Here I found 6 websites that you can create animation online:
use godaddy
You can create a website using an HTML editor software. These are available online for free. The one I use is KompoZer. You can also create a website using WordPress for free at WordPress.org
Wordpress.
flash
Flash is a basic and easy to use animation software. Anyone with little knowledge of animation can easily create a good & attractive animation on Flash.
Autocad can be used to create 3D models. Not the best to use for animation though. For animation and using Autodesk programs, I would suggest using 3DS Max. There are many free tutorials online to help with 3DS Max.
It is a site that helps you to create a professional website and also provides you with the online space. And yes, it is free to use. However there are also options you can use but only if you pay for it.
Try to use some sitebuilders. You can find them in Google
i have no idea.how should i know?i am just a kid!
They most likely didn't use a website to make theirs they probably hired a professional to create it from scratch if you wanted to create a website like roblox then I can make it for you but it will not be free just email me at jdd148@yahoo.com
If a free website is what is needed then the best free website builder is definitely webstarts.com. The tools are easy to use and the options are pretty cool and they have lots of templates to use.
You can learn how to use a free 3D animation program like Blender. A simple intro with just text and a background should be fairly easy to create.
