Thanks for your reply.
I went to ‘integral options’ then ‘custom code’ and then pasted the code you wrote into the ‘custom css’ section. The warning triangle (a triangle with a ! in it) comes up in the side bar to the left of the lines of code.
I tried changing all the values down to 0.1 to see what happened but it doesn’t seem to have made a difference. When I look at my website on my iPhone the ‘g’ from ‘fingerpicking’ is still on a different line to the rest of the word.
