At the moment what you have there is defining the positions of your divs (boxes of your content) so for instance, let's take the first part of the code in the second link (ProjectSeven one)- you would simply add
a:link {
color: #333333;
}
after your code
#blog_left .item_class .item_class_panel{
margin-left:25px;
}
#blog_left #blog_comm{
margin-left:35px;
}
So essentially you'll have
#blog_left .item_class .item_class_panel{
margin-left:25px;
}
#blog_left #blog_comm{
margin-left:35px;
}
a:link {
color: #FF0000;
}
You'll hopefully have noticed that after each term is called (e.g. a:link) there's an opening and closing bracket - { and } - and in between these are the settings/values that you want. In this instance, you'll have set that you want the colour of your link to be #FF0000, which is red.
From the link above, here's a few that you can use
a:link
Describes any hyperlink that has not been visited by the user's browser. In other words, the page linked to is not present in the browser's local memory.
a:visited
Describes any hyperlink that has been visited and is present in the browser's local memory.
a:hover
Describes a hyperlink while the user's mouse happens to be hovering over it.
a:active
Describes a hyperlink that has been clicked but not yet released.
