如图，粉红色与绿色的行高对不齐，请问如何才能自动对齐呢？

楼主参考下

自己慢慢设置，设一个值调了看看、、不等在重新设

#sidebar { float:left; padding:auto; width:445px; background:#F0F; height:540px; overflow:hidden; }

#content { FLOAT: left; width:650px; PADDING:auto; background:#499; height:540px;overflow:hidden; }

改成这样试试一下，因为都是内部的DIV，不属于浮动层，DIV会随着数据的增加变高，很明显，你左右2部分的P标签不一样多，建议设置成固定值，然后overflow:hidden;这样垂直方向就不会被挤开。
