I'm a CSS newbie looking to center a div on the screen at all times. I understand we can achieve this with positioning, but that typically requires fixed width and height. My goal is to have a fixed-width div without a set height. I want it to automatically adjust to the center based on its content using CSS.
If you are searching for the transform: translateY(-50%) property, check out this code snippet:
.container {
width: 200px;
position: fixed;
background-color: blue;
top: 50%;
left: 0px;
right: 0px;
transform: translateY(-50%);
margin: auto;
}
If you follow these steps, you can ensure that your content will always be centered.
HTML
<div id="outer">
<div id="content"></div>
</div>
CSS
* {
margin: 0 auto; /* centers everything except if otherwise floated
or affected by positioning positioning and margin property values */
}
#outer {
width: 200px;
height: auto;
}
#content {
width: 200px;
height: 100%;
position: absolute;
background-color: green;
bottom: 0;
}

Solution: I surrounded the specific DIV with a non-floated container that adheres to the first block of CSS code and ensured nothing would affect its positioning.
