I'm currently working on a page which features a block of text. This block of text can differ in length, depending on the users search term. On mobile I've decided to truncate the text and include a 'Read more' link. This text sits inside a expandable/collapsable block. When the user clicks on 'Read more' the block will expand to show the full text.
When the block is fully expanded, I want to include a link that will collapse the block back into the original position. I've currently chosen 'Close' as the link text, but I'm concerned it might be slightly ambiguous to users.
I've thought about using Show more/Show less, but as this is a block of text I think Read more is better suited.
