Sorry Rikard – the icon boxes now show up good, thanks for that

The testimonial box not really, very small underneath each other.
Also the two columns at the end still show up next to each other.

Any suggestions for those?

Thanks Rikard!

It did have an effect; the first of three boxes now shows up fine. The other two still show up next to each other, unreadable. Also the testimonial box (grey background) is not good yet.

Any other suggestions?

thanks Yigit!

I did add that, but still there is a bit of transparency. When scrolling, the grey header image shows through:

Any additional solutions I could try?
