CSS-moving text from left to right - css

Question

I want to create an animated HTML "marquee" that scrolls back and forth on a website:
<div class="marquee">This is a marquee!</div>
and the CSS:
.marquee {
position: absolute;
white-space: nowrap;
-webkit-animation: rightThenLeft 4s linear;
}
#-webkit-keyframes rightThenLeft {
0% {left: 0%;}
50% {left: 100%;}
100% {left: 0%;}
}
The problem is, the marquee doesn't stop when it reaches the right-hand edge of the screen; it moves all the way off the screen (making a horizontal scroll bar appear, briefly) and then comes back.
So, how do I make the marquee stop when its right-hand edge reaches the right-hand edge of the screen?
EDIT: Oddly, this does not work:
50% {right: 0%}

Answer 1

Somehow I got it to work by using margin-right, and setting it to move from right to left.

Don't know why for this case, margin-right 100% doesn't go off the screen. :D
(tested on chrome 18)
EDIT: now left to right works too http://jsfiddle.net/6LhvL/

Answer 2

You could simply use CSS animated text generator. There are pre-created templates already

Answer 3

Hi you can achieve your result with use of <marquee behavior="alternate"></marquee>
HTML
<div class="wrapper">
<marquee behavior="alternate"><span class="marquee">This is a marquee!</span></marquee>
</div>
CSS
.wrapper{
max-width: 400px;
background: green;
height: 40px;
text-align: right;
}
.marquee {
background: red;
white-space: nowrap;
-webkit-animation: rightThenLeft 4s linear;
}
see the demo:- http://jsfiddle.net/gXdMc/6/

Answer 4

I like using the following to prevent things being outside my div elements. It helps with CSS rollovers too.
.marquee{
overflow:hidden;
}
this will hide anything that moves/is outside of the div which will prevent the browser expanding and causing a scroll bar to appear.

Answer 5

If I understand you question correctly, you could create a wrapper around your marquee and then assign a width (or max-width) to the wrapping element. For example:
<div id="marquee-wrapper">
<div class="marquee">This is a marquee!</div>
</div>
And then #marquee-wrapper { width: x }.

I am not sure if this is the correct solution but I have achieved this
by redefining .marquee class just after animation CSS.
Check below:
<style>
#marquee-wrapper{
width:700px;
display:block;
border:1px solid red;
}
div.marquee{
width:100px;
height:100px;
background:red;
position:relative;
animation:myfirst 5s;
-moz-animation:myfirst 5s; /* Firefox */
}
#-moz-keyframes myfirst /* Firefox */{
0% {background:red; left:0px; top:0px;}
100% {background:red; left:100%; top:0px}
}
div.marquee{
left:700px; top:0px
}
</style>
<!-- HTMl COde -->
<p><b>Note:</b> This example does not work in Internet Explorer and Opera.</p>
<div id="marquee-wrapper">
<div class="marquee"></div>
