Hello,
We’re having a problem with the Jetpack integration and having the gallery spanning the full width of the container.
I’ve tried editing the functions.php and installed the following plugin Custom Content Width – WordPress plugin | WordPress.org
Can somebody help?
Thanks 
This is true for all Jetpack widgets on the homepage. We’d really like a gallery to spread full width.

Hi @gemmaleighholyoak,
I hope you are well today and thank you for your question.
I visited your shared site but didn’t find any jetpack widget on home page.
Please advise.
Also please follow the indtructions provided on the below page in the section “Define a specific width for your galleries”
