How can kids make their own free web pages?

Ok so I need to make a website just you know for fun.. Where I can put a little biography or whatever, customize it, add pics, and stuff like that. And it has to be a kid friendly website and when I say that I mean under the age of 13. Just you know a quick webpage and I say under the age of 13 because a lot of my friends will want to make a website too. And it has to be 100% free. No hidden fees or anything like that. And it doesn’t matter if it has pop-up adds because i won’t click on them anyway. I will be really grateful to a person who can answer my question! Thanks so much!
