How can I make product images full width on mobile using Impulse Theme?

I’m using Impulse Theme and is having problems with one section.

When product grid is shown in mobile, the images are so small. I want to show the images on their full width without losing the scrollable feature. As you can see, it shows 2 prodcuts. I want to show one product per scroll because the dimension is too small

In the bottom of your theme.css file add this code

@media only screen and (max-width:768px){
.grid-overflow-wrapper .grid__item.grid-product{
flex:0 0 80vw !important;
}
}
