CSS3 Fade slider

CSS3 Fade slider

Today I would like to show you how to create nice and smooth css3 slider. It uses fade effect to switch between slides. Plus, you can use custom promo text for each slide. We will use basic UL-LI unordered list to make this slider. We don’t need to click anywhere to switch slides – everything is automatically (css3 animation).

So, lets start

Step 1. HTML

Html markup is very easy. There are four slides. Each slide consists of image (as background) and promo text in DIV. If you need – you always can add more slides here.

<div class="slides">
    <ul> <!-- slides -->
        <li><img src="images/pic1.jpg" alt="image01" />
            <div>Promo text #1</div>
        </li>
        <li><img src="images/pic2.jpg" alt="image02" />
            <div>Promo text #2</div>
        </li>
        <li><img src="images/pic3.jpg" alt="image03" />
            <div>Promo text #3</div>
        </li>
        <li><img src="images/pic4.jpg" alt="image04" />
            <div>Promo text #4</div>
        </li>
    </ul>
</div>

Step 2. CSS

Now, it’s time to define css styles for our slider. Here are styles for main slider element, inner slides and for promo titles:

/* fade slider */
.slides {
    height:300px;
    margin:50px auto;
    overflow:hidden;
    position:relative;
    width:900px;
}
.slides ul {
    list-style:none;
    position:relative;
}

/* keyframes #anim_slides */
@-webkit-keyframes anim_slides {
    0% {
        opacity:0;
    }
    6% {
        opacity:1;
    }
    24% {
        opacity:1;
    }
    30% {
        opacity:0;
    }
    100% {
        opacity:0;
    }
}
@-moz-keyframes anim_slides {
    0% {
        opacity:0;
    }
    6% {
        opacity:1;
    }
    24% {
        opacity:1;
    }
    30% {
        opacity:0;
    }
    100% {
        opacity:0;
    }
}

.slides ul li {
    opacity:0;
    position:absolute;
    top:0;

    /* css3 animation */
    -webkit-animation-name: anim_slides;
    -webkit-animation-duration: 24.0s;
    -webkit-animation-timing-function: linear;
    -webkit-animation-iteration-count: infinite;
    -webkit-animation-direction: normal;
    -webkit-animation-delay: 0;
    -webkit-animation-play-state: running;
    -webkit-animation-fill-mode: forwards;

    -moz-animation-name: anim_slides;
    -moz-animation-duration: 24.0s;
    -moz-animation-timing-function: linear;
    -moz-animation-iteration-count: infinite;
    -moz-animation-direction: normal;
    -moz-animation-delay: 0;
    -moz-animation-play-state: running;
    -moz-animation-fill-mode: forwards;
}

/* css3 delays */
.slides ul  li:nth-child(2), .slides ul  li:nth-child(2) div {
    -webkit-animation-delay: 6.0s;
    -moz-animation-delay: 6.0s;
}
.slides ul  li:nth-child(3), .slides ul  li:nth-child(3) div {
    -webkit-animation-delay: 12.0s;
    -moz-animation-delay: 12.0s;
}
.slides ul  li:nth-child(4), .slides ul  li:nth-child(4) div {
    -webkit-animation-delay: 18.0s;
    -moz-animation-delay: 18.0s;
}
.slides ul li img {
    display:block;
}

/* keyframes #anim_titles */
@-webkit-keyframes anim_titles {
    0% {
        left:100%;
        opacity:0;
    }
    5% {
        left:10%;
        opacity:1;
    }
    20% {
        left:10%;
        opacity:1;
    }
    25% {
        left:100%;
        opacity:0;
    }
    100% {
        left:100%;
        opacity:0;
    }
}
@-moz-keyframes anim_titles {
    0% {
        left:100%;
        opacity:0;
    }
    5% {
        left:10%;
        opacity:1;
    }
    20% {
        left:10%;
        opacity:1;
    }
    25% {
        left:100%;
        opacity:0;
    }
    100% {
        left:100%;
        opacity:0;
    }
}

.slides ul li div {
    background-color:#000000;
    border-radius:10px 10px 10px 10px;
    box-shadow:0 0 5px #FFFFFF inset;
    color:#FFFFFF;
    font-size:26px;
    left:10%;
    margin:0 auto;
    padding:20px;
    position:absolute;
    top:50%;
    width:200px;

    /* css3 animation */
    -webkit-animation-name: anim_titles;
    -webkit-animation-duration: 24.0s;
    -webkit-animation-timing-function: linear;
    -webkit-animation-iteration-count: infinite;
    -webkit-animation-direction: normal;
    -webkit-animation-delay: 0;
    -webkit-animation-play-state: running;
    -webkit-animation-fill-mode: forwards;

    -moz-animation-name: anim_titles;
    -moz-animation-duration: 24.0s;
    -moz-animation-timing-function: linear;
    -moz-animation-iteration-count: infinite;
    -moz-animation-direction: normal;
    -moz-animation-delay: 0;
    -moz-animation-play-state: running;
    -moz-animation-fill-mode: forwards;
}

You can see that I use two css3 animations here: anim_slides and anim_titles. First one is for separated slides, second one – for promo texts. In order to switch between slides – we change opacity of slides. For titles – we change Left position and opacity too.

Conclusion

That is all for today. We have just created new cool pure CSS3-based slider with Fade effect. I hope that you like it. Good luck!
