CSS & HTML Restyle for tool

Hi, I have had a tool built for me that generates a tag cloud for websites. https://www.honed.co/tag-cloud/

Would you please be able to help me to turn this landing page and tool into something more beautiful? I like tools to look like these:

https://httpstatus.io/
https://beautifier.io/
https://www.honed.co/density/
https://metatags.io/

In this, I need to also add:
- My logo (see the density tool above)
- A small explainer paragraph and headline (to help explain the tool)

The functionality of the tool needs to obviously be maintained. But you knew that right ;-)
