Skep 'n gordynspyskaart
Stap 1) Voeg HTML by:
Voorbeeld
<!-- The overlay -->
<div id="myNav" class="overlay">
<!-- Button to close the overlay navigation -->
<a href="#"
class="closebtn" onclick="closeNav()">×</a>
<!-- Overlay content -->
<div
class="overlay-content">
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>
</div>
<!-- Use any element to open/show the overlay navigation menu -->
<span onclick="openNav()">open</span>
Stap 2) Voeg CSS by:
Voorbeeld
/* The Overlay (background) */
.overlay {
/* Height
& width depends on how you want to reveal the overlay (see JS below) */
height: 100%;
width: 0;
position: fixed; /* Stay in place */
z-index: 1; /*
Sit on top */
left: 0;
top: 0;
background-color: rgb(0,0,0); /* Black fallback color */
background-color: rgba(0,0,0, 0.9); /* Black w/opacity */
overflow-x: hidden; /* Disable horizontal scroll */
transition: 0.5s; /* 0.5 second transition effect to slide in or slide down
the overlay (height or width, depending on reveal) */
}
/* Position the content inside the overlay */
.overlay-content {
position: relative;
top: 25%; /* 25% from the top */
width: 100%; /* 100% width */
text-align: center; /*
Centered text/links */
margin-top: 30px; /* 30px top
margin to avoid conflict with the close button on smaller screens */
}
/* The navigation links inside the overlay */
.overlay a {
padding: 8px;
text-decoration: none;
font-size: 36px;
color: #818181;
display: block; /* Display block
instead of inline */
transition: 0.3s; /* Transition
effects on hover (color) */
}
/*
When you mouse over the navigation links, change their color */
.overlay
a:hover, .overlay a:focus {
color:
#f1f1f1;
}
/* Position the close button (top right corner) */
.overlay .closebtn {
position:
absolute;
top: 20px;
right:
45px;
font-size: 60px;
}
/* When the height of the screen is less than 450 pixels, change the
font-size of the links and position the close button again, so they don't
overlap */
@media screen and (max-height: 450px) {
.overlay a {font-size: 20px}
.overlay .closebtn {
font-size: 40px;
top: 15px;
right: 35px;
}
}
Stap 3) Voeg JavaScript by:
Die voorbeeld hieronder gly in die oorlegnavigasiekieslys van links na regs (0 tot 100% breedte), wanneer dit geaktiveer word:
Skuif van die kant af in
/* Open
when someone clicks on the span element */
function openNav() {
document.getElementById("myNav").style.width
= "100%";
}
/* Close when someone clicks on the "x"
symbol inside the overlay */
function closeNav() {
document.getElementById("myNav").style.width = "0%";
}
Die voorbeeld hieronder gly in die oorlegnavigasiekieslys af van bo af (0 tot 100% hoogte).
Let wel: Let op in hierdie voorbeeld dat die CSS effens verskil van die een hierbo (verstek hoogte is nou 0, breedte is 100% en oorloop-y is versteek (deaktiveer vertikale blaai, behalwe vir klein skerms)):
Gly van bo af af
/* Open */
function openNav() {
document.getElementById("myNav").style.height
= "100%";
}
/* Close */
function closeNav() {
document.getElementById("myNav").style.height = "0%";
}
Hierdie voorbeeld maak die navigasiekieslys oop sonder animasie:
Maak die spyskaart oop sonder animasie
/* Open */
function openNav() {
document.getElementById("myNav").style.display
= "block";
}
/* Close */
function closeNav() {
document.getElementById("myNav").style.display = "none";
}
