Font-size property dynamically proportioned to the browser window size

It's called viewport. It's the same to say browser window size.
We can assign to the font-size property a value expressed in percentage.
For example if the viewport width is 50 cm, assinging a font-size of 1vw matches to 0.5 cm.
So we give it simply:
a {
    font-size: 1vw;
}

Others use of dinamical font-size use should be:
- the vh: viewport height - for example: font-size:1vh;
- the vmin: the smaller between vw or vh - for example: font-size:1vmin;
- the vmax: the larger between vw or vh - for example: font-size:1vmax;

Bind or unbind html form to enter key pression

You should need to force the enter key pression, on a html form, to a javascript function(instead of the tag attribute action content).

$(document).ready(function(){
    $("#recoverUsernameFormId").bind("keypress", function(e) {
        if (e.keyCode == 13) {
            callYourFuncion();
            return false;
        }
    });
});


At the same way, you should need to unbind the enter key pression to the html form.


$(document).ready(function(){
    $("#recoverUsernameFormId").bind("keypress", function(e) {
        if (e.keyCode == 13) {
            return false;
        }
    });
});
