Use of ID
ID is used on a single element all through the code. Example below shows for <p> and <div>.
In html:
<p id="c2">This is my paragraph.</p>
<div><h1>Welcome to my crummy site</h1> </div>
In css:
c2 {
color: red;
}
div {
color: red;
}
Use of class
You should use a class if you need to use the same selector more than once within a page or a site. While an ID is specific to a single element, classes can be assigned to multiple elements on a page or throughout the website.
In html:
<p class="bum">This is my paragraph.</p>
In css:
.bum {
color: red;
}
Use of type
In html:
<input type="button" value="Submit">
In css:
input[type="button"]{
background-color: navy;
color: white;
}
}
