Hi, I’m putting a website together using the cavas theme and obviously have a blog page… however, one of the posts is very long – I just want to show an excerpt (a few lines) with a more button, but on the blog page it shows the whole post. How can I change it so that it shows an intro? Thanks. PS. Although I’m a novice I’ve already built a simple website and am now onto my second, this time with e-commerce – SCARY!
