|
||
|
||
This repository is a module of the full [primer-css][primer-css] repository.
|
||
|
||
## Install

||
|
||
```
|
||
$ npm install --save primer-alerts
|
||
```
|
||
|
||
## Usage
|
||
|
||
The source files included are written in [Sass][sass] (`scss`) You can simply point your sass `include-path` at your `node_modules` directory and import it like this.
|
||
|
||
```scss
|
||
@import "primer-alerts/index.scss";
|
||
```
|
||
|
||
You can also import specific portions of the module by importing those partials from the `/lib/` folder. _Make sure you import any requirements along with the modules._
|
||
|
||
## Build
|
||
|
||
For a compiled **css** version of this module, a npm script is included that will output a css version to `build/build.css` The built css file is also included in the npm package.

|
||

|
||
|
||
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.
|
||
|
||
```html
|
||
<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.
|
||
|
||
```html
|
||
<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.*
|
||
|
||
```html
|
||
<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.
|
||
|
||
```html
|
||
<div class="flash flash-warn">
|
||
Flash message goes here.
|
||
</div>
|
||
```
|
||
|
||
```html
|
||
<div class="flash flash-error">
|
||
Flash message goes here.
|
||
</div>
|
||
```
|
||
|
||
```html
|
||
<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.
|
||
|
||
```html
|
||
<div class="flash">
|
||
<%= octicon "alert" %>
|
||
Flash message with an icon goes here.
|
||
</div>
|
||
```
|
||
|
||
## With dismiss
|
||
|
||
Add a JavaScript enabled (via Crema) dismiss (close) icon on the right of any flash message.
|
||
|
||
```html
|
||
<div class="flash">
|
||
<button class="flash-close js-flash-close" type="button"><%= octicon "x", :"aria-label" => "Close" %></button>
|
||
Dismissable flash message goes here.
|
||
</div>
|
||
```
|
||
|
||
## With action button
|
||
|
||
A flash message with an action button.
|
||
|
||
```html
|
||
<div class="flash">
|
||
<button type="submit" class="btn btn-sm primary flash-action">Complete action</button>
|
||
Flash message with action here.
|
||
</div>
|
||
```
|
||
|
||
## Full width flash
|
||
|
||
A flash message that is full width and removes border and border radius.
|
||
|
||
```html
|
||
<div class="flash flash-full">
|
||
<div class="container">
|
||
Full width flash message.
|
||
</div>
|
||
</div>
|
||
```
