 | |

 | |
| ## Description
 | |
| <section id="description"> Aquí hay otro ejemplo de animación continua con la propiedad de <code>animation-iteration-count</code> que usa el corazón que diseñó en un desafío anterior. La animación de un segundo de latido del corazón consta de dos piezas animadas. Los elementos del <code>heart</code> (que incluyen <code>:before</code> y <code>:after</code> piezas) se animan para cambiar el tamaño con la propiedad de <code>transform</code> , y la <code>div</code> fondo se anima para cambiar su color con la propiedad de <code>background</code> . </section>
 | |
| 
 | |
| ## Instructions
 | |
| <section id="instructions"> Mantenga el latido del corazón agregando la propiedad de <code>animation-iteration-count</code> tanto para la clase de <code>back</code> como para la clase del <code>heart</code> y establezca el valor en infinito. El <code>heart:before</code> y <code>heart:after</code> selectores <code>heart:after</code> no necesitan propiedades de animación. </section>
 | |
| 
 | |
| ## Tests
 | |
| <section id='tests'>
 | |
| 
 | |
| ```yml
 | |
| tests:
 | |
|   - text: La propiedad de <code>animation-iteration-count</code> para la clase de <code>heart</code> debe tener un valor infinito.
 | |
|     testString: 'assert($(".heart").css("animation-iteration-count") == "infinite", "The <code>animation-iteration-count</code> property for the <code>heart</code> class should have a value of infinite.");'
 | |
|   - text: La propiedad <code>animation-iteration-count</code> para la clase <code>back</code> debe tener un valor infinito.
 | |
|     testString: 'assert($(".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.");'
