##Install

$3

To use Spinners straightaway without any package manager, the only file you'll need is stylesheets/_spinners.scss. Place this in the appropriate sass folder of your project, import it into your main .scss file or -module you deem fit, and you're good to go:

@import "spinners";

$3

To install in your current project using bower run:

$ bower install --save-dev spinners

$3

When installed via NPM, spinners can be used with eyeglass. To install spinners with NPM run:

$ npm install --save-dev spinners

$3

To install the Compass extension as a Ruby Gem:

$ gem install spinners

and require it in your config.rb:

require 'spinners'

If you're using Grunt or Gulp with grunt-contrib-sass or grunt-contrib-compass without a config.rb file and have the Ruby Gem installed, you can add Spinners as a dependency to your configuration object:

With grunt-contrib-sass:

sass: {
[...]
options: {
require: 'spinners'
}
}

With grunt-contrib-compass:

compass: {
compile: {
options: {
[...]
require: 'spinners'
}
}
}

With gulp:

[...]
.pipe(compass({
[...]
require: 'spinners'
}))
[...]

Spinners is also on Sache.

##Usage

First, import Spinner into your main .scss file or -module (depending on your installation method the import path might need to be adjusted accordingly):

@import "spinners";

Then declare a selector of your choice and call the mixin:

.my-loading-spinner {
@include spinner();
}

In your html, you can use any markup element you want, a div, span, i, or what have you.

Spinners come set to display: inline-block and vertical-align: middle by default so you can put it inside buttons, alerts and the like and have it aligned. If the defaults don't work for you, declare your overrides after calling the mixin:

.my-spinner {
@include spinner();
vertical-align: top;
margin-right: .5em;
}

$3

Size, border-width, -style, -color, and the speed of the animation can be customized.

#### Adjusting Size
By default, Spinners are set to be 1em wide and high, so a spinner will size proportionally to its context. To customize its size, you may use any valid dimensional unit such as px, em, or rem:

.my-spinner {
@include spinner(1.25em);
}

#### Adjusting border (width, style and thickness)
For adjusting the border, you may use any valid shorthand css border declaration or individual border-{property} {value} (no colon!) pairs:

.my-spinner {
@include spinner(3px solid #ccc);
}

.my-spinner {
@include spinner(border-width 3px, border-style solid);
}

#### Adjusting animation speed
To customize a spinner's animation speed, pass the number of seconds for one full rotation:

.my-spinner {
@include spinner(.6s);
}


#### Adjusting the Background
The background, i.e. the perceived non-rotating part of a spinner, is set to be transparent by default. To adjust the background, pass a color as background argument:

.my-spinner {
@include spinner(background rgba(0, 0, 0, .2));
}

All arguments are optional. When using mulitple customizations, pass your arguments comma-separated:

.my-spinner {
@include spinner(28px, 3px solid #555, .7s);
}

In case of invalid arguments compilation will not fail, but Spinners will output a warning and use its defaults.

Compatibility

Works in any modern browser and IE 10+.
Spinners does not come with a fallback for IE < 10, so if you need one, roll your own!
