如何使用JQuery或CSS

Question

我试图使用我发现的here的JQuery函数来居中我的div。我尝试使用CSS将我的div居中，但它不起作用。任何我错的方向都会有所帮助。

抱歉页面格式化，但我试图将“allResults”div居中，其中包含我所有其他div（请参阅附带的代码）。根据我的理解，如果我可以居中主div（allResults，其中包含所有其他div），“allResults”div中的div也应该居中。

Answer 1

您可以只使用css居中，您设置width和margin 0为顶部和底部，auto使其居中。我还建议你不要使用id，如果你想改造使用类的样式。同样camelCase语法不建议用于css，最好使用some-class

<div id="allResult">
    ...
</div>

CSS

#allResult {
    margin: 0 auto;
    width: 1024px;
    overflow: hidden;
}
