🎨 Github 风格 Markdown 模板分享

笔者使用 Typora 编辑 Markdown 文件。然而 Typora 自带的 Github 模板与正宗的 Github 模板格式相去甚远，在行间距、段间距、字体、颜色等许多方面差异巨大，使得整个模板呈现出一种怪异、别扭的风格。为此，在 gpt 大人的帮助下，我自制了一份与 Github 极为接近的 Markdown 模板。

复制粘贴为 .css 文件，拖入 Typora 主题文件夹即可使用。

效果图如下：

:root {
    --side-bar-bg-color: #fafafa;
    --control-text-color: #777;
    --fgColor-default: #1f2328;
    --fgColor-muted: #59636e;
    --fgColor-accent: #0969da;
    --bgColor-default: #ffffff;
    --bgColor-muted: #f6f8fa;
    --borderColor-default: #d1d9e0;
    --borderColor-muted: #d1d9e0b3;
    --base-text-weight-semibold: 600;
    --base-size-16: 1rem;
    --base-size-24: 1.5rem;
    --base-size-40: 2.5rem;
    --fontStack-monospace: ui-monospace, SFMono-Regular, SF Mono, Menlo, Consolas, Liberation Mono, monospace;
}
