Deprecated HTML Elements

Checks for deprecated HTML tags like <center>, <font>, <marquee>.

What this check measures

We scan for deprecated elements: `<center>`, `<font>`, `<marquee>`, `<blink>`, `<frameset>`, `<applet>`. These are legacy HTML4 tags modern browsers still render but for how long?

Why it matters

Deprecated tags signal old, unmaintained code. They still render, but may be removed in future browsers. Also fail accessibility audits.

How our audit detects it

Scan HTML for deprecated tag names. Report count and locations.

Typical findings

  • error_outline<center> used instead of text-align: center CSS.
  • error_outline<font color="red"> — should be CSS.

How to fix

Replace with modern HTML5 + CSS. `<center>` → `text-align: center`. `<font>` → CSS styles. `<marquee>` → CSS animation (or just delete, nobody likes marquee).
