When an HTML page or other type of web page loads like. With CSS, a web designer can set rules for the presentation of individual web pages or an entire site.
Traditionally, web pages were built using HTML with tables to layout the page structure and content. These cell based tables are very similar in form to a table found in Microsoft Excel and Word. An advantage of using tables is when used properly, it closely mimics the standard page layout in print media such as newspapers or magazine articles.
However, as web technology has advanced and become more dynamic, a new era of design with greater possibilities has emerged. A new approach to designing and laying out web pages was created to break the constraints of structured table layouts. This approach is called CSS tableless design.
A DIV is a box, or more accurately described as a container, where web content is housed. Similar to table based design where content is contained within the cells of the table, with DIVs the content is housed inside DIV containers.
CSS tells the DIV where to appear on a web page, its width and height dimensions, and its appearance i. Instead of being constrained by the rigid grid structure of tables, DIVs can be made any size and placed anywhere on a webpage including layered on top of each other.
To make the changes, you only need to make several alterations in the mark up of the CSS and immediately the changes are effected. For those who were asking, what is tableless HTML? By Scriptcase ,.
October 4, After the big Scriptcase 9. Follow the latest news for the month of October! Next up lets write the CSS code to center everything. Lets draw a border for all the containers and set marging and padding values to align then neatly.
As you see in the picture the margins of the sidebars if generalized will not align straight with the header and footer. Finally we set the width and float the elements to achieve the three column layout. Often, each row is a single entity like an employee , and each column represents a particular attribute like 'first name', 'date of birth', etc.
Another rule for me is, could the data in the table be sortable and pagable? If not, you're probably mis-using tables for layout.

Tables should be used for displaying tabular data, not for layout. David Poeschl David Poeschl 4 4 silver badges 11 11 bronze badges. Tableless web design gives you the following: Less Markup Tables need a lot of code to actually create table cells and rows, where as a div is only a simple open and close tag. Easier Maintenance Since there's less markup with tableless design, the code is easier to maintain less code to wade through.
Content and Presentation are Separate This one is key. Tables are for Data Tables should be used when you're displaying tabular data.
