What is the best way to ensure that all elements are perfectly centered in an

After conducting a thorough check, it has been confirmed that this post is not a duplicate. The circumstances surrounding my question are completely unique compared to other similar inquiries.

I am working with an ASP.NET page that has an unspecified width and height, and I am looking to center all elements within it, regardless of whether they are inline or block elements.

The <center> tag achieves the desired effect, but it is considered outdated.
Using text-align:center; does not always produce the desired results in various scenarios involving inline elements.
Similarly, using margin:auto; may not work as expected when dealing with block elements.

A piece of code that reliably centers elements across all web browsers is as follows:

<div style="float: left; position: relative; left: 50%;">
    <div style="float: left; position: relative; left: -50%;">
       my elements here
    </div>
</div>

While this code snippet works effectively in most cases, it can sometimes cause Rad Telerik Ajax popups to appear in unexpected positions outside the boundaries of the page.

With that said, what would be the precise equivalent of the <center> tag that ensures consistent cross-browser functionality?
I kindly request not to provide solutions that have already been mentioned in this post!

Answer №1

When it comes to achieving your goals, it's important to utilize all the methods at your disposal. For instance, email clients may not always support the latest technologies like external StyleSheets, so resorting to using the <center> tag can be a workaround for older render engines and browsers.

This highlights the idea of fallback and degradation in the presentation layer, rather than the behavior layer. The key focus should be on making sure essential functions like sending data back to the server via ajax work smoothly, even if it means compromising on design in certain browsers.

Also, have you considered applying centering styles to every element on your page with the following CSS:

*
{
text-align: center !important;
margin: auto !important;
}

Answer №2

In accordance with the wisdom shared by verbumSapienti: margin: 0 auto, however, a specified width is required for proper functioning.

item{ width: 50%; margin: 0 auto;}
