Position a div in the center of the page horizontally

Can someone help me with aligning the #main div in the center of the page? I have this code snippet:

<div id="main" style=" margin:0 auto; ">
    <div style="float: left">
        <a style="display: block" href="#"><img src="test.gif"></a>
        <a style="display: block" href="#"><img src="test.gif"></a>
        <a style="display: block" href="#"><img src="test.gif"></a>
    </div>
    <div style="float: left">
        <a style="display: block;" href="#"><img src="ursus.gif"></a>
    </div>
    <div style="float: left">
        <a style="display: block" href="#"><img src="test.gif"></a>
        <a style="display: block" href="#"><img src="test.gif"></a>
        <a style="display: block" href="#"><img src="test.gif"></a>
    </div>
</div>

I want to ensure that the content is centered on the page. Any suggestions or solutions would be greatly appreciated. Thank you!

Answer №1

To ensure proper display, make sure to specify the width of the div:

<div id="content" style="margin:0 auto; width:800px;">

It is recommended to avoid inline css and instead utilize an external stylesheet like this:

#content {
   margin:0 auto;
   width:800px;
}
#content a {
   display:block;
}
#content > div {
   float:left;
}

<body>
<div id="container" style=" margin:0 auto; width: 960px;">
    <div style="float: left">
        <a style="display: block" href="#"><img src="cat.gif"></a>
        <a style="display: block" href="#"><img src="dog.gif"></a>
        <a style="display: block" href="#"><img src="bird.gif"></a>
    </div>
    <div style="float: left">
        <a style="display: block;" href="#"><img src="tiger.gif"></a>
    </div>
    <div style="float: left">
        <a style="display: block" href="#"><img src="lion.gif"></a>
        <a style="display: block" href="#"><img src="elephant.gif"></a>
        <a style="display: block" href="#"><img src="monkey.gif"></a>
    </div>
</div>
</body>

Answer №3

In response to a comment from Krister Andersson, you expressed the desire for the div element to be centered regardless of its width. However, in order to achieve this, some form of width information must be provided. If you prefer the div to have a flexible width but still appear centered, you will need to establish specific and equal margins:

#main {
    margin: 0 50px; /* or any other value in px, em, or % */
}

You can view an example at http://jsfiddle.net/jBYZq/.

The key is that either the element's width must be defined with margin: 0 auto, or equal margins need to be set on the element. Some form of specification is necessary to achieve the desired centering effect.
