Applying CSS

There are three types of applying CSS to html. They are as follows...
1) Inline
2) Internal
3) External

In-line:

In-line styles are put straight into the HTML tags using the style attribute.
Ex: <p style="color: red">Blog</p>

Internal:

Embedded, or internal styles are used inside the head tags.
Ex: <style type="text/css">
a {
color: blue;
}
</style>

External:

External styles are used for the multiple-page website. Used inside the head tags
Ex:<link rel="stylesheet" type="text/css" href="style.css" />
