How to use the !important tag in CSS

"CSS" stands for: "Cascading Style Sheets'. 

This means that the styles cascade and are applied in order as they are read by the browser. The browser reads CSS from top down. The first style is applied and then the second and so on. So if a style appears at the top of a style sheet and then is changed lower down in the document, the last one wins!

For example, in the following style sheet, the div class "text" will be white, even though the first style property applied is black:

#text{ color: #000000;}

#text{ color: #FFFFFF;}

The !important rule is a way to force styles out of order. A rule that has the !important property will always be applied no matter where that rule appears in the CSS document. So if you wanted to make sure that a property always applied, simply add the !important property to the tag.

So, to make the div class text always black, simply add the
"!important" tag right before the closing semicolon.

#text{ color: #000000 !important;}

#text{ color: #FFFFFF;}

To relate this back to SharePoint here are  few examples where you might need to use the !important tag to get your styles listen.

Example 1: You have applied a custom theme to a site. But on some of your pages the colors are inconsistent. Use the !important tag to force the class attributes so that all color behaviors act as expected.

Example 2: You are in the middle of creating your custom brand and notice that around the content area there is some hard coded margins. You could either create your own custom master page to fix this or you could force the margins the way you want them by using the !important tag.

I do not suggest using the !important tag for everything. Its a bit of a cop out. But there are some cases where it really does help keep your design functioning as your want it.

How To: Hide Left Side Navigation on Home Page

I was recently asked: "How can I hide the side nav bar on the main homepage layout ?? I want to be able to use the side NAV with in the team site etc etc, but I don't want it on the front page.. " There are a couple of ways to do this in SharePoint 2010. If you are using a non-publishing site you can add a Content Editor Web Part to the page and add the following to the HTML Source.
<Style>
body #s4-leftpanel
{
display: none;
}
.s4-ca
{
margin-left: 0px;
}
</style>
Basically the CSS above hides the left navigation Div, and then sets the content area to not have a left margin. Once you are done, simply modify the web part and hide it on the page. If you are using a publishing site for your homepage simply add the same styles specified above to a custom page layout. That way if you have a need for other pages that do not need the left side navigation you can re-use the page layout.

SharePoint 2010 Base CSS Classes

This will be the first of many SharePoint 2010 posts. I will be focusing on a few of the main CSS classes used for SharePoint 2010 Public Beta. As the product becomes more final there might be some changes to the class names but I will be sure to create a new post if that happens. This will be quite a lengthy but it should be helpful. The default CSS given below are just highlights of the full CSS attributes for that class.I will be using a basic team site as my base for the screenshots.
