CSS3 button with a creative hover effect.

CSS3 Button Hover Effect Deconstructed

My recent research confirmed that 99.9% of websites have at least one button. Interesting right?

But how many sites actually have a more creative hover effects than the standard color change or fade between two colors? Not many.

You can stand out from the crowd and implement some creative hover effects like the one from Omnisense Experience.

Let’s have a look at how it was done.

1. Initial state

<div class="btn skip">
  <span class="hover-bg reset">
    <span class="hover-text reset">Skip</span>
  </span>
  Skip
</div>

Surprisingly the markup for this button isn’t a link as you would expect (our CodePen demo is using a).

I am sure the authors had a reason for that.

The html consists of a .btn container which has two span elements inside of it .hover-bg and .hover-text.

Both of these inner elements have also a .reset class, that defines the initial position of the hover state.

.btn {
  height: 51px;
  min-width: 218px;
  color: #3b7fe0;
  font-size: 18px;
  font-weight: 400;
  line-height: 51px;
  text-transform: uppercase;
  display: inline-block;
  border: 1px solid #3b7fe0;
  position: relative;
  overflow: hidden;
  text-decoration: none;
  text-align: center;
  cursor: pointer;
}

.btn .hover-text {
  color: #fff;
  opacity: 1;
  position: absolute;
  left: 55%;
  opacity: 0;
  transform: skew(42deg) translateX(-39px);
}

.hover-text.reset {
  left: 55%;
  opacity: 0;
}

.btn .hover-bg {
  display: block;
  background-color: #3b7fe0;
  width: 122%;
  height: 102%;
  position: absolute;
  transform: skew(-42deg);
  left: -133%;
  top: 0;
  z-index: 4;
  overflow: hidden;
}

.hover-bg.reset {
  left: -133%;
  transition: none;
}

.hover-bg.reset is the state when the hover background is out of the view to the left.

.hover-bg has skew(-42deg) which creates the angled effect on the full color background rectangle, but we also need to include skew(42deg) on the .hover-text to straighten up the text.

Two additional classes enter and leave define the position of the ‘hover’ elements.

.enter – animates in from the left

.leave – animates out to the right

2. Animation in – Enter

.hover-text.enter {
  left: 50%;
  opacity: 1;
  transition: left 0.5s cubic-bezier(0.19, 1, 0.22, 1), opacity 0.5s;
}

.hover-bg.enter {
  left: -11%;
  transition: left 0.5s cubic-bezier(0.19, 1, 0.22, 1);
}

.enter is the state when we animate the left property from the original value to a new one over the duration of 0.3s.

Note: I’ve removed all vendor prefixes from the code example to simplify it for us.

3. Animation out – Leave

.hover-text.leave {
  left: 100%;
  opacity: 0;
  transition: left 0.5s cubic-bezier(0.19, 1, 0.22, 1) 0.3s, opacity 0.5s;
}

.hover-bg.leave {
  left: 111%;
  transition: left 0.5s cubic-bezier(0.19, 1, 0.22, 1);
}

.leave is the state when we animate the hover elements out of the view to the right.

This is again accomplished by animating the left offset to 100% and 111% values.

4. Toggle CSS classes using jQuery

The Omnisense Experience example uses Greensock for the animations, but we could replicate a similar effect with jQuery.

Similar to the CSS3 Preloading screen tutorial, we will use jQuery to generate the extra classes.

In a simple terms we want to remove .reset, add a class .enter when the user hovers over the button.

Then we remove .enter and add .leave when the mouse leaves the button.

And finally after a 500ms delay we want to remove .leave and return to the original position by adding back the class .reset.

The jQuery code would look something like this.

var hoverSpan = $('.btn span');

$( ".btn" ).mouseenter(function() {
    //remove reset and add enter on hover  
    $(hoverSpan).removeClass('reset').addClass('enter');
  
  })
  .mouseleave(function() {
    //remove enter and add leave
    
    $(hoverSpan).removeClass('enter').addClass('leave');
    
    //remove leave and add reset after 500ms delay
    setTimeout(function() {
      $(hoverSpan).removeClass('leave').addClass('reset');
    }, 500);

});

Explore the source code in the CodePen demo to see the final result.
