The kbd, samp, and code, elements all support fixed letter size and spacing.

The HTML code element defines a piece of programming code:


var x = 5;
var y = 6;
document.getElementById("demo").innerHTML x + y;

Notice that the code element does not preserve extra whitespace and line-breaks.
To fix this, you can put the code element inside a pre element:


var x = 5;
var y = 6;
document.getElementById("demo").innerHTML =x  + y;

The var element defines a variable.
The variable could be a variable in a mathematcal
expression or a variable in programmng context:
