Can I make a similar animation only with CSS3

Question

I am working on a website and now I need to do the intro animation just like this http://www.elitemodel.fr/

On this website, when I load the page, the logo and backgroung are shifted to the left. My client wants this effect on his website.

I am currently creating an intro.php page with this html code:

<div class="intro">
    <div class="logo-intro"></div><!-- /.logo logo-intro -->
</div><!-- /.intro -->
<div class="black_overlay"></div><!-- /.logo logo-intro -->

I am trying to do this with css3 and a little javascript.

After html, this is my CSS code for the animation:

.intro,
.intro .logo-intro {
    overflow: hidden;
   -moz-animation: slide 2s ease 1.5s forwards;
   -webkit-animation: slide 2s ease 1.5s forwards;
   -o-animation: slide 2s ease 1.5s forwards;
   -ms-animation: slide 2s ease 1.5s forwards;
    animation: slide 2s ease 1.5s forwards;
}

@-moz-keyframes slide /* Firefox */
    {
        from {width: 100%; }
        to {width: 0;}
    }

@-webkit-keyframes slide /* Safari and Chrome */
    {
        from {width: 100%;}
        to {width: 0;}
    }

@-o-keyframes slide /* Opera */
    {
        from {background: white;}
        to {background: black;}
    }

@-ms-keyframes slide /* IE10 */
    {
        from {width: 100%;}
        to {width: 0;}
    }

@keyframes slide
    {
        from {width: 100%;}
        to {width: 0;}
    }

}

.logo-intro  {
    -webkit-animation: logo 1s;  /* Chrome, Safari, Opera */
    -webkit-animation-iteration-count: 2;  /* Chrome, Safari, Opera */
    -webkit-animation-fill-mode: forwards;  /* Chrome, Safari, Opera */
    animation: logo 1s;
    animation-iteration-count: 2;
    animation-fill-mode: forwards;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes logo {
    from {top: 50%;}
    to {left: -99999px;}
}

@keyframes logo {
    from {top: 50%;}
    to {left: -99999px;}
}

After the animation finishes, I redirect intro.php to the home page using javascript

// Your application has indicated there an error
window.setTimeout(function(){
// Move to a new location or you can do something else
var url = "http://www.gaelscalpaesthetics.com/accueil";    
$(location).attr('href',url);
}, 4000);

This works, but how can I make this animation without redirecting?
