What I found out was the advantages of using CSS positioning and the benefits of creating tableless website layouts. The only time to use tables is when you are creating something from a spreadsheet or database. Besides when you create table you have to remember that table are inflexible, that nested tables load slowly, tables are not as accessible, and they don’t print well.
Image slicing is a process of taking an image and breaking it down into smaller part which will allow the web designer to make their images transfer at an optimal rate and helps to create larger graphics from the smaller graphics.
Slicing is useful to help optimize areas of an image without disturbing other areas and files. Also, tables are valid in XHTML when displaying tabular data, otherwise, if tables are used for layouts you are writing invalid XHTML codes.
