w3-mobile | Adds mobile-first responsiveness to any element. Displays elements as block elements on mobile devices |
<div class="w3-display-container w3-green" style="height:300px;">
<div class="w3-display-topleft">Top Left</div>
<div class="w3-display-topright">Top Right</div>
<div class="w3-display-bottomleft">Bottom Left</div>
<div class="w3-display-bottomright">Bottom Right</div>
<div class="w3-display-left">Left</div>
<div class="w3-display-right">Right</div>
<div class="w3-display-middle">Middle</div>
<div class="w3-display-topmiddle">Top Mid</div>
<div class="w3-display-bottommiddle">Bottom Mid</div>
</div>
Same example as above with added padding:
<div class="w3-display-container w3-green" style="height:300px;">
<div class="w3-padding w3-display-topleft">Top Left</div>
<div class="w3-padding w3-display-topright">Top Right</div>
<div class="w3-padding w3-display-bottomleft">Bottom Left</div>
<div class="w3-padding w3-display-bottomright">Bottom Right</div>
<div class="w3-padding w3-display-left">Left</div>
<div class="w3-padding w3-display-right">Right</div>
<div class="w3-padding w3-display-middle">Middle</div>
<div class="w3-padding w3-display-topmiddle">Top Mid</div>
<div class="w3-padding w3-display-bottommiddle">Bottom Mid</div>
</div>
Displaying text inside an image:
<div class="w3-display-container">
<img src="img_lights.jpg" alt="Lights" style="width:100%">
<div class="w3-padding w3-display-topleft">Top Left</div>
<div class="w3-padding w3-display-topright">Top Right</div>
<div class="w3-padding w3-display-bottomleft">Bottom Left</div>
<div class="w3-padding w3-display-bottomright">Bottom Right</div>
<div class="w3-padding w3-display-topmiddle">Top Mid</div>
<div class="w3-padding w3-display-left">Left</div>
<div class="w3-padding w3-display-right">Right</div>
<div class="w3-padding w3-display-middle">Middle</div>
<div class="w3-padding w3-display-bottommiddle">Bottom Mid</div>
</div>
The w3-display-hover class displays content on hover inside a w3-display-container (goes from hidden to shown).
<div class="w3-display-container w3-light-grey" style="height:300px;">
<div class="w3-display-topleft w3-display-hover">Top Left</div>
<div
class="w3-display-topright w3-display-hover">Top Right</div>
<div
class="w3-display-bottomleft w3-display-hover">Bottom Left</div>
<div class="w3-display-bottomright w3-display-hover">Bottom Right</div>
<div class="w3-display-left w3-display-hover">Left</div>
<div
class="w3-display-right w3-display-hover">Right</div>
<div
class="w3-display-middle">Mouse over this box!</div>
<div
class="w3-display-topmiddle w3-display-hover">Top Mid</div>
<div
class="w3-display-bottommiddle w3-display-hover">Bottom Mid</div>
</div>
The w3-display-hover classes can be combined with effect and animation classes to create cool hover effects:
<div class="w3-display-container w3-hover-opacity">
<img src="img_avatar.png"
alt="Avatar">
<div class="w3-display-middle w3-display-hover">
<button class="w3-button
w3-black">John Doe</button>
</div>
</div>
You will learn more about animations and effects later in this tutorial.
With a little bit of imagination, the w3-display-classes can be used to create a flag:
<div class="w3-display-container w3-card-4" style="height:200px;width:350px">
<div class="w3-red w3-display-topleft" style="width:25%;height:40%"></div>
<div class="w3-red w3-display-topright" style="width:60%;height:40%"></div>
<div class="w3-red w3-display-bottomleft" style="width:25%;height:40%"></div>
<div class="w3-red w3-display-bottomright" style="width:60%;height:40%"></div>
</div>
The w3-left class floats an element to the left, the w3-right class floats an element to the right:
<div class="w3-bar w3-light-grey">
<div class="w3-left
w3-red">w3-left</div>
<div class="w3-right w3-blue">w3-right</div>
</div>
Note: Clear floats with the w3-clear class or put them inside a w3-container, like in the example above (clears floats automatically).
Force an element to be shown or hidden with the w3-show or w3-hide class.
<p class="w3-show">I am shown (display: block).</p>
<p class="w3-hide">I am hidden (display: none).</p>
These classes are often used to toggle between hiding and showing elements:
function myFunction() { var x = document.getElementById("Demo"); if (x.className.indexOf("w3-show") == -1) { x.className += " w3-show"; } else { x.className = x.className.replace(" w3-show", ""); } }
Hello!
The w3-mobile class adds mobile-first responsiveness to any element.
It adds display:block and width:100% to an element on screens that are less than 600px wide.
<button class="w3-button w3-mobile">Link</button>
