Creating original hover effects using CSS3


image

The power of CSS3 is enormous and in this tutorial we will see how to exploit it in a very creative way. We are going to create some thumbnail hover effects with CSS3 transitions. On hover over a thumbnail, we will reveal some description of the thumbnail, using a different style in each example.

Please note that this will only work properly in modern browsers that support the CSS3 properties in use.

HTML markup


The structure of markup is very simple and intuitive. Create a container that will have our image and all the other information.

Inside the view insert an element with the class mask that will be responsible for our effects driven by CSS3 and inside it we will put a title, description and a link to the full image. (For some examples, we’ll need to add the mask element as a separate element and wrap the description in a devi with class content.)

<div class="view">

<div class="mask">
<h2>Title</h2>
<p>Your Text</p>
<a class="info" href="#">Read More</a>
</div>
</div>

CSS


After creating our markup we’re going to set our style.

We set the general rules for our class and then we are going to add a special class with the desired effect styles. We will omit the CSS3 vendor prefixes when showing the style.

view {
width: 300px;
height: 200px;
margin: 10px;
float: left;
border: 10px solid #fff;
overflow: hidden;
position: relative;
text-align: center;
box-shadow: 1px 1px 2px #e6e6e6;
cursor: default;
background: #fff url(../images/bgimg.jpg) no-repeat center center
}
.view .mask, .view .content {
width: 300px;
height: 200px;
position: absolute;
overflow: hidden;
top: 0;
left: 0
}
.view img {
display: block;
position: relative
}
.view h2 {
text-transform: uppercase;
color: #fff;
text-align: center;
position: relative;
font-size: 17px;
padding: 10px;
background: rgba(0, 0, 0, 0.8);
margin: 20px 0 0 0
}
.view p {
font-family: Georgia, serif;
font-style: italic;
font-size: 12px;
position: relative;
color: #fff;
padding: 10px 20px 20px;
text-align: center
}
.view a.info {
display: inline-block;
text-decoration: none;
padding: 7px 14px;
background: #000;
color: #fff;
text-transform: uppercase;
box-shadow: 0 0 1px #000
}
.view a.info:hover {
box-shadow: 0 0 5px #000
}

And now we’ll look at the ten effects.

Example 1

image

We Add the special class view-first to the element with the class view for this effect. We will be adding a special class to each example’s view element (view-first, view-second, view-third, etc.).

<div class="view view-first">

</div>

In this first example we will just use some basic transitions to create a nice hover effect:

.view-first img {
transition: all 0.2s linear;
}
.view-first .mask {
opacity: 0;
background-color: rgba(219,127,8, 0.7);
transition: all 0.4s ease-in-out;
}
.view-first h2 {
transform: translateY(-100px);
opacity: 0;
transition: all 0.2s ease-in-out;
}
.view-first p {
transform: translateY(100px);
opacity: 0;
transition: all 0.2s linear;
}
.view-first a.info{
opacity: 0;
transition: all 0.2s ease-in-out;
}
Now here comes the heart of our effect. When you move the mouse over the image, we can use the delay property to emulate simple animations. The transition-delay that we use in the hover class can be altered, to be different than the one in the normal class. In this example we did not use any delay in the normal class; but we added a delay on hover, which will make the transition start a bit later. Moving the mouse out, the default value of 0s will apply and the “reverse” will be quicker.

.view-first:hover img {
transform: scale(1.1);
}
.view-first:hover .mask {
opacity: 1;
}
.view-first:hover h2,
.view-first:hover p,
.view-first:hover a.info {
opacity: 1;
transform: translateY(0px);
}
.view-first:hover p {
transition-delay: 0.1s;
}
.view-first:hover a.info {
transition-delay: 0.2s;
}

Example 2

image

In this second example we will add the special class view-second, but we will leave the element with the class mask empty and wrap the description in a div with the class content.

