How to make link_to have custom class name in it?

Question

How would I generate the following link using Rails helper link_to?

<a class="bold" href="//address.com">A link</a>

When you go like this

.bold = link_to 'bla-bla-bla'

it produces

<div class="bold">
  <a href="blog/3">bla-bla-bla</a>
</div>

Answer 1

You need following:

= link_to 'A link', '//address.com', class: 'bold'

It will generate corresponding HTML:

<a class="bold" href="//address.com">A link</a>
