Hy all, I hope you are well.

I haven't made many questions so I will try to do it the best possible...

I have the following example table:

I have been trying to do and search for this for a lot of time but the people use other types of outputs or Jquery and I am just lerning Javascript.

Im trying to display a banner that says "correct" and color the button green after clicking the "correct button" and after 3 sec disappear the message and place the color of the button as before! I tried using SetInterval() or SetTime() functions but i cannot find anywhere how to display the message and color of the button for 3 seconds and not showing the changes again. That way another person can try answering the question without any hints (really frustrated after a couple of hours jaja).

Here is my code:

I am new to python and this website *I am having difficulties understanding why I'm getting the same value from my Car.name function

Please visit the page to see the problem in details https://ibnul.neocities.org/_temporary/au2pr11/au2pr11.html

Here I have 3 cards. Every one of them has a delete button. When clicked it triggers an overlay dialog to cancel or confirm. If I click the cancel it should go away which I have been able to do myself. But If I click the confirm button it should go away and also remove the card which delete button triggered the overlay dialog.

But the overlay dialog is a single one used for all the cards. And also all the cards has the same class name and I also want to keep it that way cause I want to copy paste this multiple time so I don't want to give different class or id name and write different function for each one. How do I detect the element on which the delete icon was clicked and then if user click the confirm button the whole card should disappear? And I want to remove the card by adding a class name called hide-res-card-outer on the res-card-outer element.

Please show it in pure JavaScript.

I'm creating a page to describe each class of my RPG game in sections (mage, bard, assassin, etc). In each section I have an image and a description of the character, and for each section I want to give different wallpapers with a white layer with 0.5 opacity over the wallpaper but I don't know how.

I tried adding different div tags for each section with different wallpapers but every new wallpaper covers all the page.

I'm going to show the code so far and you can see the results here and here
