This example uses JS script to control the height of parallel DIVs. Usually in DIV layout, adaptive height has always been a headache. Generally, background images, outer DIVs, right columns covering the left columns, etc. are used to solve the problem. . Now after adding the script, it is much simpler. If there are three horizontally parallel DIVs, fbox, mbox, and sbox, just write in the tag: onload="P7_equalCols('fbox','mbox','sbox ')", test conditions: ie5.x, ie6.0, FF1.03, NS7.2, opera8.01. Final effect.

如果设计者使用像素为单位指定文字大小，大多数的用户将无法缩放文字，因为 Internet Explorer 改变文字大小的方式与别的浏览器不同。Mozilla 和 Opera 可以缩放已经设定像素大小的文字，而Windows 下的IE却不能。
