Please the image. I want this feature in my website.
For eg: When I click the bowling tab, in the same page the text opens like a pop-up(not exactly like a pop-up). The text was hidden behind the other text.
Please see the website for further idea. Please help me urgently with the correct coding used in detail or with a helpful link.
