Description
animation-iteration-count
property that uses the heart you designed in a previous challenge.
The one-second long heartbeat animation consists of two animated pieces. The heart
elements (including the :before
and :after
pieces) are animated to change size using the transform
property, and the background div
is animated to change its color using the background
property.
Instructions
animation-iteration-count
property for both the back
class and the heart
class and setting the value to infinite. The heart:before
and heart:after
selectors do not need any animation properties.
Tests
tests:
- text: The <code>animation-iteration-count</code> property for the <code>heart</code> class should have a value of infinite.
testString: 'assert($(".heart").css("animation-iteration-count") == "infinite", "The <code>animation-iteration-count</code> property for the <code>heart</code> class should have a value of infinite.");'
- text: The <code>animation-iteration-count</code> property for the <code>back</code> class should have a value of infinite.
testString: 'assert($(".back").css("animation-iteration-count") == "infinite", "The <code>animation-iteration-count</code> property for the <code>back</code> class should have a value of infinite.");'
