This function shows me more than 1000 products at the same time. That means I have a vertical scroll bar like this.

def All( request  ):
    p=product.objects.all()
    return render(request,'home.html',{'p':p})

I saw some websites load the images with scrolling, and the color of images before loading are solid and then the images appear.

This is an example from google

I want to know how can I achieve something like that?
