Welcome to Treehouse!
There are definite reasons for using id. Take a look at this article over at css-tricks.com. It might shed some light on a few possibilities.
Happy coding,

Elements can have BOTH an id and a class. In fact, a single element can have MANY classes; simply include inside the quotes, separated with spaces.
<div id="good" class="luck sibal">Study Hard</div>
#good {
font-size: 10px;
}
.luck {
text-align: center;
}
.sibal {
color: steelgrey;
}
There are lots of really good CSS lessons in the library.

17,052 PointsHey Sibal!
Actually, there are DRAMATIC differences in their usage, and it mostly comes down to how specific you want to be. Obviously, classes are intended for "groupings" of code while ids specify a "unique" element. Sure, there are many powerful CSS selectors (http://www.w3schools.com/cssref/css_selectors.asp) that will allow you to pick through your code (written using only classes) to select one particular element in code for styling, but syntax is complex (i.e., prone to coding goofs).
The use of ids also becomes more important when you start using forms and server-side languages.
Keep up the good work! And keep an open mind on ids!
