Flash messages, or alerts, inform users of successful or pending actions. Use them sparingly. Don't show more than one at a time.

Default

Flash messages start off looking decently neutral—they're just light blue rounded rectangles.

<div class="flash">
  Flash message goes here.
</div>

You can put multiple paragraphs of text in a flash message—the last paragraph's bottom margin will be automatically override.

<div class="flash">
  <p>
    This is a longer flash message in it's own paragraph. It ends up looking something like this. If we keep adding more
    text, it'll eventually wrap to a new line.
  </p>
  <p>And this is another paragraph.</p>
</div>

Should the need arise, you can quickly space out your flash message from surrounding content with a .flash-messages wrapper. Note the extra top and bottom margin in the example below.

<div class="flash-messages">
  <div class="flash">
    Flash message goes here.
  </div>
</div>

Variations

Add .flash-warn, .flash-error, or .flash-success to the flash message to make it yellow, red, or green, respectively.

<div class="flash flash-warn">
  Flash message goes here.
</div>

<div class="flash flash-error">
  Flash message goes here.
</div>

<div class="flash flash-success">
  Flash message goes here.
</div>

With icon

Add an icon to the left of the flash message to give it some funky fresh attention.

<div class="flash">
  <!-- <%= octicon "alert" %> -->
  <svg width="16" height="16" viewBox="0 0 16 16" class="octicon octicon-alert mr-2" aria-hidden="true">
    <path
      fill-rule="evenodd"
      d="M8.893 1.5c-.183-.31-.52-.5-.887-.5s-.703.19-.886.5L.138 13.499a.98.98 0 0 0 0 1.001c.193.31.53.501.886.501h13.964c.367 0 .704-.19.877-.5a1.03 1.03 0 0 0 .01-1.002L8.893 1.5zm.133 11.497H6.987v-2.003h2.039v2.003zm0-3.004H6.987V5.987h2.039v4.006z"
    />
  </svg>

With dismiss

Add a JavaScript enabled (via Crema) dismiss (close) icon on the right of any flash message.

<div class="flash">
  <button class="flash-close js-flash-close" type="button">
    <!-- <%= octicon "x", :"aria-label" => "Close" %> -->
    <svg width="12" height="16" viewBox="0 0 12 16" class="octicon octicon-x" aria-label="Close" role="img">
      <path
        fill-rule="evenodd"

      />
