A basic W3CSS Modal

There are three basic components of a Modal. A source that when interacted fires an event that opens a Modal. This source can be a button or link or whatever you want. Next thing is a div or element with class “w3-modal” this div is the container for the modal. The source is linked with this div. Inside this div there is another element or div with class “w3-modal-content” class. This class contains the actual modal content.

Now we have to devise a mechanism to connect the source that fires the event and the modal. Let’s do it with the help of an example.In the following example, we have div. The onclick event of the div executes a function which displays the modal with id “Modal1” as block level element. Similarly, the next div is the modal div with id “Modal1”. Inside the modal div, there is a cross button which when clicked closes the model window by setting its display property to none. Take a look at the following code snippet to see a modal in action.

  <div onclick="document.getElementById('Modal1').style.display='block'" class="w3-blue w3-xlarge">Click to open Modal</div>

  <div id="Modal1" class="w3-modal">
    <div class="w3-modal-content">
      <div class="w3-container">
