Resizer

The DHTMLX library provides a helper that changes the width and height of the page content based on the window size.

To create a responsive web page that will be easily adapted to different dimensions of a browser window, make use of the dhx.resizeHandler helper:

dhx.resizeHandler(container, function (width, height) {
    // some logic here
});

The helper takes two parameters:

container - an HTML element where the handler function is added to
handler - (function) a callback function that returns the container width and height after its sizes were changed
