title: Using a frameset for a web app
body: <p>I am working on a web app consisting of 2 apps (one made by me, one 3rd party) residing side-by-side on one webpage. I have been using an <code>iframe</code> to embed the other app, but I want the size of the frame to be changed. Now, I could try going for a solution using javascript, but experience tells me, resizing in javascript is error-prone and inperformant. I am seriously considering to use a frameset in this case. </p>
  
  <p>The arguments against frames I have seen so far do not apply to my case in the slightest, nobody wants to bookmark only a part of the page, the 3rd party app can be accessed externally anyways.</p>
  
  <p>Now, I am wondering how bad the idea of using a <code>frameset</code> really is, I think I saw it being deprecated in the future, meaning support for it could be lost in near future? What other alternatives are there?</p>
