Add a closing button
importance: 5
There’s a list of messages.
Use JavaScript to add a closing button to the right-upper corner of each message.
The result should look like this:
To add the button we can use either position:absolute (and make the pane position:relative) or float:right. The float:right has the benefit that the button never overlaps the text, but position:absolute gives more freedom. So the choice is yours.
Then for each pane the code can be like:
pane.insertAdjacentHTML("afterbegin", '<button class="remove-button">[x]</button>');Then the <button> becomes pane.firstChild, so we can add a handler to it like this:
pane.firstChild.onclick = () => pane.remove();
