There are certain elements which are used in different ways. There are certain elements which have various properties. These properties.

These properties can be changed to bring out a different effect or output. These properties describe that element. So, the Properties that describe an element are called its attributes.

Some elements have one or more attributes, Following are the important points to remember about attributes: Attributes are always specified in the opening tag of the element. Most of the attributes are assigned some value by the help of ‘=’ sign.

Attributes can be assigned in any sequence in the opening tag.

It is not necessary to use all the attributes of an elements

Each attributes definition is separated from the other by a space.

A Primer on HTML Colour Codes

You have seen that attributes like bgcolor and text are given a colour name as value. There is a better way to specify colours. The three primary colours are Red, Green and Blue. All the other colours are the combination of various intensities of these three primary colours.

In HTML the colour are specified in hexadecimal notation. Hexa = 6 and decimal =10 i.e. base of hexadecimal notation is 16. The hexadecimal values range from 0 to 9 and then a to f i.e. 0 to f. 0 denotes least intensity of  a primary colour and f denoted the heighted the intensity.

The colour are preceded by # sign. For Example, for black colour, the intensity to all the three primary colours will be 0 so the notation for black in hexadecimal will be #000000. The first pair of numbers is for Red, middle pair for green and the last pair is for blue.

All Zeroes mean black. Can you guess, the colour  for white? Yes, Highted intensity value for RGB i.e.#ffffff. So, the combinations of the values from 0 to f of the primary colours can give you a huge range of different colours. Some rare colours are given here.
