HomeWeb Front-endHTML Tutorialhtml页面内容超出后显示水平滚动条的问题 - 林七七

这个问题已经遇到好几次,解决起来也熟练了很多。
 
出现这种问题一般都是html或页面中的某一内部元素宽度超了。
下面总结我遇到的几种情况:
1、某一内部元素width设为100%,然而它还有border的宽度,border的宽度不包含在width中,所以结果超了。
2、span行内元素,由于它是行内元素,不设display:block之类,宽度设定对它没用,当初弄的时候没有意识到这个问题,结果在谷歌浏览器没出现问题,在IE中这个就暴露出来了,严重超出屏幕宽度,后来把span设为display:block;再设下它的宽度,问题就解决了。
PS:对设置width:100%的元素要注意它的border、margin、padding,小心超出屏幕范围。
 
对于寻找超出屏幕范围的内部元素,我一般先把页面分为几大板块来排除目标(即删掉某板块,看剩余版块是否导致出现水平滚动条,若还是出现,则证明该板块正常,否则该板块为我们寻找的目标板块——“罪魁祸首”),再继续在导致超出的版块中继续询查,直到找到该内部元素为止。
这样的方法挺笨的,希望大家分享自己的经验,交流下怎样能快速找到导致页面内容超出的内部元素,O(∩_∩)O谢谢。
