In the mobile version of a website (width less than 620px), there is a button in the header. Clicking this button triggers the "mobileNav" function, which toggles the visibility of the mobile navigation between "display: none;" and "display: flex;". This functionality works well! However, a problem arises when the menu is opened at a screen width below 620px and then the screen size is increased; the mobile nav remains visible and cannot be closed due to design constraints.
A solution is needed to either revert the button back to its initial state ("Off") or override the styles that were applied by clicking the button when the screen size is increased. For instance, if clicking the button sets #mobile-nav to "display: flex;", resizing the screen should change it back to "display: none;".
Below is a code snippet with some messy CSS, but the key points are:
- "mobile-nav" is hidden on desktop screens
- "desktop-nav" is hidden on mobile screens
- The "mobileNav" function toggles "#mobile-nav" visibility when the button is clicked
- Currently, the "mobileNav" function does not close the mobile navigation when the screen is resized
Here is a simplified version of the JavaScript function responsible for this behavior:
// Mobile Navigation Function--------------------------------
function mobileNav() {
// Rotate Burger One and Reposition
var x = document.getElementById("burger-one");
if (x.style.transform === "rotate(45deg)") {
x.style.transform = "rotate(0deg)";
} else {
x.style.transform = "rotate(45deg)";
}
// Rotate Burger Two and Reposition
var y = document.getElementById("burger-two");
if (y.style.transform === "rotate(-45deg)") {
y.style.transform = "rotate(0deg)";
} else {
y.style.transform = "rotate(-45deg)";
}
// Toggle Mobile Nav Display
var z = document.getElementById("mobile-nav");
if (z.style.display === "flex") {
z.style.display = "none";
} else {
z.style.display = "flex";
}
}
// Rest of the script goes here...
