how are you? I hope everyone is fine, today I faced a problem and I can't find a way to make the title and controls have a dynamic height depending on their content when I'm using an iframe in the middle to make it have 100% of its height without making the screen scroll,I will attach an image so that you have an idea of the result I am trying to do and also attach my html code (I am new in stackoverflow please if there is anything you need, tell me thx:) )
