I Need Help Pls

What website do i use to create my own web page using HTML and CSS?

Hey there @giannamac-thompson48 and welcome to the forums!!

There are a number of good host providers out there, both free and for a cost.
Though if you are just getting started and are only doing front-end work (HTML, CSS, JavaScript), I recommend git pages:

They host what is needed for a static front end website, entirely free and with no adds placed in your website.
