Hi @pixelsock, I would suggest to do the following:
Read the html responsive video tutorial for embes: http://forum.webflow.com/t/tutorial-responsive-video-using-html-embed/1316
Use the following code within the embed, of course replace the source url:<iframe style="position: absolute; top: 0; left: 0;"
webkitallowfullscreen mozallowfullscreen allowfullscreen>
In the above, where it says --vimeovideoid-- replace that with the vimeo video you want to display.
Next open the page settings and in the Before Body custom code, paste the following:
var iframe = document.querySelector('iframe');
var player = new Vimeo.Player(iframe);
Save changes and republish the site.
Here is an example site with a layout that i use a few interactions to change the size of the video when a user clicks a button:
I hope this helps, maybe give you some ideas!
