This page outlines both methods and explains the pros and cons of each method.
You can create scrolling text using the HTML
<marquee> tag. Below is an example of using the HTML
<marquee> tag to create scrolling text.
See HTML Scrolling Text for more examples.
This method is nice and easy to implement—you can create scrolling text with a single line of code. The
<marquee> tag is supported by the major browsers.
The main disadvantage of the
<marquee> tag is that it's non-standard HTML. It is not actually included in the official HTML specifications. This is mainly because the marquee effect is more suited towards Cascading Style Sheets (CSS). CSS animations were introduced in CSS3 and allow you to create scrolling text and other animated effects. Therefore, CSS looks like the way of the future for scrolling text.
animation property and
@keyframes rule allow us to create scrolling text (not to mention other, more advanced, animated effects).
Creating scrolling text with CSS is a little more involved, however, you have a wider range of options available to you.
The following example creates a similar result to the above method, but as you can see, it requires a lot more code. Don't be put off by this though. The following code uses browser prefixes to ensure that the text scrolls correctly in various browsers, however, it's pretty safe to remove these prefixes, as most browsers now support CSS animations without prefixes.

CSS scrolling text...
While CSS animations are a little more complex to learn and code than HTML marquees, they do provide a powerful means of animating the various HTML elements on the page. They are also being implemented into the CSS specifications (as from CSS3) and therefore, if you want your code to be standards-compliant, then you will need to use the CSS method.
