How can I make a bulma button goes full width?

Question

I am using [email protected] css framework

I have submit button within a form as follows

...
<!--Submit button-->
<div class="columns">
    <div class="column is-full">
        <button type="submit" class="button is-primary">
            <span class="icon"><i class="fa fa-sign-in"></i></span>
            <span>Login</span>
        </button>
    </div>
</div>
...

The result is the following

How can I make the button goes full-width ?

Solution 1

Add the class is-fullwidth

<button type="submit" class="button is-primary is-fullwidth">
      <span class="icon"><i class="fa fa-sign-in"></i></span>
      <span>Login</span>
</button>

Solution 2

is-fullwidth did not work for me, but is-overlay did!
