Making my ‘about’ page mobile friendly

Hello there,

I was wondering what you could do for me regarding making the images scale down in size viewing my site on a mobile (specifically the about section). On the mobile version presently the photo is cropped as it is a cover and full strech. I would like for it to resize on a mobile screen if possible?

My site is: studyfaster.co.uk (it will redirect you to study-fast.com as I’m in the process of changing my url), and I’m using the tesseract theme.

I have the custom css installed as beaver builder will not work with siteorigin active- and as I’ve made most my content with siteorigin it removes all my images.

Hope you can help,

Jordan Harry
