I am working on creating a responsive webpage that will show different navigation based on the viewport size. Currently, I have written this JavaScript code:
var shownav = document.getElementById('show-nav');
if (screen.width < "720"){
shownav.style.display = 'block';
}However, this code is not functioning as expected. Could someone please assist me with troubleshooting?
You don't need to rely on javascript for this task, as it can be accomplished using a media query:
#show-nav {
display: none;
background-color: red;
}
/* When the screen width is below 720px, #show-nav will become visible */
@media only screen and (max-width: 720px) {
#show-nav {
display: block;
}
}<nav id="show-nav">
Navbar
</nav>If you want to achieve this effect using only CSS, here's a possible solution:
body{
margin: 0;
}
nav{
width: 100vw;
background: yellow;
}
@media only screen and (min-width: 720px){
nav{
background: red;
}
}<nav>
<ul>
<li>Welcome</li>
</ul>
</nav@media only screen and (max-width: 720px) {
#show-nav {
display: block;
}
}
