Thanks for taking a look.
That shade of orange is their thing and they wanted that colour to be prominent, their vehicles and clothing are the same and it is how they are known really. I agree that it is a bit harsh on the eyes.
As far as the container div goes, it was working perfectly until someone starting messing with the theme editor after the site had gone live. The company control the content and have their own hosting, I just made the theme. I have noticed that sometimes the problem is not there depending on what is on the page at the time.
Do you think the overall design looks ok, not too amateurish?
I have been asked by a few other people to create websites for them but as I don't do this for a living I am a bit over critical of what I create and end up spending a lot of time tinkering with small things. I suppose once someone offers to pay you to do a job it changes the way you look at it.
