This document discusses various CSS3 properties for styling text and backgrounds, including text-shadow, gradients, multiple backgrounds, and border-image. It provides examples of how to use these properties with different values like offsets, colors, repeat patterns, and image files. It also notes browser-specific implementations using vendor prefixes for support across browsers.

3. text-shadow
#shadow1 { ● No inset value

vertical offset,

7. Gradienti
/*The Old Way*/
#linear­gradient {
background: #fff url(linear­
gradient.png) top repeat­x
}

9. #gradient1 {
/* Old browsers */
background: #1e5799;
/* W3C */
background: linear­gradient(to
bottom, #1e5799 0%,#7db9e8 100%);
}

10. Punto di partenza
● top
● top left
● top right
● bottom
● bottom left
● bottom right

background: linear­gradient(to right,
#3b679e 0%,
#2b88d9 50%,
#207cca 51%,
#7db9e8 100%);

12. Offeset
● si definisce pure il valore di offset (0%).

● E' il punto in cui il colore deve apparire

13. radial-gradient
background: radial­gradient(ellipse
at center, #3b679e 0%,#7db9e8
100%); /* W3C */
Forma del Gradiente:
● ellipse
● circle

14. Regole proprietarie
#gradient2 {
background: ­moz­linear­gradient(top, #1e5799 0%, #7db9e8
100%); /* FF3.6+ */
background: ­webkit­gradient(linear, left top, left bottom,
color­stop(0%,#1e5799), color­stop(100%,#7db9e8)); /*
Chrome,Safari4+ */
background: ­webkit­linear­gradient(top, #1e5799 0%,#7db9e8
100%); /* Chrome10+,Safari5.1+ */
background: ­o­linear­gradient(top, #1e5799 0%,#7db9e8
100%); /* Opera 11.10+ */
background: ­ms­linear­gradient(top, #1e5799 0%,#7db9e8
100%); /* IE10+ */
}
