Vanilla Js Display None

The Basics of Displaying and Hiding Elements in Vanilla JS with ‘display: none’

Displaying and hiding elements in vanilla JavaScript can be accomplished through the use of the CSS property ‘display’ with the value of ‘none’. This property can be used to completely hide an element from view, and then easily make it visible again when needed.

To hide an element using ‘display: none’, simply select the element using JavaScript and then set the ‘display’ property to ‘none’, like so:

  const element = document.querySelector('#my-element'); = 'none';

This will set the display property of the element with the ID of ‘my-element’ to ‘none’, making it completely hidden from view on the web page.

To make the element visible again, simply set the display property to its default value, such as ‘block’ or ‘inline-block’, like so: = 'block';

This will set the display property back to its original value, making the element visible again on the web page.

Using ‘display: none’ in this way can be a powerful tool for web developers who need to dynamically show or hide elements based on user interactions or other events that occur on a web page.

Understanding the CSS ‘display’ Property for Dynamic Element Control in Vanilla JS

CSS ‘display’ property is one of the most important properties that allow developers to control the visibility and layout of HTML elements. In Vanilla JS, understanding how to manipulate the ‘display’ property is crucial for building dynamic and interactive web applications.

The ‘display’ property controls how an HTML element is displayed on the page. By default, every HTML element is displayed in a certain way according to its tag (e.g., a

element is displayed as a block element, while a element is displayed as an inline element). However, with the ‘display’ property, developers can change an element’s default display behaviour to suit their needs.

One of the most common uses of the ‘display’ property in Vanilla JS is to dynamically show or hide elements based on user actions. For example, let’s say you have a button that toggles the visibility of a section on your web page. To achieve this effect, you can use Javascript to manipulate the ‘display’ property of the section element.

Here’s an example of how you can use Javascript to toggle the visibility of an HTML element:

// Get the HTML element
const element = document.getElementById(“myElement”);

// Toggle the visibility on click
document.getElementById(“myButton”).addEventListener(“click”, function() {
if ( === “none”) { = “block”;
} else { = “none”;

In the above code, we first get the HTML element we want to manipulate using Vanilla JS. We then add an event listener to a button (with the id “myButton”) that toggles the visibility of the element when clicked. If the element’s ‘display’ property is set to ‘none’, we change it to ‘block’ to show the element. Otherwise, if the ‘display’ property is set to ‘block’, we change it to ‘none’ to hide the element.

In addition to showing or hiding elements, the ‘display’ property can also be used to control the layout of elements on the page. For example, setting an element’s ‘display’ property to ‘flex’ allows developers to create responsive and flexible layouts that adjust to the screen size.

Overall, understanding how to use the ‘display’ property in Vanilla JS is an essential skill for any web developer. With this powerful property, developers can control the visibility and layout of elements on the page, creating dynamic and responsive web applications that provide a better user experience.

Advanced Techniques for Hiding and Revealing Multiple Elements in Vanilla JS

When it comes to hiding and revealing multiple elements in Vanilla JS, we have a few advanced techniques that can come in handy. These techniques can be especially useful in scenarios where we need to toggle the visibility of multiple elements based on user interaction or other events.

One technique is to assign a class to all the elements that need to be hidden or revealed. We can then use CSS to define the styles for this class, including the “display:none” property to hide the elements by default. To reveal the elements, we can use JS to remove the class from the elements, causing them to inherit their visible styles.

Another technique is to use the “data-” attribute to define custom attributes that can be used to store data associated with the elements. We can assign a “data-” attribute to each element that needs to be hidden or revealed, and use JS to manipulate these attributes to toggle the visibility of the elements.

Finally, we can use the DOM traversal methods to target specific elements that need to be hidden or revealed based on their relationship to other elements in the DOM tree. This can be especially useful in scenarios where we need to target elements that are nested inside other elements.

Overall, these advanced techniques can help make your Vanilla JS code more flexible and efficient when it comes to hiding and revealing multiple elements.

Using JavaScript Event Listeners to Trigger ‘display: none’ and Other CSS Properties

One powerful aspect of JavaScript is the ability to manipulate the DOM and CSS styles.

