CSS3 Advantages
Having got a detailed idea of CSS3 and its features with some of the vital attributes of CSS3 let us see the advantages or uses of CSS3 in brief in this section. There are numerous and variety of areas in which CSS3 makes it mark and thus users finds it one of the comfortable and powerful tools for usage thus making it a reason for its popularity. Let us see some of the important advantages and uses of CSS3 in detail.
Usage of style sheet:
Long before introduction of CSS3 in fact the Cascading style sheets concepts designers of web were using HTML markup to denote the font colors, background styles, border size. But after the introduction of Cascading style sheets concept all these got moved into a separate style sheet area thus making the users to have an easier and comfortable HTML markup. This gives another associated advantage of CSS3 are easier maintenance by which updations and changes are made only to the individual modules needed and testing of the individual modules is carried out and then integrating with the total system thus making the maintenance part very simple.
Differentiation and Isolation:
The concept of CSS3 helps users to have presentation separated from structure. That is for instance prior to the concept of CSS3 while users and web designers were using HTML markup the way of depicting or denoting a heading to be centered on the page in Bold, Blue with Ariel font would be as follows:
<h2 align="center">
<font color="blue" size="+6" face="Ariel">
<i>Usage of CSS</i>
</font>
</h2>
The above structure is very difficult to manage because the markup had to be repeated for each heading to apply wherever needed thus making more complex maintenance and presentation. But by the concept of Cascading style sheets and CSS3 the presentation separated from structure. That is clear differentiation and isolation is made where by the style sheet defines presentational characteristics and the structure of document defined in heading <h2>. Thus taking the following format:
<h2>Benefits of Cascading style sheets</h2>
h2 {
text-align: center;
color: blue;
font: bold "Ariel";
}
The above separation of presentation from structure concept helps the users to maintain in an efficient, easier and comfortable manner. Thus the modularized approach helps to develop and maintain the system on a per module basis and thus gives more flexibility to the system.
Helps to achieve Multi Column Layout:
Multi-Column Module is a vital feature present in CSS3.This feature enables users to flow the content of an element into multiple columns. The CSS3 Multi-Column Module is a important feature because it gives users the following features or advantages are there is no need to for users to scroll up and down while reading the text from one column to the next column, it prevents the need for horizontal scrolling, wraps text user friendly and easier to read without making too short words or lines and most of all everything could be embedded in a single page making it comfortable and economical. We have seen about this Multi-Column Module feature in detail in our earlier section of CSS3.
Flexibility in Handling:
The Cascading style sheets concept helps users to handle in a flexible and convenient way the web designing because it is possible to attach the CSS style information as a separate document or if the user wishes it is also possible to attach the CSS style information embedded within the HTML document. Also it is possible to handle multiple style sheets that is to say in other words multiple style sheets can be imported anywhere. It is also possible for users to specify many alternative style sheets which enable users to make a choice between them as needed. Thus the modularized approach of CSS3 helps to develop and maintain the system on a per module basis and thus gives more flexibility to the system .Thus greater control and flexibility is achieved at presentation level by user of CSS3 because of the advantages and powerful features of CSS3.
Handling multiple background images:
The drawback with CSS2 was that CSS2 allowed only a single background image per element. This drawback was removed in CSS3 by its capability of handling multiple background images per element.
Users find it amazing and powerful to use since it is possible to handle eight background images to a single element which is really a powerful feature of CSS3 ability. By this powerful feature of handling multiple background images per element users can create interesting effects of various kinds without the need of additional elements thus making it easier and efficient way of handling images and also the completion time is achieved faster. Also the selectors feature of Cascading Style Sheets Level 3 which we have seen in our earlier section in detail helps the developer to select specific levels of the document and work with it. Also added to this is this feature browsers support the feature of advanced Cascading Style Sheets Level 3 Selectors and thus making CSS3 more popular. In this context it is worth to mention about the border-radius command of CSS3 which is very useful for handling and bringing out rounded Corners without images with ease.
