5,787 PointsAbout Quiz of Attribute Selector
The question is:
Consider the following HTML code:
<button type="button" class="close" data-close="modal">
Use an attribute selector to assign an element with a data attribute of data-close to the variable closeBtn:
var closeBtn = document.querySelector('???');
I filled in button[data-close="modal"] in the ??? place. I was wondering what the problem was. It did not pass the test. Thank you.

So select using the existence of the attribute only, without restricting it to specific contents.

5,787 PointsThank you Steven. May I seek your assistance to elaborate more?
The original question: var closeBtn = document.querySelector('???');
I tried to type in [data-close="modal"], but it showed incorrect. Then, I typed in data-close, but it also showed incorrect.

231,275 PointsYou still need the brackets around it to make it an attribute selector.
