15. Using CSS3
Where & when?

16. Not on the critical layers
don't use it on branding, layout & usability

17. Progressively enhance!
Make sure the website works in older browsers

18. Performance problems
Make your website fast!

19. Some examples!

20. p.rgba1 {
color: #000000;
color: rgba(0,0,0,1);
}
p.rgba2 {
color: #FF0000;
color: rgba(255,0,0,.5);
}
p.rgba3 {
color: #1ebdbe;
color: rgba(30,189,190,.25);
}
Always put the non-rgba color for older browsers before the rgba color

21. div.rgba1 {
background: #000000;
background: rgba(0,0,0,.8);
color: #FFF;
}
div.rgba2 {

32. <div class=”gradient1”></div>
div.gradient1 {
/* Basic color */
background-color: #183c7a;
/* Chrome, Safari4+ */
background-image: -webkit-gradient(linear, left top, left bottom,
color-stop(0%,#183c7a), color-stop(100%,#84b6f4));

background-image: linear-gradient(top, #183c7a 0%,#84b6f4 100%);
}
Always start with a solid color for older browsers

33. <div class=”gradient2”></div>
div.gradient2 {
/* Basic color */
background-color: #183c7a;
/* Chrome, Safari4+ */
background: -webkit-gradient(radial, center center, 0px, center center,
100%, color-stop(0%,rgba(24,60,122,1)),
color-stop(100%,rgba(132,182,244,0.5)));

background: -webkit-radial-gradient(center, ellipse cover,
rgba(24,60,122,1) 0%,rgba(132,182,244,0.5) 100%);
background: -moz-radial-gradient(Same as webkit)

background: radial-gradient(center, ellipse cover,
rgba(24,60,122,1) 0%,rgba(132,182,244,0.5) 100%);
}

34. <div class=”gradient3”></div>
div.gradient3 {

/* Chrome, Safari4+ */
background-image: -webkit-gradient(radial, center center, 0px, center
center, 100%, color-stop(0%,rgba(24,60,122,1)),

url(../images/pattern.png),
linear-gradient(top, rgba(0,0,0,.5) 0%,rgba(0,0,0,0) 100%);
background-color: #1EBDBE;

By setting background-color last you can simply only change the color

}
div.textoverflow2 {
white-space: nowrap;
overflow: hidden;
text-overflow: clip;
}
:hover {overflow:visible} makes the text visible again
