在任何地方找不到解决方案(我猜这一定是一个非常常见的问题).

我正在创建一个带侧边栏的响应式设计,其中侧边栏需要具有200px的固定宽度并且具有未知高度.我怎样才能使主要内容区占据所有剩余的宽度,而不会有任何不当行为.

最接近我的是以下内容,但问题在于侧边栏可以与页脚重叠.任何人都可以建议修复我的代码,或与我分享一些有效的代码？

* {

padding: 0;

margin: 0;

/* change this to "right: 0;" if you want the aside on the right. Also, change the "margin-left" code, below. */

left: 0;

padding-top: 20px;

padding-bottom: 20px;

padding-left: 10px; /* If you change this value, remember to change the margin-left value of #primary */

padding-right: 10px; /* ditto */

}

#primary {

background: red;

/* change this to margin-right if you want the aside on the right. Also change the "left" code, above. */

margin-left: 220px; /* aside_width + aside_left_padding + aside_right_padding = 200px + 10px + 10px */

padding: 1em; /* whatever */

}

#footer {
