Can i change the screen dimensions in libGDX in HTML?

If I inspect the element (the game) in Chrome and I change canvas width or height it changes the screen dimensions, but I don't know how to do it in the HTML file. I have the default file generated by libGDX.

The CSS path to the canvas containing the screen size is: #embed-html > table > tbody > tr > td > canvas

The HTML is:

          <a class="superdev" href="javascript:%7B%20window.__gwt_bookmarklet_params%20%3D%20%7B'server_url'%3A'http%3A%2F%2Flocalhost%3A9876%2F'%7D%3B%20var%20s%20%3D%20document.createElement('script')%3B%20s.src%20%3D%20'http%3A%2F%2Flocalhost%3A9876%2Fdev_mode_on.js'%3B%20void(document.getElementsByTagName('head')%5B0%5D.appendChild(s))%3B%7D">&#8635;</a>
          <div align="center" id="embed-html"></div>
          <script type="text/javascript" src="html/html.nocache.js"></script>

          function handleMouseDown(evt) {
            evt.target.style.cursor = 'default';

          function handleMouseUp(evt) {
            evt.target.style.cursor = '';
          document.getElementById('embed-html').addEventListener('mousedown', handleMouseDown, false);
          document.getElementById('embed-html').addEventListener('mouseup', handleMouseUp, false);

(OP's own answer)

The solution to change the screen dimensions directly in the HTML/CSS is:

   div#embed-html table tbody tr td canvas{
     height: 480px;

That's where the screen is located.

I don't know if i understand your question correctly but in case you want to change the screen size of the game for webpage, you can do that by going to html game directory > src > yourpackage.client > HtmlLauncher.java and then modify resolution 480x320 to something else.

public GwtApplicationConfiguration getConfig () {
    return new GwtApplicationConfiguration(480, 320);

  • \$\begingroup\$ Yes, thats the way i know, to change the screen dimensions in the code before exporting, but i want to change them in the html. Example: style="width:100px". But the css path to the canvas where the screen is #embed-html > table > tbody > tr > td > canvas \$\endgroup\$ – Diogo Peres Sep 25 '15 at 16:31
