在Visual Studio Code中怎么使用CSSComb格式化CSS文件

這篇“在Visual Studio Code中怎么使用CSSComb格式化CSS文件”除了程序員外大部分人都不太理解，今天小編為了讓大家更加理解“在Visual Studio Code中怎么使用CSSComb格式化CSS文件”，給大家總結(jié)了以下內(nèi)容，具有一定借鑒價值，內(nèi)容詳細(xì)步驟清晰，細(xì)節(jié)處理妥當(dāng)，希望大家通過這篇文章有所收獲，下面讓我們一起來看看具體內(nèi)容吧。

Microsoft在2015年4月30日Build 開發(fā)者大會上正式宣布了 Visual Studio Code 項目：一個運(yùn)行于 Mac OS X、Windows和 Linux 之上的，針對于編寫現(xiàn)代 Web 和云應(yīng)用的跨平臺源代碼編輯器。

Visual Studio Code中使用CSSComb格式化CSS文件。

　　最近在使用Visual Studio Code，開始逐漸上手，發(fā)現(xiàn)非常好用。

　　不管是在JS文件還是在HTML文件中，右鍵點擊，都有“格式化文件”的菜單，幫助我們排版?？墒窃贑SS文件中，卻沒有這樣的選項。

　　在網(wǎng)上搜了一下，需要安裝一個插件，名字叫“CSSComb”，就是CSS的梳子啦，它不但可以排版CSS文件，還可以對樣式進(jìn)行排序。

　　一、安裝插件

　　在Visual Studio Code的左側(cè)工具欄中，最后一個工具就是擴(kuò)展，在搜索欄中輸入“csscomb”，就可以找到該插件并安裝了。

　　二、配置

　　在Visual Studio Code的“文件”->“首選項”->“設(shè)置”中，添加一行如下：

　　然后，在項目的根目錄下，添加一個文件，名為“.csscomb.json”，修改內(nèi)容如下：

　　現(xiàn)在，我們就可以對CSS文件排版了。
　　打開一個CSS文件，按“F1”，選擇“CSSComb: Format styles”，排版成功！

　　三、說明

　　幾個重要的參數(shù)說明一下：

    "always-semicolon": true, // 在每個樣式后面加“;”
    "block-indent": "  ", // 縮進(jìn)兩個空格
    "color-case": "lower",
    "color-shorthand": true,
    "element-case": "lower",
    "eof-newline": true,
    "leading-zero": false,
    "lines-between-rulesets": 1, // 每組規(guī)則后加一個空行
    "quotes": "single",
    "remove-empty-rulesets": true,
    "space-after-colon": " ",
    "space-after-combinator": " ",
    "space-after-opening-brace": "\n", // 在開始的{后換行
    "space-after-selector-delimiter": "\n",
    "space-before-closing-brace": "\n", // 在結(jié)束的}后換行
    "space-before-colon": "",
