Upsides and Downsides of Using CSS

On a web page there are various elements such as fonts, spacing, margin, etc. whose presentation need to be specified for formatting and presentation of information. At the same time, the presentation of these elements should be separate from the structure (headings, body text, links, etc.) of the web document to be published on that particular page. This is achieved by means of a technology referred to as Cascading Style Sheets, more popularly known as CSS. There are three types of Cascading Style Sheets namely, local (in-line), internal, and external.

• With the use of CSS, a web designer can separate content and presentation in web documents. This facilitates to modify a webpage's appearance without manipulating its HTML structure.
• There is greater control over formatting and display of HTML documents.
• Use of CSS is time saving as well. Conventionally, formatting was done by means of extensive, redundant HTML code but CSS allows formatting of web pages by scripting a few lines of code.
