wp_enqueue_style()

Enqueue a CSS style file.

Registers the style if src provided (does NOT overwrite) and enqueues.

Signature

wp_enqueue_style( $handle, $src = false, $deps = array(), $ver = false, $media = 'all' )

handle

 (string) Name of the stylesheet.

src

 (string|boolean) Path to the stylesheet from the root directory of WordPress. Example: '/css/mystyle.css'.
Default: false

deps

 (array) Array of handles (names) of any stylesheet that this stylesheet depends on. (Stylesheets that must be loaded before this stylesheet.) Pass an empty array if there are no dependencies.
Default: array()

ver

 (string|boolean) String specifying the stylesheet version number, if it has one. This parameter is used to ensure that the correct version is sent to the client regardless of caching, and so should be included if a version number is available and makes sense for the stylesheet.

Default: 'all'
