WebDevel Tips: Tutorial forme in CSS 3.0

CSS 3.0 vine cu foarte multe imbunatatiri care permit browserelor sa randeze o multime de forme fara a mai utiliza imagini.

In continuare aveti niste tutoriale despre forme de baza si speciale in CSS 3.0 folosind border-radius, box-shadow, gradient si multe altele (in acest articol nu am folosit imagini). Acestea sunt compatibile Firefox 3.5+, Safari, Chrome, Opera, IE 9+. Pentru IE 6-8 va trebui sa utilizati niste trickuri precum IE PIE (mai multe intr-un articol viitor).

 
 

Pentru demo-uri am utilizat gradienti CSS 3.0. La finalul articolului gasiti un link catre stylesheet-ul complet.

CSS circle – folosind border-radius

#circle {
	width: 100px;
	height: 100px;
	background: red;
	-moz-border-radius: 50px;
	-webkit-border-radius: 50px;
	border-radius: 50px;
}

Triunghi CSS

 
#triangle-up {
	width: 0;
	height: 0;
	border-left: 50px solid transparent;
	border-right: 50px solid transparent;
	border-bottom: 100px solid red;
}
 
#triangle-topright {
	width: 0;
	height: 0;
	border-top: 100px solid blue; 
	border-left: 100px solid transparent;

}

Stea in 5 colturi – CSS
