How does CSS work? When a visitor loads one of your Web pages, by either typing in the address or clicking a link, the server (the computer that stores the Web page) sends the HTML file to the visitor’s computer along with any files linked to or embedded in the HTML file. Regardless of where the CSS code is, the visitor’s browser will interpret it and apply it to the HTML to render the Web page using that browser’s particular rendering engine that is then displayed in the browser window.

Setting the Table layout Different browsers use different methods to calculate how a particular table should be displayed. Two primary table-layout. Fixed method bases its layout on the width of the table and the width of columns in the first row. This method is generally faster than automatic.  Automatic uses the table column width along with the amount of content in the table data cell to calculate the table data cell width. This will generally render more slowly than the fixed method, but it also produces more accurate results for widths throughout the table.
