How can I run my project to know if its correct before posting it

I have finished my first project which is the tribute page on HTML and CSS but I dont know how to run it

Hi, welcome to the forum!

Put this script into the top of your HTML:

<script src=""></script>

Then click the green icon in the upper left corner. Select “Tribute Page” and click “Run Tests”. You should see which tests you pass or fail.
