Messed up css formatting on my site

Hello SI

Some how I messed up the formatting on my site.
For eg here;

Please see screen shot.

The docker gets messed up as well.
As of now I have turned of the docker as it looks like in the second screen shot.

Are you seeing the same messed up formatting at your end?

If so any idea what is going on/wrong?

thanks

Paul
