Hola, uso Speed Page de Google para comprobar el rendimiento de mi web, y dice esto sobre mi css:
Código:
Very inefficient rules (good to fix on any page):
* #menu_superior ul li a:hover Tag key with 3 descendant selectors and hover pseudo selector
* ul.menu_principal li a Tag key with 2 descendant selectors and Class overly qualified with tag
* ul.menu_principal li a:hover Tag key with 2 descendant selectors and hover pseudo selector and Class overly qualified with tag
Inefficient rules (good to fix on interactive pages):
* #menu_superior ul li Tag key with 2 descendant selectors
* #menu_superior ul li a Tag key with 3 descendant selectors
* .info div:hover Tag key with descendant selector and hover pseudo selector
* table.mapa tr Tag key with descendant selector and Class overly qualified with tag
* table.mapa td Tag key with descendant selector and Class overly qualified with tag
* table.mapa img Tag key with descendant selector and Class overly qualified with tag
He mirado en internet y es completamente correcto hacerlo asi... y si no ¿Como se hace 'optimizadamente'?
Muchas gracias
