Steps for resetting a div's display after adjusting the device size

I have a code that displays horizontally on desktop screens and vertically on phones. It includes an x button (closebtn) that is only displayed on phones to close the menu bar. How can I automatically display it again after resizing the page back to desktop size?

function oty() {
  document.getElementById("tab").style.display = "none";
}
<div class="icon-bar" id="tab">
  <button class="closebtn" onclick="oty()">X</button>
  <button class="tablink">Home</button>
  <button class="tablink">News</button>
  <button class="tablink">Contact</button>
  <button class="tablink">About</button>
</div>

Answer №1

Best practice: Utilize CSS @media

Easily incorporate media queries to adjust the display of elements based on viewport size, a key aspect of implementing responsive design principles. In this scenario, sticking with CSS for styling is recommended, such as...

@media screen and (max-width: 1024px) { // Customize breakpoint size
  #tab {
    display: none;
  }
}

Avoid if possible: Using the resize event along with JavaScript

Although feasible through JavaScript, it is advisable to stick with CSS for these tasks. If necessary, here's how you can achieve it.

  1. Attach a resize event listener to the window: (e.g. 
    window.addEventListener('resize', handleResize)
    )
  2. Create a function to toggle visibility of your tab element.
  3. Consider implementing a throttle feature to prevent excessive event triggers.
