修改 Markdown.here 基本渲染 CSS ，一键搞定微信公众平台文章编辑

和程序猿呆久了之后的一个表现就是：不想机械复制粘贴，如果能够搞几行代码，或者运行几个脚本，真是甚好。本文的部分方法，还是诸位程序猿教的O(∩_∩)O。

Why Markdown

首先，Markdown 大法好。

其次，因为想到大家在这里写文章都用 markdown，妹纸就想着，微信公众平台上的文章用 markdown格式是不是更有利于我们程序猿哥哥阅读呢（别夸我贴心?我是来求关注的

Next

打开 Chrome ，搜关键词：微信、markdown

万能的某乎上找到了这么一个话题「如何排版微信公众平台的文章？」。

下载了 Markdown.here 插件进行编辑测试。

测试报告

将文章复制到微信后台，快捷键 Ctrl+Alt+M，Markdown 格式就一键搞定了，赛高。但是针对手机端的屏幕，显示就出现以下问题：

1. 字体： 一级标题和正文文字都偏大 2 px

2. 代码颜色太单调：代码前加了高亮标识，但因没注明是 javascript/ruby or other languages，全部都是黑色的，阅读体验很不好

3. 类似于「值的类型 type」中 type 无法用红色标出来

所以一阵高兴之后妹纸的内心又奔溃了，本来就是为了偷懒找了插件，但出现上述问题之后，又要进行手动复制粘贴，不开森，于是又墨迹了一会儿，竟发现 Markdown.here 插件竟然可以修改。

插件修改路径： Chrome → 设置 → 扩展程序 → markdown.here → 选项 → 基本渲染 CSS

解决方式

问题1：字体大小

首先修改的是标题大小，分别将一级标题修改为 20 px；二级标题修改为 18 px

h1, h2, h3, h4, h5, h6 {
  margin: 1.3em 0 1em;
  padding: 0;
  font-weight: bold;
}

h1 {
  font-size: 20px;
  border-bottom: 1px solid #ddd;
}

h2 {
  font-size: 18px;
  border-bottom: 1px solid #eee;
}

h3 {
  font-size: 16px;
}

h4 {
  font-size: 16px;
}

h5 {
  font-size: 16px;
}

h6 {
  font-size: 16px;
  color: #777;
}

但是想到正文内容应该修改为 14 px；又在内容最后加了一句，当然这也是某位程序猿哥哥告诉我的：

p {
  font-size: 14px;
}；

一番修改之后，仍出现以下问题：

• 之后的文字，依旧是 16 px；

妹子又开始骚扰某涛程序员，得到的解决方法是在 li 后面加入 font-size ：

li {
  margin: 0.5em 0;
  font-size: 14px;
}；

终于完美解决了问题 1

问题2：语法高亮

接下来解决代码高亮问题，虽然选择了语法高亮的主题，但是复制到微信平台之后，全是黑色的，和小蚂蚁一样，代码阅读体验非常不好，改了几个主题之后，还是不行，内心有 1W 头草泥马奔过，后来在研究基本渲染 CSS 的时候，发现解决方案很简单：

在三个 ``` 之后加上 「javascript」或者「ruby」或者「其他语言」即可，原本黑色的代码，就会变成下图所示：

问题3：「值的类型 type」中 type 无法用红色标出来

这个问题研究了一天，终于被傻傻的我搞定了，直接在「基本渲染 CSS」中加上这一句即可

p code {
  color: rgb(217, 33, 66);
};

授人与鱼不如授人以渔，下图为诸位提供查找途径，这样子以后遇到类似的事情，就都可以轻松解决了~

路径：找到这一东西对应的元素，发现是在 p code中的 color，然后在 CSS 中添加语句。

有感而发

写了这么一大段教程，有些语法可能还不是很好= =，但却是让工作变得更便捷。
但其实最简单的解决途径是：找个程序员男票?

附

妹子其实还遇到一个问题，就是选择用空 4 格高亮代码的，在微信上生成 markdown 之后，代码是无法高亮的，请问这个该如何解决？需要加个判断么？

以下为「基本渲染 CSS」初始化内容

/*
 * NOTE:
 * - The use of browser-specific styles (-moz-, -webkit-) should be avoided.
 *   If used, they may not render correctly for people reading the email in
 *   a different browser than the one from which the email was sent.
 * - The use of state-dependent styles (like a:hover) don't work because they
 *   don't match at the time the styles are made explicit. (In email, styles
 *   must be explicitly applied to all elements -- stylesheets get stripped.)
