Tableless web design
Tableless web design (or tableless web layout) is a web design philosophy eschewing the use of HTML tables for page layout control purposes.
Instead of HTML tables, style sheet languages such as Cascading Style Sheets (CSS) are used to arrange elements and text on a web page.
The CSS1 specification was published in December 1996 by the W3C with the aim of improving web accessibility and emphasising the separation of presentational details in style sheets from semantic content in HTML documents. CSS2 in May 1998 (later revised in CSS 2.1 and CSS 2.2) extended CSS1 with facilities for positioning and table layout. Around the same time, in the late 1990s, as the dot-com boom led to a rapid growth in the "new media" of web page creation and design, there began a trend of using HTML tables, and their rows, columns and cells, to control the layout of whole web pages. This was due to several reasons:
the limitations at the time of CSS support in browsers;
the new web designers' lack of familiarity with the CSS standards;
