Page Zoom

Hi all,
Am not sure if this is Java. I am after a web page zoom button.


Cheers

Most broswers provide this functionality through "text-size" or "page zoom"...

It can be done with javascript using a combination of elastic css layouts and relative text sizing.

Basically you have to set everything as a relative size, div widths, font sizes, border widths etc.. use em's as an example.

You set the body to have base size of 1em then can resize it with javascript using something like

Code: Select all

// increase

document.getElementsByTagName('body')[0].style.fontSize = (parseInt(document.getElementsByTagName('body')[0].style.fontSize) + 0.2) + 'em';

//decrease
document.getElementsByTagName('body')[0].style.fontSize = (parseInt(document.getElementsByTagName('body')[0].style.fontSize) - 0.2) + 'em';

Hope that helps
