Single price grid component

Hi there 👋,

I submitted my second challenge. The experience was also relatively smooth. And I had a great chance to play with TailwindCSS and more of its Grid attributes.

I put utility classes into a dedicated CSS file, whilst using standard class names in the template. I tried to use BEM as a naming convention, but I am still not sure whether this is a good idea to use in Tailwind CSS.

Thank you, and have a great day. Radek
