widget in header

Hi
I used the instructions on this page

to insert a widget into the header – it worked however I have a couple of issues
it ended up looking like this

the issues are
1. the logo is now a lot smaller
its a lot larger when normal header is used – the uploaded image is a lot larger than the version that is displayed

2. there is a yellow background on the widget button
I cannot see where this is coming from and I have tried css background none & transparent but nothing seems to get rid of it

3. I’m using a fancy menu plugin
so I have tried many css things to hide the Enfold menu but have had no success

can somebody help me with some CSS or whatever to fix these issues

I have removed the customising code – but if you need it put back to answer this support request I will do so