<div class="view view-second">

<div class="mask"></div>
<div class="content">
<h2>Hover Style #2</h2>
<p>Some description</p>
<a class="info" href="#" >Read More</a>
</div>
</div>

Here the mask class will have different attributes to satisfy our effect, in fact we are going to apply the transform property (translate and rotate) and will make a square out of it. The description elements will be translated, i.e. moved so that we can slide them in on hover:

.view-second img {
transition: all 0.2s ease-in;
}
.view-second .mask {
background-color: rgba(115,146,184, 0.7);
width: 300px;
padding: 60px;
height: 300px;
opacity: 0;
transform: translate(265px, 145px) rotate(45deg);
transition: all 0.2s ease-in-out;
}
.view-second h2 {
border-bottom: 1px solid rgba(0, 0, 0, 0.3);
background: transparent;
margin: 20px 40px 0px 40px;
transform: translate(200px, -200px);
transition: all 0.2s ease-in-out;
}
.view-second p {
transform: translate(-200px, 200px);
transition: all 0.2s ease-in-out;
}
.view-second a.info {
transform: translate(0px, 100px);
transition: all 0.2s 0.1s ease-in-out;
}
For our hover effect we exploit the translate transformation in order to move our elements in place. The mask will also be rotated. The elements of the description will each come with a little delay:

.view-second:hover .mask {
opacity:1;
transform: translate(-80px, -125px) rotate(45deg);
}
.view-second:hover h2 {
transform: translate(0px,0px);
transition-delay: 0.3s;
}
.view-second:hover p {
transform: translate(0px,0px);
transition-delay: 0.4s;
}
.view-second:hover a.info {
transform: translate(0px,0px);
transition-delay: 0.5s;
}

Example 3

image

In this third example we will use the translate and rotate transforms to bring up our content:

.view-third img {
transition: all 0.2s ease-in;
}
.view-third .mask {
background-color: rgba(0,0,0,0.6);
opacity: 0;
transform: translate(460px, -100px) rotate(180deg);
transition: all 0.2s 0.4s ease-in-out;
}
.view-third h2{
transform: translateY(-100px);
transition: all 0.2s ease-in-out;
}
.view-third p {
transform: translateX(300px) rotate(90deg);
transition: all 0.2s ease-in-out;
}
.view-third a.info {
transform: translateY(-200px);
transition: all 0.2s ease-in-out;
}
These are the simple instructions that are applied on hover. Now we will reverse the appearing of the description elements by setting the transition-delay accordingly:

.view-third:hover .mask {
opacity:1;
transition-delay: 0s;
transform: translate(0px, 0px);
}
.view-third:hover h2 {
transform: translateY(0px);
transition-delay: 0.5s;
}
.view-third:hover p {
transform: translateX(0px) rotate(0deg);
transition-delay: 0.4s;
}
.view-third:hover a.info {
transform: translateY(0px);
transition-delay: 0.3s;
}

Example 4

image

Here in the fourth example we will perform a simple zoom out image and a zoom in of our content with rotation, all thanks to the scale transform. We set the transition-delay to 0.2s for the image style, but on hover we’ll say that it’s 0s. This will make it start immediately on hover, but delay it on mouse out.

.view-fourth img {
transition: all 0.4s ease-in-out 0.2s;
opacity: 1;
}
.view-fourth .mask {
background-color: rgba(0,0,0,0.8);
opacity: 0;
transform: scale(0) rotate(-180deg);
transition: all 0.4s ease-in;
border-radius: 0px;
}
.view-fourth h2{
opacity: 0;
border-bottom: 1px solid rgba(0, 0, 0, 0.3);
background: transparent;
margin: 20px 40px 0px 40px;
transition: all 0.5s ease-in-out;
}
.view-fourth p {
opacity: 0;
transition: all 0.5s ease-in-out;
}
.view-fourth a.info {
opacity: 0;
transition: all 0.5s ease-in-out;
}
These are the simple instructions to get the effect – with CSS3 you can do everything :)

.view-fourth:hover .mask {
opacity: 1;
transform: scale(1) rotate(0deg);
transition-delay: 0.2s;
}
.view-fourth:hover img {
transform: scale(0);
opacity: 0;
transition-delay: 0s;
}
.view-fourth:hover h2,
.view-fourth:hover p,
.view-fourth:hover a.info{
opacity: 1;
transition-delay: 0.5s;
}
Example 5

image

In this fifth example we will use the translate property along with the transition-timing-function ease-in-out in order to slide the content in from the left.

