)格

HTML代碼大小寫

HTML標(biāo)簽名、類名、標(biāo)簽屬性和大部分屬性值統(tǒng)一用小寫

推薦:

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n49" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
<div class="demo"></div></pre>

元素屬性

  • 元素屬性值使用雙引號語法

  • 元素屬性值可以寫上的都寫上

推薦:

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n72" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">

<input type=text>
<input type='text'>
<input type="radio" name="name" checked ></pre>

特殊字符引用

文本可以和字符引用混合出現(xiàn)。這種方法可以用來轉(zhuǎn)義在文本中不能合法出現(xiàn)的字符。

在 HTML 中不能使用小于號 “<” 和大于號 “>”特殊字符,瀏覽器會將它們作為標(biāo)簽解析,若要正確顯示,在 HTML 源代碼中使用字符實(shí)體

推薦:

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n83" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">

3. 圖片規(guī)范

內(nèi)容圖

內(nèi)容圖多以商品圖等照片類圖片形式存在,顏色較為豐富,文件體積較大

  • 優(yōu)先考慮 JPEG 格式,條件允許的話優(yōu)先考慮 WebP 格式

  • 盡量不使用PNG格式,PNG8 色位太低,PNG24 壓縮率低,文件體積大

  • PC平臺單張的圖片的大小不應(yīng)大于 200KB。

背景圖

背景圖多為圖標(biāo)等顏色比較簡單、文件體積不大、起修飾作用的圖片

  • PNG 與 GIF 格式,優(yōu)先考慮使用 PNG 格式,PNG格式允許更多的顏色并提供更好的壓縮率

  • 圖像顏色比較簡單的,如純色塊線條圖標(biāo),優(yōu)先考慮使用 PNG8 格式,避免不使用 JPEG 格式

  • 圖像顏色豐富而且圖片文件不太大的(40KB 以下)或有半透明效果的優(yōu)先考慮 PNG24 格式

  • 圖像顏色豐富而且文件比較大的(40KB - 200KB)優(yōu)先考慮 JPEG 格式

  • 條件允許的,優(yōu)先考慮 WebP 代替 PNG 和 JPEG 格式

4. CSS規(guī)范

代碼格式化

樣式書寫一般有兩種:一種是緊湊格式 (Compact)

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n145" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
.jdc{ display: block;width: 50px;}</pre>

一種是展開格式(Expanded)

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n148" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
.jdc {
display: block;
width: 50px;
}</pre>

團(tuán)隊(duì)約定

統(tǒng)一使用展開格式書寫樣式

代碼大小寫

樣式選擇器,屬性名,屬性值關(guān)鍵字全部使用小寫字母書寫,屬性字符串允許使用大小寫。

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n156" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
/* 推薦 */
.jdc{
display:block;
}

/* 不推薦 */
.JDC{
DISPLAY:BLOCK;
}</pre>

選擇器

  • 盡量少用通用選擇器 *

  • 不使用 ID 選擇器

  • 不使用無具體語義定義的標(biāo)簽選擇器

<pre class="md-fences md-end-block" lang="css" contenteditable="false" cid="n168" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">

代碼縮進(jìn)

統(tǒng)一使用四個(gè)空格進(jìn)行代碼縮進(jìn),使得各編輯器表現(xiàn)一致(各編輯器有相關(guān)配置)

<pre class="md-fences md-end-block" lang="" contenteditable="false" cid="n172" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
.jdc {
width: 100%;

<pre class="md-fences md-end-block" lang="css" contenteditable="false" cid="n229" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
/* 推薦 /
.jdc {
font-family: 'Hiragino Sans GB';
}

.jdc {
font-family: "Hiragino Sans GB";
}</pre>

屬性書寫順序

建議遵循以下順序:

  1. 布局定位屬性:display / position / float / clear / visibility / overflow(建議 display 第一個(gè)寫,畢竟關(guān)系到模式)

  2. 自身屬性:width / height / margin / padding / border / background

  3. 文本屬性:color / font / text-decoration / text-align / vertical-align / white- space / break-word

  4. 其他屬性(CSS3):content / cursor / border-radius / box-shadow / text-shadow / background:linear-gradient …

<pre class="md-fences md-end-block" lang="css" contenteditable="false" cid="n246" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">
.jdc {
display: block;
position: relative;
float: left;
width: 100px;
height: 100px;
margin: 0 10px;
padding: 20px 0;
font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif;
color: #333;
background: rgba(0,0,0,.5);
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
-o-border-radius: 10px;
-ms-border-radius: 10px;

命名規(guī)范

由歷史原因及個(gè)人習(xí)慣引起的 DOM 結(jié)構(gòu)、命名不統(tǒng)一,導(dǎo)致不同成員在維護(hù)同一頁面時(shí),效率低下,迭代、維護(hù)成本極高。

目錄命名

  • 項(xiàng)目文件夾:shoping

  • 樣式文件夾:css

  • 腳本文件夾:js

  • 樣式類圖片文件夾:img

  • 產(chǎn)品類圖片文件夾: upload

  • 字體類文件夾: fonts

ClassName命名

ClassName的命名應(yīng)該盡量精短、明確,必須以字母開頭命名,且全部字母為小寫,單詞之間統(tǒng)一使用下劃線 “_” 連接

.nav_top

常用命名推薦

注意:ad、banner、gg、guanggao 等有機(jī)會和廣告掛勾的不建議直接用來做ClassName,因?yàn)橛行g覽器插件(Chrome的廣告攔截插件等)會直接過濾這些類名,因此

<pre class="md-fences mock-cm md-end-block" lang="" contenteditable="false" cid="n280" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre-wrap; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><div class="ad"></div>

</pre>

這種廣告的英文或拼音類名不應(yīng)該出現(xiàn)

另外,敏感不和諧字眼也不應(yīng)該出現(xiàn),如:

<pre class="md-fences mock-cm md-end-block" lang="" contenteditable="false" cid="n285" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Consolas, "Liberation Mono", Courier, monospace; font-size: 0.9em; white-space: pre-wrap; text-align: left; break-inside: avoid; display: block; background-image: inherit; background-position: inherit; background-size: inherit; background-repeat: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(221, 221, 221); border-radius: 3px; padding: 8px 1em 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; color: rgb(51, 51, 51); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><div class="fuck"></div>
<div class="jer"></div>
<div class="sm"></div>
<div class="gcd"></div>
<div class="ass"></div>
<div class="KMT"></div>
...
