I read your code it's very clean.
I think you should use the @mediaqueries in your CSS.

This is resolve your problem ^^

hoping to help you

Thank you, really appreciate it even though I haven't even properly arranged all the html code and css.

Yeah I've  learned mediaqueries, but the problem is that you have to specify a specific  width, but I dont know which one because the images keep moving every little inch i adjust the resolution.

No, your code is easy to learn
But I don’t really understand why you want the billboard to get so small?

if you want to adapt your site you should probably pass the 2 sections welcome and language not to odds but more tot the welcome part at the top and the other at the bottom, and delete fluid.png or resize this.

I hope it helps you
