I've been asked by a client to add a "Show More" button after a pre-defined height on all pages on the users website.
It's naturally quite a difficult task to achieve because I have questions such as "what is a pre-defined height" (pixels/content??) but also we aren't just talking about plain text content here... It's going to be rich in HTML and there is going to be no way to create a positive experience for the actual end-users and eyeballs of his website.
Can you please help me explain why this would be a bad idea so that I can support my reasoning for suggesting they rethink this "Show More" with more substance...
