Screenshot of the W3C HTML Validator

When I first started building websites, I came across the W3C HTML validator which allowed me to validate whether the HTML I was writing was valid markup. I found the more I used the tool, the more it was helping me to become a better web developer as I was able to learn from any mistakes I made and learn to write better HTML markup.
