Cascading Style sheets or commonly known as CSS help to define the appearance of a document that is written in web languages like HTML or XHTML (higher version of HTML). CSS is primarily used to add styles, color, and layout to an HTML document. Using CSS allows a user to alter the appearance of the HTML page that uses the CSS. It can also help order the document and structure content according to importance. Using CSS helps to eliminate the use of tables in an HTML document.
Web designers and programmers uniquely design any web page and point out the possible outline on PSD or a Photoshop document. Photoshop is the software in which you can edit and design graphics. And most webpages is written in HTML for the browser to read. In order to get a PSD file to an HTML file requires you to export the file in that format. There are plenty of options that you can select in Photoshop that will allow you to determine the size of the file, what the format is, and how it is sliced to be displayed in a browser.
HTML allows any image to be embedded and helps signify headings, links, lists and paragraph just to name a few. As well as defining the contents of the web page. And we need to convert PSD to HTML and CSS to make a web page recognizable by a particular web browser. Adding the CSS factor in the export of the PSD can help the web page dramatically in the search engine results and the validation of the webpage. It will likely improve the speed of the web page also.
There are more and more web 2.0 sites that utilize CSS at extreme levels. With the separation of design and content now created by blogs and content management systems it is more important than ever to learn how CSS can help your web page. And that will start from the moment you first export the original PSD file. Keep in mind before you ever export the file how you want to layout the images and the web page in general.
In addition to the speed gain and other advantages of CSS, one of the most important aspects of CSS is it’s ability to alter complete sites at once. When all your web pages are based on one CSS file, you can edit that file and change the appearance site wide. This is a huge advantage as you don’t need to edit every file on your web site.
