为什么小弟做出的版面这样...
而不是这样子呢？宽度应该没设定错呀...
回复讨论(解决方案)
.col1,.col2,.col3{ background-color:#efefef; width:31.3%px; float:left; margin:1%;}Copy after login
这里的宽度单位？想用百分比还是想用像素？
文字居中显示的话，可以再body中添加一个text-align:center;
也可以在每一个div元素中添加，这个属性会被所有的后代元素继承的。
?於 div class "article col1"和div class "col1" 差?在哪?... 因?小弟是??自?有些不懂得地方
?什?要?上要用div class "article col1" 意?差在哪?