.view-fifth img {
transition: all 0.3s ease-in-out;
}
.view-fifth .mask {
background-color: rgba(146,96,91,0.3);
transform: translateX(-300px);
opacity: 1;
transition: all 0.4s ease-in-out;
}
.view-fifth h2{
background: rgba(255, 255, 255, 0.5);
color: #000;
box-shadow: 0px 1px 3px rgba(159, 141, 140, 0.5);
}
.view-fifth p{
opacity: 0;
color: #333;
transition: all 0.2s linear;
}
The hover effect will make the image slide to the right and the description come from the left, as if it’s pushing the image:

.view-fifth:hover .mask {
transform: translateX(0px);
}
.view-fifth:hover img {
transform: translateX(300px);
transition-delay: 0.1s;
}
.view-fifth:hover p{
opacity: 1;
transition-delay: 0.4s;
}
Example 6

image

In this example we will make the description come from the front, zooming out until its original size (scale from factor 10 to 1). The info button will slide in from the bottom (translate).

.view-sixth img {
transition: all 0.4s ease-in-out 0.5s;
}
.view-sixth .mask{
background-color: rgba(146,96,91,0.5);
opacity:0;
transition: all 0.3s ease-in 0.4s;
}
.view-sixth h2{
opacity:0;
border-bottom: 1px solid rgba(0, 0, 0, 0.3);
background: transparent;
margin: 20px 40px 0px 40px;
transform: scale(10);
transition: all 0.3s ease-in-out 0.1s;
}
.view-sixth p {
opacity:0;
transform: scale(10);
transition: all 0.3s ease-in-out 0.2s;
}
.view-sixth a.info {
opacity:0;
transform: translateY(100px);
transition: all 0.3s ease-in-out 0.1s;
}
The reverse transition will be delayed in such a way that it looks smooth:

.view-sixth:hover .mask {
opacity:1;
transition-delay: 0s;
}
.view-sixth:hover img {
transition-delay: 0s;
}
.view-sixth:hover h2 {
opacity: 1;
transform: scale(1);
transition-delay: 0.1s;
}
.view-sixth:hover p {
opacity:1;
transform: scale(1);
transition-delay: 0.2s;
}
.view-sixth:hover a.info {
opacity:1;
transform: translateY(0px);
transition-delay: 0.3s;
}
Example 7

image

In this seventh example the idea is to rotate the image to the center and scale it down. Then the description comes rotating from up with the description content following.

.view-seventh img{
transition: all 0.5s ease-out;
opacity: 1;
}
.view-seventh .mask {
background-color: rgba(77,44,35,0.5);
transform: rotate(0deg) scale(1);
opacity: 0;
transition: all 0.3s ease-out;
transform: translateY(-200px) rotate(180deg);
}
.view-seventh h2{
transform: translateY(-200px);
transition: all 0.2s ease-in-out;
}
.view-seventh p {
transform: translateY(-200px);
transition: all 0.2s ease-in-out;
}
.view-seventh a.info {
transform: translateY(-200px);
transition: all 0.2s ease-in-out;
}

On hover we add a delay for the desciption elements. This will show us the rotating image first and then the description will come into the picture. In the reverse transition, everything will disappear immediately and we’ll see the image rotate back:

.view-seventh:hover img{
transform: rotate(720deg) scale(0);
opacity: 0;
}
.view-seventh:hover .mask {
opacity: 1;
transform: translateY(0px) rotate(0deg);
transition-delay: 0.4s;
}
.view-seventh:hover h2 {
transform: translateY(0px);
transition-delay: 0.7s;
}
.view-seventh:hover p {
transform: translateY(0px);
transition-delay: 0.6s;
}
.view-seventh:hover a.info {
transform: translateY(0px);
transition-delay: 0.5s;
}

Example 8

image

In this eighth example we’ll use an animation and recreate a bounce effect. The description will bounce in from the top.

.view-eighth .mask {
background-color: rgba(255, 255, 255, 0.7);
top: -200px;
opacity: 0;
transition: all 0.3s ease-out 0.5s;
}
.view-eighth h2{
transform: translateY(-200px);
transition: all 0.2s ease-in-out 0.1s;
}
.view-eighth p {
color: #333;
transform: translateY(-200px);
transition: all 0.2s ease-in-out 0.2s;
}
.view-eighth a.info {
transform: translateY(-200px);
transition: all 0.2s ease-in-out 0.3s;
}
We will add the animation to the mask element and define some fitting delays for the onset of the description elements:

.view-eighth:hover .mask {
opacity: 1;
top: 0px;
transition-delay: 0s;
animation: bounceY 0.9s linear;
}
.view-eighth:hover h2 {
transform: translateY(0px);
transition-delay: 0.4s;
}
.view-eighth:hover p {
transform: translateY(0px);
transition-delay: 0.2s;
}
.view-eighth:hover a.info {
transform: translateY(0px);
transition-delay: 0s;
}

