This is a test page for testing what letter is considered “first-letter” by your browser. For context, please see: What's a Letter in CSS's first-letter Pseudo-element?.
For each line in the following, their html is like this:
<div class="tt7654">x LATIN SMALL LETTER X (Letter, Lowercase)</div>
The css is like this:
div.tt7654:first-letter {font-size:xx-large; color:red}
Your browser is supposed to render the first letter large and red.
Here's what Firefox 3.5. shows:
In all major browsers (IE, Safari, Opera) of latest stable release as of 2009-07-28, all the first glyph are rendered large and red, regardless whether it is technically a letter.
