Bulma icon element.
|
|
|
|
The icon element is a container for any type of icon font.
|
|
Because the icons can take a few seconds to load,
|
|
and because you want control over the space
|
|
the icons will take, you can use the icon class
|
|
as a reliable square container that will prevent
|
|
the page to "jump" on page load.
|
|
|
|
By default, the icon container will take up
|
|
exactly 1.5rem x 1.5rem.
|
|
|
|
The icon itself is sized accordingly to the icon library you're using.
|
|
For example, Font Awesome 5 icons will inherit the font size.

Renders an icon.
|
|
|
|
## For
|
|
|
|
The icon name is set using the `for` attribute.
|
|
|
|
## Color
|
|
|
|
Set color to `auto` to automatically choose/generate color
|
|
based on the icon name.
|
|
|
|
You can also set the color to any valid CSS color value.
|
|
|
|
## Size
|
|
|
|
The icon size can be set using the `size` attribute.
|
|
By default, the size is set to `1.5rem`.
|
|
|
|
Example:
|
|
|
|
<.icon for="home" />
|
|
|
|
<.icon for="info" color="auto" />
|
|
<.icon for="alert" color="#f44" />
|
|
<.icon for="settings" color="blue" />
|
|
<.icon for="error" color="hsl(0, 100%, 50%)" />
|
|
|
|
<.icon for="info" size="2rem" />
