Developing a website on the webasyst platform

The site on the webasyst platform, there is a classic theme template, you need to make changes:
Set up the buy button in 1 click (it doesn’t work on iOS now)
Add 2 more sliders to the main (now there is one with new products, you need with discounted goods and popular)
Set up the blog titles to be clickable and move the button to the blog to the left.
Make the display of goods in 3 columns in the catalog, not in 4 as of now
