Flash messages, or alerts, inform users of successful or pending actions. Use them sparingly. Don't show more than one at a time.
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 overridden.
<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 moretext, 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>
Add .flash-warn, .flash-error, or .flash-success to the flash message to make it yellow, red, or green, respectively.
<div class="flash">Flash message goes here.</div><div class="flash mt-3 flash-warn">Flash message goes here.</div><div class="flash mt-3 flash-error">Flash message goes here.</div><div class="flash mt-3 flash-success">Flash message goes here.</div>
Add an icon to the left of the flash message to give it some funky fresh attention.
