Is there a web browser that supports HTML and CSS but without images, videos and audio?
Briefly

You might consider using a specialized browser or a modified version of an existing browser that filters out multimedia elements. Adjusting settings in a browser's preferences can help, although such options may be limited.
Creating a custom user stylesheet for a more traditional browser like Firefox or Chrome can help you block image, video, and audio tags while still allowing for CSS styling.
Some browsers like Lynx or Dillo support limited CSS and can be configured to disable multimedia content, but advanced styling options may be restricted.
While there may not be a mainstream browser fit for your exact needs, exploring accessibility-focused options or experimenting with user scripts could yield useful results.
