修改Mirages主题文章布局

关键点：修改了自适应中对主要文章内容的最大宽度。同时也把字号和代码的行高整一下，看起来更舒服，把下面的代码写入主题设置的自定义 HTML 元素拓展 - 标签: head 尾部 中

<style type="text/css" >
    #footer {
        font-size: 0.9rem;
        line-height: 30px;
    }

    .post-content,
    .post-content ul li{
        font-size: 1.2em !important;
    }

    .post-content code {
        font-size: 0.9em !important;
    }

    .comment-content pre code ul {
        font-size: 1.03em !important;
    }

    .post-content pre {
        line-height: 1.97em !important;
    }


    @media screen and (min-width: 768px) and (max-width: 1250px) {
        .container {
            max-width: 740px
        }
    }

    @media screen and (min-width: 1251px) and (max-width: 1599px) {
        .container {
            max-width: 985px;
        }

    }

    @media screen and (min-width: 1600px) and (max-width: 1799px) {
        .container {

        }
    }

    @media screen and (min-width: 1920px) and (max-width: 2399px) {

    @media screen and (min-width: 2400px) {

        }
    }

    @media screen and (min-width: 768px) and (max-width: 1301px) {

        body.content-lang-en .container {
            max-width: 900px
        }
    }
</style>
