Explain why table-less layout is very important?
Answer:
There are several reasons why web designers should stop using tables for layouts, and adopt the use of CSS for controlling HTML layouts.
1) It adheres to current W3C web standards and it improves accessibility of the information to a wider variety of users, using a wide variety of user agents.
2) There are bandwidth savings as large numbers of semantically meaningless <table>, <tr> and <td> tags are removed from dozens of pages leaving fewer, but more meaningful headings, paragraphs and lists.
3) Layout instructions are transferred into site-wide CSS stylesheets, which can be downloaded once and cached for reuse while each visitor navigates the site.
4) If coded well, CSS makes it easy to apply global changes to the layout
5) Web pages often have less code, and are much thinner when XHTML and CSS are used
6) Sites may become more maintainable as the whole site can be restyled or re-branded in a single pass merely by altering the mark-up of the specific CSS, affecting every page which relies on that stylesheet.
7) New HTML content can be added in such a way that consistent layout rules are immediately applied to it by the existing CSS without any further effort.
