Create a Collapsed Sidepanel
Step 1) Add HTML:
Example
<div id="mySidepanel" class="sidepanel">
<a href="javascript:void(0)"
class="closebtn" onclick="closeNav()">×</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>
<button class="openbtn" onclick="openNav()">☰
Toggle Sidepanel</button>
<h2>Collapsed Sidepanel</h2>
<p>Content...</p>
Step 2) Add CSS:
Example
/* The sidepanel menu */
.sidepanel {
height:
250px; /*
Specify a height */
width: 0; /* 0 width - change this
with JavaScript */
position: fixed; /* Stay in place
*/
z-index: 1; /* Stay on top */
top: 0;
left: 0;
background-color: #111; /* Black*/
overflow-x: hidden; /* Disable horizontal scroll */
padding-top: 60px; /* Place content 60px from the top */
transition: 0.5s; /* 0.5 second transition effect to slide in the sidepanel */
}
/* The sidepanel links */
.sidepanel a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s;
}
/* When you mouse over the navigation links,
change their color */
.sidepanel a:hover {
color: #f1f1f1;
}
/* Position and style the close button (top
right corner) */
.sidepanel .closebtn {
position:
absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}
/* Style
the button that is used to open the sidepanel */
.openbtn {
font-size: 20px;
cursor: pointer;
background-color: #111;
color: white;
padding: 10px 15px;
border: none;
}
.openbtn:hover {
background-color: #444;
}
Step 3) Add JavaScript:
Example
/* Set the width of the sidebar to 250px
(show it) */
function
openNav() {
document.getElementById("mySidepanel").style.width
= "250px";
}
/* Set the width of the sidebar to 0 (hide it) */
function closeNav() {
document.getElementById("mySidepanel").style.width = "0";
