+## invalid_html_tags
+
+This lint **warns by default**. It detects unclosed or invalid HTML tags.
+For example:
+
+```rust
+/// <h1>
+/// </script>
+pub fn foo() {}
+```
+
+Which will give:
+
+```text
+warning: unopened HTML tag `script`
+ --> foo.rs:1:1
+  |
+1 | / /// <h1>
+2 | | /// </script>
+  | |_____________^
+  |
+  = note: `#[warn(invalid_html_tags)]` on by default
+
+warning: unclosed HTML tag `h1`
+ --> foo.rs:1:1

+2 | | /// </script>
+  | |_____________^
+
+warning: 2 warnings emitted
