  <img src="img_avatar.png" alt="Avatar">
  <div class="w3-display-middle w3-display-hover">

  </div>

Displaying A Flag

With a little bit of imagination, the w3-display-classes can be used to create a flag:

Example

<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>

Floating Classes

The w3-left class floats an element to the left, the w3-right class floats an element to the right:

w3-left
w3-right

Example

<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).


Hide and Show

Force an element to be shown or hidden with the w3-show or w3-hide class.

Example

<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:

It adds display:block and width:100% to an element on screens that are less than 600px wide.
