# Comments — HTML Fundamentals: Structure, Forms and Accessibility

Source: https://www.skillbyai.com/en/html/html-comments

> Add notes to your source with HTML comments, and remember that anyone can read them in page source.

## Comment syntax

Anything between `<!--` and `-->` is invisible on the rendered page.

```html
<!-- This is a comment, it won't be shown -->
<p>Visible text.</p>
```

## Not for secrets

Comments are invisible on-screen but still sit in the page source — anyone can view them, so never hide passwords or secrets there.
