## Some general rules

In HTML5 pressing enter button does not make new row. In order to get new row in HTML5 we need to use element br
In HTML5 several sequential whitespaces will be replaced with ONE whitespace. You need to use special character to get more tha 1 whitespace.
Sample:
one two three
In order to keep your own design, the element pre can used

       one
                         two

    					               three

## Special Characters

Special character will start with and sign and end with semicolon, between start and end symbol is code of the special character
Sample:
code for less than sign < is: lt
code for more than sign > is: gt
code for whitespace is: nbsp
let make 10 whitespaces using special chartacter

## Using SPAN and DIV Elements

Elements SPAN and DIV are used for markup only, since adding these elements to web page does not have any changes
Element SPAN is used in cases where is needed to markup less than one row
Sample:
At 10.00 on Sunday is most important lecture!
Element DIV is used in case where we need to markup more than 1 row
