Cascading Style Sheets CSS

Style sheets separate presentation and content for web designs. The style is defined in an external style sheet file using style sheet language such as CSS.

Tips in testing your CSS layout

CSS layouts can be tested with the use of several software or applications. Opera can show the exact window dimensions in its title line, adjust window size on it to various sizes, and overlay the other browsers on that window for comparison. You can also test the URL in the IE Netrender’s web application.

How CSS style sheets work

A style sheet should be thought of as a set of instructions that suggests to a web browser how to draw a page. It is a series of instructions called statements which identifies the elements in an HTML document that it affects and it tells the browser how to draw these elements. Elements include paragraphs, links, and list items among others. Each statement has a declaration which tells a browser how an element should be drawn and it may contain any number of properties.

In creating style sheets, all key elements should be present. Each statement should have a declaration, telling how elements are to be drawn with their specific properties.

Cascading style sheets (CSS) is a style sheet language used to describe the look and formatting of a document written in markup language. It is most commonly applied to style web sites in HTML and XHTML. It enables separation of document content from presentation elements like layout, colors, and fonts.

Tips when creating a CSS layout

The most difficult thing in creating a CSS layout is getting it right. First, you must clear out the default padding and margin settings before you start. To center a layout, use a container div to contain all your content. Work from the top down by starting from the topmost elements in your design. Document what you are doing in case someday it needs debugging. Making comments inside your CSS file will help explain why you are doing things in a specific way. Choose a browser on which you are going to build your CSS and test from the start.

What to avoid when doing a CSS layout

A common mistake in making CSS layouts is browser incompatibility. This can be avoided by testing it from the start. You should also account for smaller browser resolutions. Your viewers may have a wide range of resolution. Avoid thinking that everyone else has the same sized monitor as you do. Mistakes such as not validating HTML, not considering frameworks, or not utilizing generic classes should be avoided. Also, using mammoth background images should be avoided.

Before creating a CSS layout, you should make sure to check for details like browser compatibility and to document your work. It would be time consuming to start all over again if every step is not well thought of.
