Adding More Slant To Italic Text

You can simulate a custom slant with CSS3 skew transformations (although it will not look as great as a real italic font).

Here's an example:

HTML:

<p class="slant">Some text</p>

CSS

.slant {
    -moz-transform: scale(1) rotate(0deg) translate(0px, 0px) skew(30deg, 0deg);
    -webkit-transform: scale(1) rotate(0deg) translate(0px, 0px) skew(30deg, 0deg);
    -o-transform: scale(1) rotate(0deg) translate(0px, 0px) skew(30deg, 0deg);
    -ms-transform: scale(1) rotate(0deg) translate(0px, 0px) skew(30deg, 0deg);
    transform: scale(1) rotate(0deg) translate(0px, 0px) skew(30deg, 0deg);
}

You can also use

font-style: oblique 50deg;

(you can change 50 to what angle you want)
