Here is an example of poor code. The text indent has two problems. It's in the HTML and it's 5%. It should be between 1em and 1.5em and it should be in the para class in the CSS.
Code:
<p class="para" style="text-indent:5%;">Vin watched the downy flakes drift through the air. Leisurely. Careless. Free. The puffs of soot fell like black snowflakes, descending upon the dark city of Luthadel. They drifted in corners, blowing in the breeze and curling in tiny whirlwinds over the cobblestones. They seemed so uncaring. What would that be like?</p>
Code:
.para {
display: block;
margin-top: 0%;
margin-bottom: 0%;
}
