Simple but effective (not really "dropping", though):
Code:
span.drop {
font-size: 200%;
font-weight: bold;
line-height: 0;
}
span.predrop {
font-weight: normal;
font-size: 50%;
}
span.letter_T {
margin-right: -0.15em;
}
<p><span class="drop letter_T"><span class="predrop">—¡</span>T</span>oma!...</p>
The class "predrop" is used for anything preceding the first letter. It's better to include it inside the "drop" span, in case you want to change it to something else... like a float. I also create "letter_?" classes for each letter that might need adjustments (T, V... in this case; A, L... for real drop caps). A simpler example:
