title: Spaces around h1 tags
date: 2021-08-11
updated_at: 2021-08-15
layout: post
lang: en
ref: spaces-around-h1-tags

*EDIT*: Apparently, the behaviour below is consistent between Firefox and
Chromium for links, but not for `<h1>`.
My conclusion is that the `<h1>` behaviour is a Firefox quirk, but the `<a>` is
expected.
---
The HTML below has selectable extra spaces after `<h1>` tags:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>Spaces around h1 tags</title>
</head>
<body>
<main>
<h1>
With spaces around when selecting this heading
</h1>
<h1>Without spaces around</h1>
<p>
Is this expected behaviour?
</p>
</main>
</body>
</html>
```
The rendered output is:
<h1>
With spaces around when selecting this heading
</h1>
<h1>Without spaces around</h1>
<p>
Is this expected behaviour?
</p>
---
The same with links:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>Spaces after a tags</title>
</head>
<body>
<main>
<p>
<a href="#">
With extra underlined space
</a>
</p>
<p>
<a href="#">Without extra underlined space</a>
</p>
</main>
</body>
</html>
```
The rendered output is:
<p>
<a href="#">
With extra underlined space
</a>
after the link.
</p>
<p>
<a href="#">Without extra underlined space</a>
after the link.
</p>
