Changing font (wrap and size) in shopping cart

Site URL: https://www.mellah.co.uk

I am struggling to change the css to edit the font on the cart page. I have managed to change the font on all other pages.

You will need to add a product to cart and then go to the cart.

I want the text to not wrap on a mobile screen so the word  'shopping' is not broken over 2 lines. I would also like to know what css can directly affect the cart page.

This is what I have tried based on what worked elsewhere on the site

#cart
   div, h1, h2, h3 {font-size: 10px
   white-space: nowrap;
   overflow: scroll !important;
   }

but it is not affecting the page

Your like looks ugly with above code

Add to Design > Custom CSS

/* Shopping text mobile */
@media screen and (max-width:767px) {
h2.cart-title {
    font-size: 18px;
}
}
