Answer
- You don’t need two separate JavaScript functions. Only one called
toggleNav - Use Element.classList.toggle() to toggle a CSS class
- Don’t animate the
width. Usetransform: translateX(-100%)to hide the Nav, andtranslateX(0%)to show (open). - Don’t use links if you actually want buttons. Links (Anchors) are used to navigate
- Don’t use inline
on*JS attributes andstyleattributes
const toggleNav = () => {
document.querySelector("#mySidenav").classList.toggle("is-open");
};
document.querySelectorAll(".toggleNav").forEach(el => {
el.addEventListener("click", toggleNav)
});/* QuickReset */ * {margin:0; box-sizing: border-box;}
#mySidenav {
position: fixed;
overflow-x: hidden;
width: calc(100vw - 200px); /* try not to use fixed px */
height: 100vh;
z-index: 200;
top: 0;
left: 0;
padding: 60px;
background-color: #111;
color: #fff;
transition: 0.5s;
transform: translateX(-100%); /* hide it by minus own width */
}
#mySidenav.is-open {
transform: translateX(0%); /* show it */
}
.toggleNav {
padding: 1rem 1.3rem;
background: none;