With JavaScript event listeners, we can target elements on our webpage and listen for certain events that occur. Then, we can trigger CSS properties such as “display: none” to hide an element or “opacity: 0” to make it invisible.

For example, let’s say we have a button with an ID of “myBtn”. We can add an event listener to listen for a click event on that button:

const myBtn = document.getElementById('myBtn');

myBtn.addEventListener('click', function() {
// code to trigger CSS property

Inside the event listener function, we can add code to trigger the desired CSS property:

const myBtn = document.getElementById('myBtn');
const myDiv = document.getElementById('myDiv');

myBtn.addEventListener('click', function() { = 'none';

In this example, when the button with the ID “myBtn” is clicked, we target the div with the ID “myDiv” and set its “display” property to “none”. This will hide the element from the webpage.

JavaScript event listeners give us a lot of flexibility in terms of manipulating CSS styles on our webpage. By utilizing them, we can create dynamic and interactive experiences for our users.

Cross-Browser Compatibility Tips for Displaying Elements in Vanilla JS

When working with JavaScript, cross-browser compatibility is always a concern, especially when it comes to displaying elements. Here are a few tips to keep in mind to ensure your elements are displayed consistently across different browsers:

  • Use textContent instead of innerText to set the text content of an element. This will ensure that your text is displayed consistently across different browsers.
  • Use classList.add() to add a class to an element instead of setting the className property. This is because some browsers may not support the className property.
  • When using CSS to display or hide an element, use classList.add() and classList.remove() to add and remove classes instead of manipulating the style property directly. This will ensure that your CSS changes are applied consistently across different browsers.
  • Use the getAttribute() method to get the value of an attribute instead of accessing it directly on the element. This will ensure that the attribute value is returned consistently across different browsers.

By following these tips, you can ensure that your elements are displayed consistently across different browsers when working with Vanilla JS.

Creating Elegant Animation Effects with ‘display: none’ and Vanilla JS

Animation effects can help to improve the user experience on your website by adding visual interest and emphasizing important elements. While there are many libraries and plugins available to create animations, sometimes all you need is a little bit of Vanilla JS to get the job done.

One way to create elegant animation effects is by using the CSS property display: none alongside Vanilla JS to hide and reveal elements. By toggling the display property with JS and using CSS transitions, you can create smooth and sophisticated animations without the need for additional libraries.

To get started, you can use the classList property in Vanilla JS to add and remove a class that sets the display: none property on an HTML element. Then, use CSS transitions to animate the transition between the hidden and visible states:

// JS
const element = document.querySelector('.my-element');

// CSS
.my-element {
    opacity: 0;
    transition: opacity 0.5s ease-in-out;
.my-element.visible {
    opacity: 1;

In this example, the JS code removes the hidden class from the HTML element and adds the visible class, which sets the display property to block or inline depending on the element’s original display value. The CSS code sets the initial opacity of the element to 0 and adds a transition on the opacity property to create a fade-in effect when the element becomes visible.

Overall, using Vanilla JS and the display: none property is a simple but powerful way to create elegant animation effects on your website. With a little bit of code and creativity, you can make your website more engaging and dynamic without relying on external libraries or plugins.

Debugging Common Issues with ‘display: none’ in Vanilla JS

While using ‘display: none’ in Vanilla JS, developers may come across a few common issues that can cause unexpected behavior. Here are some tips to debug these issues:

  • Check for typos: Make sure that the property is spelled correctly and that all necessary characters are included, such as semicolons and colons.
  • Check for scope: Make sure that the element you are trying to hide or show is within the scope of your code. If it is outside the scope, your code will not work.
  • Check for conflicting CSS: Other CSS rules may override your ‘display: none’ property. Check that no other CSS rules are hiding or showing the element.
  • Check for events: If you’re using ‘display: none’ to hide an element to be shown later via a user click or hover event, make sure that event is properly set up and firing as intended.
  • Use console.log: If all else fails, use console.log to debug your code. You can log the element you’re trying to hide or show and check its properties to see if something is amiss.

Debugging common issues with ‘display: none’ in Vanilla JS can seem frustrating, but with these tips, you can easily identify and fix the issues you may encounter.
