The :active
CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the user presses down the primary mouse button.
/* Selects any <a> that is being activated */ a:active { color: red; }
The :active
pseudo-class is commonly used on <a>
and <button>
elements. Other common targets of this pseudo-class include elements that contain an activated element, and form elements that are being activated through their associated <label>
.
Styles defined by the :active
pseudo-class will be overridden by any subsequent link-related pseudo-class (:link
, :hover
, or :visited
) that has at least equal specificity. To style links appropriately, put the :active
rule after all other link-related rules, as defined by the LVHA-order: :link
— :visited
— :hover
— :active
.
:active
pseudo-class must only apply to the primary button; on right-handed mice, this is typically the leftmost button.Syntax
