Using dots or colons in CSS effects

I'm working with css, so I don't know when to use dots and when to use colons for CSS efects, such as hover, active, visited. For example:

For list item named "tab", this code works:

.tab a.active
{ 
    text-decoration: none;
    background: #fff; 
}

When I use colon, effect doesn't apply:

.tab a:active 
{ 
    text-decoration: none;
    background: #fff; 
}

In the previous work, I use hover effect on ID element:

a:hover
{ 
    background-color:yellow;
}

This code worked. Is there a difference in these two effects, because in the first example, it is applied on class, and in the last example it is applied on ID?

dot is used to give styles to a class and colon is used for any effect to pseudoelement (that is an element in a id or class).

.class this is a class

#id this is an id

:after this is a pseudoelement

For example: #wrapper .button:hover means that you have your mouse over an element like this

<div id="wrapper">
   <div class="button">I'm a button</div> <!-- Mouse over this one -->
</div>

Let me know if it's useful.
