stop cascading style sheets from being overwritten

In my ASP.NET web forms project, I am utilizing Telerik controls.

The Problem

In one instance, I need to retrieve HTML data from the database, which includes a lot of CSS, images, and HTML content.

Here is an excerpt of my code:

<telerik:RadLabel ID="ProdDetails" runat="server" Text='<%# (HttpUtility.HtmlDecode((string)Eval("HtmlBody"))) %>'></telerik:RadLabel>

Although it functions properly, sometimes the HTML and CSS from the database take precedence over the site's CSS, causing instability on the site.

Therefore, I am seeking a solution to prevent incoming HTML from overriding my site's CSS styles.

Before downvoting or closing this question, please inform me if there are any missing details, mistakes, or necessary information.

Answer №1

Although the question may not have been phrased correctly, it's a common issue that many people face in practice.

After spending an entire day searching for a solution, I finally came across something that doesn't require updating the site's CSS or any other part.

The solution? An iframe.

Instead of rendering HTML within a div or another element, try using an iframe instead.

Check out the workaround I implemented:

<iframe frameborder="0" border="0" cellspacing="0" width="100%" 
  height="400px"  runat="server" id="test" 
  srcdoc='<%# (HttpUtility.HtmlDecode((string)Eval("HtmlBody"))) %>'>
</iframe>
