web designing/ history:
- In 1996, Microsoft released its first competitive browser, which was complete with its own features and tags. The html markup for table was originally intended for displaying tabular data. HTML sites were limited in their design options, even more so with earlier versions of HTML. To create complex designs, many web designers had to use complicated table structures or even use blank spacer .Gif images to stop empty table cells from collapsing.CSS was introduced in December 1996 by the W3Cto support presentation and layout.

How the program treats the pixels is determined by whether the image is defined as a vector or a
bitmap. A bitmap file defines the position, color and size of each pixel. A vector program defines a line
of pixels and treats them as a single object. To change an object in a bitmap, you must change all the
pixels, so if a red box on a blue background needs to be smaller, you have to re-create a smaller red
box and change the pixels where the box was to the blue background. When you have a vector
image, you redefine the size and location of the lines. Each object is independent of the others and can be manipulated as needed.
