Can I Display HTML Content in CSS Content?

Is it possible to display an .html document , or .html fragment at CSS content?

The CSS content property allows you to specify the content of an element or pseudo-element. The content can be text, an image, or a URL. If the content is a URL, the browser will fetch the resource at that URL and display it inside the element or pseudo-element.

It is not possible to display an .html document or .html fragment directly in the CSS content property. However, there are a few workarounds that you can use to achieve a similar effect.

One workaround is to use an SVG image that contains the HTML document or fragment. The SVG image can then be referenced in the CSS content property. This method will work in all major browsers.

Another workaround is to use a data URI to embed the HTML document or fragment in the CSS content property. Data URIs are a way of encoding arbitrary data in a URL. To create a data URI, you prefix the data with the string "data:" followed by the MIME type of the data and a comma. For example, to create a data URI for an HTML document, you would use the following syntax:

data:text/html,<html><body><h1>Hello world!</h1></body></html>

Copy after login

You can then use the data URI in the CSS content property as follows:

content: url(data:text/html,<html><body><h1>Hello world!</h1></body></html>);

Copy after login

This method will work in most major browsers, but it is not supported in Internet Explorer.

Finally, you can also use a server-side script to generate the CSS content. The script can read the HTML document or fragment from a file or database and then output the content in a format that can be used in the CSS content property. This method is more complex than the other two methods, but it gives you more control over the content that is displayed.

Here are some examples of how to use the CSS content property to display HTML content:

/* Display an image of an HTML document */
content: url(image.svg);

/* Display an HTML document fragment */
content: url(data:text/html,<html><body><h1>Hello world!</h1></body></html>);

/* Display the contents of an HTML file */
content: url(file.html);

/* Generate the CSS content using a server-side script */
content: url(/script.php);

Copy after login
