This is problem caused by safari attempting to default buttons in the mobile browser to its own apple look. A simple fix can be done using CSS. First add a class to your input button tag in the form which you may already have put there:

<input type="submit" value="SUBMIT" name="submit" class="mySubmitClass" />

then in your stylesheet add the following to fix the issue once and for all:

.mySubmitClass {
    -webkit-appearance: none;
}

To make text italic in CSS use the following:

font-style:italic;

This little CSS code snippet allows you to automatically attach an icon to file downloads. For instance if you had a file to download a pdf it would automatically add the icon to the right of the link.

<a href="news/issue12.pdf">View Latest Issue</a>

a[href $='.pdf'] {
padding-right: 18px;
background: transparent url(icon_pdf.gif) no-repeat center right;
}
