You’ve mixed a lot of randomly different questions into one thread, which will make it very difficult for the community to help you.
Split them out, show your work, what you’ve tried, and exactly where you’re stuck. Make an effort to find the answer yourself, otherwise you’re asking us to teach an HTML class, which is very difficult to do in a forum- and there are millions of those on the web already.
For Webflow-specific questions, you can also search this forum and the Webflow University as well to find everything you need.
