Syntax vs. Semantics in programming languages like Python or Processing: If the Syntax is correct, the code is formally correct, it is valid. If the code does what it is supposed to do, it is intentional. Intentional programs are always valid. Valid programs are not always intentional.

Syntax and Semantics in HTML (Hypertext Markup Language): HTML is not a programming language JavaScript is a program HMTL does not encode instructions Web Browser are forgiving and will also render invalid pages whenever possible. Just because a page is looks intentional in a web browser it doesn't mean it's valid code. So maybe other or future web browsers will struggle to show the intended page. Use Validators like validator.w3c.org to make sure your code is valid.
