Displaying DOM elements on the web-page while looping over them

1

I am working on a landing page. I have 3 article elements, each of them has the property “display: none” and a class ‘art’. I want to display each of them while looping over them. They should appear successively: the previous ones must disappear at each iteration, that is why I have used var j in the code below But JS code displays them after the whole process of looping is completed. How to deal with it? Here: https://codepen.io/user_jacob/pen/oNjqWGg. Currently, I am doing it like this (which is not working):

function makeAppear() {
  var j = list.length-1;
  for (var i = 0; i < list.length; i++) {
    list[i].style.setProperty('display', 'block');
    list[j-1].style.setProperty('display', 'none');
  }
}

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at https://www.freecodecamp.org/learn.

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / repl.it / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
