Alignment of gallery

Hi, Love the Galleryview plugin, so thanks.

I have managed to line the edge of the gallery with the text on the right hand side but am a few pixels off on the left.

Could you please advise me on how, what and where i need to change code to make it align on the left also.

the site is https://stkewholidaycottages.co.uk

Many Thanks

Jon
