我怎样才能使按钮固定在顶部并将内容折叠到其中

Question

I tried this code but when i click on the button the content collapses and the button moves down. 我尝试了这段代码，但是当我单击按钮时，内容折叠并且按钮向下移动。 I want the content to collapse and the button remains at the top inline with the other button. 我希望内容折叠，并且该按钮与其他按钮保持在同一行的顶部。

Here is my HTML and CSS code: 这是我的HTML和CSS代码：

 #fixed { margin-top: 60px; } #block { border: solid #BDC3C7 1px; width: 360px; margin-left: 60px; display: inline-block; } .ab { margin: 5px; } #demo { max-width: 350px; color: blue; border: solid #ddd 1px; padding: 5px 12px 0px 12px; margin: 2px -10px 2px 0px; vertical-align: top; white-space: nowrap; font-size: 12px; text-align: left; font-family: Arial, Helvetica, sans-serif; } .list { list-style: none; border-bottom: solid 1px #eee } .as { margin: 0 0 10px 0; padding: 0; }

Give the blocks a vertical align rule. 给块一个垂直对齐规则。

Also never duplicate an html id. 也不要重复html id。 Use classes instead. 改用类。
