I am having an issue as well. I have uploaded a picture of the mobile version of the site. It looks grainy not mobile friendly. I tried activating and deactivating mobile options on jetpack. Right now jetpack is completely deactivated. Is there code I can put in somewhere to fix the issue? I really like the theme so I would prefer not to switch themes if I can fix this.
Thank you
I am also having a problem with the billing form on my mobile website. The custumer has to clic on a square to suscribe to the new letter, to register an account or to agree. Only in the checkout form on mobile! Please help me! 
Hi @vitaebouffe
Please provide step by step explanation of how to replicate your problem and url to your website,
Okay so the url is https://vitaebouffe.com/commande/
You go in products and you select one item to add to the cart
then you go to the cart
you go for checkout and there is the form
you have to be on a phone to see what i mean.
the is some squares to select some options as suscribe to the newletter, register an account and agree to the terms
Do you need more informations?
Hello there,
Please try this:
.col-md-8.col-md-offset-2.col-sm-10.col-sm-offset-1.text-center {
background-color: black;
padding-top: 100px;
padding-bottom: 100px;
padding-left: 100px;
padding-right: 100px;
}
You can change those values as needed.
Best Regards,
Support

Im using woocommerce checkout form.
I can see that this template uses lines instead of checkbox. Its just that on a mobile it looks weird. Is there a way to change that?
