What are the advantages and disadvantages of Cascading Style Sheets?
Advantages and Disadvantages Greater Control. Style sheets allow far greater control over the appearance of a document. Many different elements can be defined and customised, including margins, indents, font size, line and letter spacing. In addition, elements can be positioned absolutely on the page. Separation of Style and Content. By ensuring that the style and content of a document are kept separate, data is kept more coherent. In this way, as technologies such as XML and databases increase, there will be more scope for integration of existing HTML documents. Accessibility. Similarly, with the separation of style and content, documents are made more accessible to those with disabilities. When style sheets are used, software such as screen-readers are less likely to be confused by spurious code. For further information on accessibility issues, please refer to the W3C's page on the Accessibility Features of CSS. Smaller Documents. Because all tags or properties need only be defined once within a document, or even within a separate document, filesize can be reduced considerably. Easier Site Maintenance. As it is possible to link many pages to one individual style sheet, any sitewide changes can be made by simply changing the one file that the pages link to, instead of all the individual files. Browser Support. This is the one major drawback to style sheets. They are only supported at all by IE 3 and above and Netscape 4 and above, but even then, the way in which the two browsers interpret them can vary considerably. However, older browsers will still display your website, simply ignoring the elements they do not understand.Is there any function to find repeated value in an array?
