Hi there,
I have a 3 column layout as per below:

when I resize the window to around 675px wide (ipads and smaller screens), this occurs:

It then corrects at about 500px wide:

Not quite correct - the square button and text column are still too wide here.
Can you explain why this occurs at these sizes? How can I prevent this from occurring, and instead keep the picture taking up all of the width, with no interruptions from the title and square button?
