This code is for a website that prompts the user to guess which historical Mexican event took place first. It works how I want other then that I want the year each event took place to be displayed underneath each option after the user makes their selection.

I tried experimenting with event listeners to trigger when a button is pressed and have the year displayed but I couldn’t get anything to work. I think this is currently beyond my abilities but I am open to learning new things. Thank you to anyone who helps.

You have not written the code for displaying year. Here is your modified code which displays year.

Hope this helps.

I assume you want the year to show up below the text on the button when it is clicked? However, with you calling the selectItems function in the event listener, the text will be overwritten when it is clicked, so a delay has to be added. More information in the comments.
Also your game-board div has no closing tag.
