jQuery Awesome Cursor plugin
A jQuery plugin for using FontAwesome icons as custom CSS cursors. Also supports using a custom icon font instead of FontAwesome.
See https://jwarby.github.io/jquery-awesome-cursor/ for the full documentation and demos.
$('body').awesomeCursor('pencil');
Requires jQuery and FontAwesome.
Getting started
Installing the plugin
via npm
(recommended)
npm install jquery-awesome-cursor
<link rel="stylesheet" href="node_modules/font-awesome/css/font-awesome.min.css" type="text/css">
<script src="node_modules/jquery/dist/jquery.min.js" type="text/javascript"></script>
<script src="node_modules/jquery-awesome-cursor/dist/jquery.awesome-cursor.min.js" type="text/javascript"></script>
From v0.3.0
onwards, FontAwesome is marked as an optional dependency. If you plan on using jquery-awesome-cursor
with a different icon font, you can skip installation of any optional dependencies like this:
npm install --no-optional jquery-awesome-cursor
IMPORTANT: npm@3 won’t install peerDependencies
anymore, so if you haven’t already installed jQuery you will get an UNMET PEER DEPENDENCY
warning when you install. To fix, just do npm install jquery
.
via bower
bower install jquery-awesome-cursor
<link rel="stylesheet" href="bower_components/fontawesome/css/font-awesome.min.css" type="text/css">
<script src="bower_components/jquery/dist/jquery.min.js" type="text/javascript"></script>
<script src="bower_components/jquery-awesome-cursor/dist/jquery.awesome-cursor.min.js" type="text/javascript"></script>
IMPORTANT: from v0.3.0
onwards, you need to bring your own FontAwesome! FontAwesome is considered an optional dependency, but Bower doesn’t support optional dependencies - so you must install FontAwesome yourself. See #21.
bower install font-awesome
Manual installation
Download the production version or the development version. You will need to download and install FontAwesome manually as well.
In your web page:
<link rel="stylesheet" href="/path/to/font-awesome.min.css" type="text/css">
<script src="/path/to/jquery.js"></script>
<script src="path/to/jquery.awesome-cursor.min.js"></script>
RawGit CDN
You could also use RawGit’s CDN:
<link rel="stylesheet" href="/path/to/font-awesome.min.css" type="text/css">
<script src="/path/to/jquery.js"></script>
<script src="https://cdn.rawgit.com/jwarby/jquery-awesome-cursor/master/dist/jquery.awesome-cursor.min.js"></script>
Documentation
Setting a cursor
You can set a FontAwesome cursor on any element by calling awesomeCursor
, and passing the name of the icon you
want to use:
$('body').awesomeCursor('<icon name>');
See http://fontawesome.io/icons/ for a list of available icons.
Setting cursor options
Colour
Cursors can be any color you want, specified as a CSS color:
$('body').awesomeCursor('eyedropper', {
color: '#ff0000'
})
$('body').awesomeCursor('eyedropper', {
color: 'rgba(255, 255, 255, 0.75)'
})
$('body').awesomeCursor('eyedropper', {
color: 'cyan'
});
$('body').awesomeCursor('eyedropper', {
color: 'hsl(90, 100%, 50%)'
});
Size
Cursors can be any size (specified in pixels):
$('body').awesomeCursor('pencil', {
size: 32
});
Only pixel values are supported, as CSS cursor hotspots can only be specified in pixels.
Hotspot
The hotspot for a cursor can be defined, with an array containing the hotspot’s x and y offsets:
$('body').awesomeCursor('pencil', {
hotspot: [0, 17]
});
Or, using a string descriptor:
$('body').awesomeCursor('pencil', {
hotspot: 'bottom left'
});
String descriptors
The following values can be used in the hotspot string descriptor:
'center'
: positions the hotspot’s x and y offset in the center of the cursor'left'
: positions the hotspot’s x offset on the left of the cursor (equivalent to 0)'right'
: positions the hotspot’s x offset on the far right of the cursor (equivalent to cursorSize - 1)'top'
: positions the hotspot’s y offset at the top of the cursor (equivalent to 0)'bottom'
: positions the hotspot’s y offset at the bottom of the cursor (equivalent to cursorSize - 1)
The descriptors can be combined by space-separating them, e.g.:
'top left'
'center left'
'bottom right'
'top right'
- etc.
Flip
Cursors can be flipped horizontally, vertically, or in both directions, by setting the flip
option:
// Horizontal flip
$('body').awesomeCursor('pencil', {
flip: 'horizontal'
});
// Vertical flip
$('body').awesomeCursor('pencil', {
flip: 'vertical'
});
// Horizontal and Vertical flip
$('body').awesomeCursor('pencil', {
flip: 'both'
});
Rotate
A cursor can be rotated any number of degrees using the rotate
option:
// 45 degrees clockwise
$('body').awesomeCursor('pencil', {
rotate: 45
});
// 105 degrees anti-clockwise
$('body').awesomeCursor('pencil', {
rotate: -105
});
Outline
A cursor can be outlined in any color by setting the outline
option to any valid CSS color:
// Red outline
$('body').awesomeCursor('pencil', {
outline: 'red'
});
// White outline
$('body').awesomeCursor('pencil', {
outline: 'white'
});
Using a different icon font
As of v0.1.0
, a different icon font instead of FontAwesome can be used. To use a different font, the font
option must be set to
an object, specifying the font family and the CSS class format for icons. The example below shows how typicons
icons can be used instead of FontAwesome icons:
// Using 'typicons' icons instead of FontAwesome
$('body').awesomecursor('brush', {
font: {
family: 'typicons',
cssClass: 'typcn typcn-%s' // '%s' is the icon name ('brush')
}
});
In the above example, we set the font family
to ’typicons’, and set the cssClass
to the format that typicons
uses. %s
denotes the
icon name that is passed as the first argument to awesomeCursor
.
The cssClass
option can either be a string, as shown above, or a function:
// Using 'typicons' instead of fontawesome
$('body').awesomecursor('brush', {
font: {
family: 'typicons',
cssClass: function(name) {
// `name` is 'brush'
return 'typcn typcn-' + name;
}
}
});
You may want to set your replacement icon font as the default:
// Use 'typicons' as default
$.fn.awesomeCursor.defaults.font = {
family: 'typicons',
cssClass: 'typcn typcn-%s'
};
Note: the replacement icon font must use :before
pseudo elements with unicode content
Examples
/* Set the body element's cursor to a green pencil, with the hotspot located at the bottom left of the cursor (where the
* pencil tip is):
*/
$('body').awesomeCursor('pencil', {
color: 'green',
hotspot: 'bottom left'
});
// Set the cursor to be a big blue location arrow icon:
$('body').awesomeCursor('location-arrow', {
color: '#0050FF',
hotspot: 'top right',
size: 48
});
// Set the cursor to be a horizontally flipped version of the location arrow
$('body').awesomeCursor('location-arrow', {
color: '#0050FF',
hotspot: 'top right',
size: 48,
flip: 'horizontal'
});
// Set the cursor to be a red rotated left arrow
$('body').awesomeCursor('long-arrow-left', {
color: 'red',
hotspot: 'top left',
rotate: 45,
});
// Set the cursor to a black eraser icon with a red outline
$('body').awesomeCursor('eraser', {
color: 'black',
outline: 'red'
});