To recreate a true bounce effect we use the translateY, as you can see there are a couple of frames, in order to make the effect:

@keyframes bounceY {
0% { transform: translateY(-205px);}
40% { transform: translateY(-100px);}
65% { transform: translateY(-52px);}
82% { transform: translateY(-25px);}
92% { transform: translateY(-12px);}
55%, 75%, 87%, 97%, 100% { transform: translateY(0px);}
}

Example 9

image

In this example, we will use two mask elements to slide them in from the bottom right and the top left:

<div class="view view-ninth">

<div class="mask mask-1"></div>
<div class="mask mask-2"></div>
<div class="content">
<h2>Hover Style #9</h2>
<p>Some Text</p>
<a class="info" href="#">Read More</a>
</div>
</div>

Elements of masks will have a different translation and a transform origin. Also, we’ll set one to be aligned at the top and the other at the bottom:

.view-ninth .mask-1,.view-ninth .mask-2{
background-color: rgba(0,0,0,0.5);
height: 361px;
width: 361px;
background: rgba(119,0,36,0.5);
opacity: 1;
transition: all 0.3s ease-in-out 0.6s;
}
.view-ninth .mask-1 {
left: auto;
right: 0px;
transform: rotate(56.5deg) translateX(-180px);
transform-origin: 100% 0%;
}
.view-ninth .mask-2 {
top: auto;
bottom: 0px;
transform: rotate(56.5deg) translateX(180px);
transform-origin: 0% 100%;
}
.view-ninth .content{
background: rgba(0,0,0,0.9);
height: 0px;
opacity: 0.5;
width: 361px;
overflow: hidden;
transform: rotate(-33.5deg) translate(-112px,166px);
transform-origin: 0% 100%;
transition: all 0.4s ease-in-out 0.3s;
}
.view-ninth h2{
background: transparent;
margin-top: 5px;
border-bottom: 1px solid rgba(255,255,255,0.2);
}
.view-ninth a.info{
display: none;
}
The content will be styled in a way that it looks like as if it’s coming out as a tiny slice through the touching edges of the two masks:

.view-ninth:hover .content{
height: 120px;
width: 300px;
opacity: 0.9;
top: 40px;
transform: rotate(0deg) translate(0px,0px);
}
.view-ninth:hover .mask-1,
.view-ninth:hover .mask-2{
transition-delay: 0s;
}
.view-ninth:hover .mask-1{
transform: rotate(56.5deg) translateX(1px);
}
.view-ninth:hover .mask-2 {
transform: rotate(56.5deg) translateX(-1px);
}

We are setting the transition-delay for the masks in such a way, that when we hover, the transition happens instantly. But when moving out with the mouse, the delay will be longer, as if its “waiting” for the content to move back into the slot.

Example 10

image

In the last example, we will zoom in the image and make it fade out while bringing the descpription to the front. We can do that by using the scale transform and setting the opacity level:

.view-tenth img {
transform: scaleY(1);
transition: all 0.7s ease-in-out;
}
.view-tenth .mask {
background-color: rgba(255, 231, 179, 0.3);
transition: all 0.5s linear;
opacity: 0;
}
.view-tenth h2{
border-bottom: 1px solid rgba(0, 0, 0, 0.3);
background: transparent;
margin: 20px 40px 0px 40px;
transform: scale(0);
color: #333;
transition: all 0.5s linear;
opacity: 0;
}
.view-tenth p {
color: #333;
opacity: 0;
transform: scale(0);
transition: all 0.5s linear;
}
.view-tenth a.info {
opacity: 0;
transform: scale(0);
transition: all 0.5s linear;
}
On hover, we’ll simply scale the image up and fade it out by decreasing its opacity to 0:

.view-tenth:hover img {
transform: scale(10);
opacity: 0;
}
.view-tenth:hover .mask {
opacity: 1;
}
.view-tenth:hover h2,
.view-tenth:hover p,
.view-tenth:hover a.info{
transform: scale(1);
opacity: 1;
}

Conclusion


CSS3 has a really great potential for creating nice effects. Soon, we will hopefully be able to avoid the use of JavaScript for simple effects and rely 100% on CSS, in all browsers.

These experiments may inspire you for your projects.
