```markdown
[Link button](http://example.com/){: .btn }
[Link button](http://example.com/){: .btn .btn-purple }
[Link button](http://example.com/){: .btn .btn-blue }
[Link button](http://example.com/){: .btn .btn-green }
[Link button](http://example.com/){: .btn .btn-outline }
```
### Button element
GitHub Flavored Markdown does not support the `button` element, so you'll have to use inline HTML for this:
```html
```

## Using utilities with buttons
### Button size
Wrap the button in a container that uses the [font-size utility classes]({{ site.baseurl }}{% link docs/utilities/typography.md %}) to scale buttons:
[Big ass button](http://example.com/){: .btn }
[Tiny ass button](http://example.com/){: .btn }
```markdown
[Link button](http://example.com/){: .btn }
[Tiny ass button](http://example.com/){: .btn }
```
### Spacing between buttons
Use the [margin utility classes]({{ site.baseurl }}{% link docs/utilities/utilities.md %}#spacing) to add spacing between two buttons in the same block.
[Button with space](http://example.com/){: .btn .btn-purple .mr-2 }
[Button ](http://example.com/){: .btn .btn-blue .mr-2 }
[Button with more space](http://example.com/){: .btn .btn-green .mr-4 }
[Button ](http://example.com/){: .btn .btn-blue }
```markdown
[Button with space](http://example.com/){: .btn .btn-purple .mr-2 }
[Button ](http://example.com/){: .btn .btn-blue }
[Button with more space](http://example.com/){: .btn .btn-green .mr-4 }
[Button ](http://example.com/){: .btn .btn-blue }
```
