I use AddThis for share buttons. But what is shared are links, no text. What am I doing wrong?

I know about W3schools, thanks for this one, I will check it out

You will find some help online. What me helped even today sometimes is SelfHTML . org

Yes, I guess I wasn't clear about that, I'm still relatively new in HTML

I thought you wanted to mark a text and share it, but you mean the titel and the description from the website.

I found the problem. I needed to have the tag called "title" in the "head" of the page. I checked a page at APSense by clicking View Source, I saw it, I edited my page, then clicked on the FB share button, it works.

That isn't possible. You share just the link.

Of course I want the link to be there too, but I want it to grab some text on the page.

well i juts downloaded it and it works on mine bottom and top

As far as i know is AddThis for sharing the page URL where the button is to several networks. Never heard that you could share with it just a text block.
