I've added a form to my page and the form is showing up as centred on the page, but I need to have it aligned to the left.
Is there a way I can do this?
Your form isn't actually centered, the following style that I guess is in your theme's custom CSS options panel is adding a wide left margin.
I am not sure what reason it is there for but you have a few options
You've saved me a headache :)
