The fist competitive browser was released by Microsoft in the year 1996 was comprehensive with its individual features and tags. The browser supported style sheets and was viewed at that time as a technique that is incomprehensible. In the beginning the HTML markup meant for tables was actually intended for tabular data display. But it was realized that complex and multi-columned layouts could be created by using HTML tables which remained otherwise an impossible feat.
More emphasis was paid on the aesthetics and designs at that time over good mark-up so web accessibility and semantics took backseats. With HTML created site design options were limited especially with the older versions of HTML. Designers had to use complex table structures or .GIF images in blank spacers to prevent the table cells that are empty from collapsing. In December 1996 CSS was introduced by W3C to support layout and presentation.
