The CSS Mess – Developing A CSS Strategy
One of the great benefits of CSS is that it substantially reduces the repetitious formatting code out of the HTML mark up and consolidate the same in the CSS which saves the programmers a great deal of time and effort. The styles can be reused to build multiple text blocks and control layout and formatting on multiple pages. The best part is that it considerably saves a lot of development time having all the reusable formatting in a centralized location, especially when you edit or update your website.
On the flip-side, CSS can get all messed-up as you keep on adding more styles to the style sheet. There are different styles to redefine HTML tag attributes, class and id selectors to format different text blocks, and also different styles for page layout. Again, while some of these styles are site wide, others are applicable to individual pages. Further, there are cross-browser compatibility issues and so forth. With all these stuffs going into the style sheet, often things become confusing unless you have developed a proper CSS strategy.
Devising Your CSS Strategy
Organize Your CSS Styles – The most common blunder quite a few web developers commit is that they put all the styles for the entire site into one CSS file. Although this approach works for a small site with a very few pages having specific styles, for the bigger sites it is better use multiple CSS files.
The key is to divide the style sheet file into different sections. For instance, in the main style sheet especially in the first section should contain the styles with the broadest site wide application, so it\’s mostly populated with styles that redefine the properties of HTML tags. The other section can contain styles to format common page elements, such as the navigation bar or footer. The styles that control site wide page layout can be placed in another section. Subsequent sections should create groupings of styles with a progressively more specific focus.
Many web developers tend to overuse classes and IDs. Though it is one of the basics of CSS to add classes and IDs to the markup and define CSS styles to format page elements, some developer however, get in the mindset of creating a class for every little thing that needs formatting. Instead, it is much wiser to redefine the properties of HTML tags than creating a different class.
Design for the best browser – Because of the its comprehensive use, most web coders tend to keep Internet Explorer browser in their mind while designing a web page. Later on, they make necessary adjustments in the style sheet to comply with other web browsers. Though, this looks pretty logical an approach. However, they by doing this they tend to write codes which contain all the idiosyncratic features of IE in the style sheet. As a result, it actually takes them a substantial time to make necessary adjustments in the codes for other browsers. Hence, they literally rework for a substantial portion of the code in the process.
If as a web developer, you want to produce standard-compliant code, then previewing Mozilla\’s Firefox instead of Internet Explorer would be much more helpful to you. First of all, Mozilla’s Firefox is the most standard-compliant browsers available at the moment. Secondly, it has the web developer tool bar extension on it which will help you a great deal. After you code for Mozilla’s Firefox, you can test it for the other browsers and add hacks and code tweaks to fix compatibility issues.
