When you are writing CSS (Cascading Style Sheet) code, you are writing a set of rules that a page's HTML code must follow when rendering the page.
Every block of CSS rules has three important parts: The selector, properties, and values. The selector is what tells the page WHAT elements the following rules apply to, such as all divs with a name of "colorMeRed". Properties are what the page must change on the element, such as it's color. Finally, the value is what that property actually must be set to, such as "red".

Which selectors are used when you want to redefine the general look for an entire HTML tag?
You want to use a tag selector to define the look and feel of all tags of a certain type. These selectors are comprised of the tag itself, in front of the CSS declarations. p {font-weight:bold;} img {width: 245px;} Those will define the properties on all the paragraphs and images in the page.
How do CSS selectors work?
First, you have to define classes or IDs in your html content (for example, the area for your main content gets an id="content"). In your CSS, you can use #content (if it is an ID) or .content (if you specified class="content") to style it. Beware that IDs can be used only once in a HTML document whereas classes can be used multiple times.

What are the current revisions of CSS or what different levels of CSS exist not including unofficial candidate releases?
In terms of official revisions of CSS, you have CSS Level 1 (or CSS1 and became a Recommendation on December 17, 1996) which was the initial CSS version. The next major revision to CSS was the CSS Level 2 Revision 1 (CSS2.1 and became a Recommendation on June 7, 2011). When the World Wide Web Consortium (W3C) began working on the next version of CSS (what is colloquially called CSS3) they decided to break the process into multiple modules allowing different modules to be developed and implemented separately and incrementally. The only modules that have achieved Recommendation status (with the date the module became a Recommendation are in parenthesis) are: CSS Color Module Level 3 (June 7, 2011) CSS Namespaces Module Level 3 (September 29, 2011, edited March 20, 2014) Selectors Level 3 (September 29, 2011) CSS Print Profile (March 14, 2013) Media Queries (June 19, 2012) CSS Style Attributes (November 7, 2013) There are numerous other modules that are at different steps in the process of becoming Recommendations.
