或者 ¡important! 更容易理解，只不过 !important 更容易解析，打起来也更方便。</p> </blockquote> <p style="padding-bottom:0px;border-right-width:0px;padding-left:0px;outline-width:0px;padding-right:0px;margin-bottom:1.62em;border-top-width:0px;border-bottom-width:0px;color:#373737;vertical-align:baseline;border-left-width:0px;font-weight:300;padding-top:0px;border-image:initial;">虽然这段解释很合理，但还是没法解决 !important 造成混淆的问题。改成 !unimportant 肯定更离谱了（除非你是用 <a style="padding-bottom:0px;border-right-width:0px;margin:0px;padding-left:0px;outline-width:0px;padding-right:0px;font-family:inherit;border-top-width:0px;border-bottom-width:0px;color:#1982d1;vertical-align:baseline;border-left-width:0px;text-decoration:none;padding-top:0px;border-image:initial;" href="/misc/goto?guid=4958339239976546743" rel=" noreferrer" target="_blank">More CSS</a>，谢谢 <a style="padding-bottom:0px;border-right-width:0px;margin:0px;padding-left:0px;outline-width:0px;padding-right:0px;font-family:inherit;border-top-width:0px;border-bottom-width:0px;color:#1982d1;vertical-align:baseline;border-left-width:0px;text-decoration:none;padding-top:0px;border-image:initial;" href="/misc/goto?guid=4958339240770351859" rel=" noreferrer" target="_blank">@Nemo_A</a> 告诉我这么有意思的东西，注意看页尾的 copyright 信息），<a style="padding-bottom:0px;border-right-width:0px;margin:0px;padding-left:0px;outline-width:0px;padding-right:0px;font-family:inherit;border-top-width:0px;border-bottom-width:0px;color:#1982d1;vertical-align:baseline;border-left-width:0px;text-decoration:none;padding-top:0px;border-image:initial;" href="/misc/goto?guid=4958339241562632944" rel=" noreferrer" target="_blank">有人提议</a>说把 !important 改成 !!important 就可以都说得通了，这想法太天才了，建议 More CSS 可以把这个建议纳入下一版。</p> <div style="padding-bottom:9px;border-right-width:0px;background-color:#eeeeee;margin:0.4em auto 1.62em;padding-left:9px;outline-width:0px;width:685px;padding-right:9px;max-width:96%;border-top-width:0px;border-bottom-width:0px;color:#373737;clear:both;vertical-align:baseline;border-left-width:0px;font-weight:300;padding-top:9px;border-image:initial;background-origin:initial;background-clip:initial;" class="wp-caption aligncenter"> <img style="border-bottom-color:#eeeeee;border-top-color:#eeeeee;margin:0px auto;display:block;max-width:98%;border-right-color:#eeeeee;border-left-color:#eeeeee;" class=" " title="戳中笑点的愚人节玩笑" alt="从 !important 到关于叹号的 !一切" src="https://simg.open-open.com/show/807a6f0176c37648c05fa692cc60fb2f.png" width="675" height="220" /> <p style="position:relative;padding-bottom:5px;border-right-width:0px;padding-left:40px;outline-width:0px;padding-right:0px;font-family:Georgia, serif;margin-bottom:0.6em;border-top-width:0px;border-bottom-width:0px;color:#666666;font-size:12px;vertical-align:baseline;border-left-width:0px;padding-top:10px;border-image:initial;" class="wp-caption-text">More CSS 的 !unimportant 用法</p> </div> <p style="padding-bottom:0px;border-right-width:0px;padding-left:0px;outline-width:0px;padding-right:0px;margin-bottom:1.62em;border-top-width:0px;border-bottom-width:0px;color:#373737;vertical-align:baseline;border-left-width:0px;font-weight:300;padding-top:0px;border-image:initial;"><span style="padding-bottom:0px;border-right-width:0px;margin:0px;padding-left:0px;outline-width:0px;padding-right:0px;font-family:inherit;border-top-width:0px;border-bottom-width:0px;color:#339966;vertical-align:baseline;border-left-width:0px;padding-top:0px;border-image:initial;">// 我不知道怎么过渡了。请大家把这里想像成自然和谐的过渡语句。</span></p> <p style="padding-bottom:0px;border-right-width:0px;padding-left:0px;outline-width:0px;padding-right:0px;margin-bottom:1.62em;border-top-width:0px;border-bottom-width:0px;color:#373737;vertical-align:baseline;border-left-width:0px;font-weight:300;padding-top:0px;border-image:initial;">带 着开始的那些感叹开始寻找叹号表示 not 的起源，从亚里士多德到布尔到丹尼斯里奇，都没什么有趣的发现。但是考据的乐趣并不是找到问题的终极答案，而是过程中发现的各种花边消息（这其实是一直以 来在没有找到答案的时候为了安慰自己说的话）。叹号的故事还是蛮有意思的。</p> <h2 style="padding-bottom:0px;border-right-width:0px;margin:0px 0px 0.81em;padding-left:0px;outline-width:0px;padding-right:0px;border-top-width:0px;border-bottom-width:0px;clear:both;font-size:15px;vertical-align:baseline;border-left-width:0px;padding-top:0px;border-image:initial;">关于叹号的 !一切</h2> <ul style="padding-bottom:0px;border-right-width:0px;list-style-type:square;margin:0px 0px 1.62em 2.5em;padding-left:0px;outline-width:0px;padding-right:0px;border-top-width:0px;border-bottom-width:0px;color:#373737;vertical-align:baseline;border-left-width:0px;font-weight:300;padding-top:0px;border-image:initial;"> <li style="padding-bottom:0px;border-right-width:0px;margin:0px;padding-left:0px;outline-width:0px;padding-right:0px;font-family:inherit;border-top-width:0px;border-bottom-width:0px;vertical-align:baseline;border-left-width:0px;padding-top:0px;border-image:initial;">!
