CSS Question

Sidenav open on default instead of OnClick

I found this Sidenav on the internet which I would like to use for my application! Link to this: http://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_sidenav_none

<!DOCTYPE html>
<html>
<style>
body {
font-family: "Lato", sans-serif;
}

.sidenav {
display: none;
height: 100%;
width: 250px;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
padding-top: 60px;
}

.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s
}

.sidenav a:hover, .offcanvas a:focus{
color: #f1f1f1;
}

.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}

@media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}
</style>
<body>

<div id="mySidenav" class="sidenav">
<a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>

<h2>Sidenav Example</h2>
<p>Click on the element below to open the side navigation menu.</p>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>

<script>
function openNav() {
document.getElementById("mySidenav").style.display = "block";
}

function closeNav() {
document.getElementById("mySidenav").style.display = "none";
}
</script>

</body>
</html>


But, the sidenav only opens when the button is activated, but I would like it to be open by default. What syntaxes would I need to change for this?

Answer

All you need to do is remove the css that is hiding the sidenav by default

.sidenav {
    //display: none; - remove this line
    height: 100%;
    width: 250px;
    position: fixed;
    z-index: 1;
    top: 0;
    left: 0;
    background-color: #111;
    overflow-x: hidden;
    padding-top: 60px;
}
