我总是试图在屏幕底部保留一个div.并且由于div宽度小于屏幕所以它应该位于屏幕的中间.第一件事是工作,但如果总是左边漂浮.
代码是
<div id="catfish" style="position:fixed; bottom:0; z-index:5000; width: 468px; margin: 0px auto;">
<div style="position:absolute; margin-bottom:0px; z-index:15;">
<a href="Javascript:void(0);" onclick="document.getElementById('catfish').style.display='none'"><img src="http://secretdiarybd.com/wp-content/uploads/2015/05/close.gif.png" alt="close" height="20"></img></a>
</div>
<div>
Some elemnt here
</div>
</div>

jsfiddle的例子 请帮帮我.
您必须添加left并right与值0.您的DIV如果你也想在中间的文本必须添加text-align: center;
<div id="catfish" style="position:fixed; bottom:0; left:0; right:0; text-align:center; z-index:5000; width: 468px; margin: 0px auto;">
<div style="position:absolute; margin-bottom:0px; z-index:15;">
<a href="Javascript:void(0);" onclick="document.getElementById('catfish').style.display='none'"><img src="http://secretdiarybd.com/wp-content/uploads/2015/05/close.gif.png" alt="close" height="20"></img></a>
