当我尝试不在我的css文件中使用浮动规则时,我最近遇到了问题。
当我的div元素的其他指定的css规则没有浮动时,我看到了问题。
任何人都可以告诉我,当我希望它开始一个“新行”而不是浮动时,我应该使用什么css规则而不是浮动?
示例:
.element1 {width:100%;float:left;margin:20px 0;}
.element2 {width:90%;margin:20px 0;}
如果我没有为element2
指定浮点数,它会忽略保证金声明。

使用清除属性。
.element2 {clear:both;} //options are: both, left, right
如果还不够,你可能需要在休息时添加一个div来'clearfix'。 看一下这种技巧:http://nicolasgallagher.com/micro-clearfix-hack/
/**
* For modern browsers
* 1. The space content is one way to avoid an Opera bug when the
* contenteditable attribute is included anywhere else in the document.
* Otherwise it causes space to appear at the top and bottom of elements
* that are clearfixed.
* 2. The use of `table` rather than `block` is only necessary if using
* `:before` to contain the top-margins of child elements.
*/
.cf:before,
.cf:after {
content: " "; /* 1 */
display: table; /* 2 */
}
.cf:after {
clear: both;
}
/**
* For IE 6/7 only
* Include this rule to trigger hasLayout and contain floats.
*/
.cf {
*zoom: 1;
}
你会像这样使用它:
<div class="element1"></div>//floats
<div class="cf"></div>
<div class="element2"></div>//new line, responds to margin, etc perfectly

clear:both
应该发挥魔力:
<强> CSS 强>:
.element1 {width:100%;float:left;margin:20px 0;}
.element2 {width:90%;margin:20px 0;}
.clear {clear:both;}
<强> HTML 强>:
<div class="element1">a</div>
<div class="clear"></div>
<div class="element2">b</div>
