Code to convert small case input in to Capital / Upper case

Using CSS –

style="text-transform:uppercase;"

Note-Using CSS text-transform: uppercase does not change the actual input but only changes its look. If you send the input data to a server it is still going to lowercase or however you entered it. To actually transform the input value you need to add javascript code as below:

Using Javascript - For your input HTML use onkeydown:

put this attribute in input feild onkeydown="upperCaseF(this)
In your JavaScript:
function upperCaseF(a){
setTimeout(function(){
a.value = a.value.toUpperCase();
}, 1);
}
