Css text surround

I used to see the effect of css text surrounding pictures on Sina, but I couldn't understand it myself. I went to ask a front-end colleague and now I realized it was so simple, here are two examples.:

I. In html format

<Div align = "left">
· Www .111cn.net <br>
· Www .111cn.net <br>
· Www .111cn.net <br>
· Www .111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net
</Div>

Second:

Write style in head

<Style>

Dt {float: right ;}

</Style>

<Div> <dl>

<Dt> </dt>

<Dd>

Www.111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br>
· Www .111cn.netwww.111cn.net <br> </dd>

</Dl>

</Div>

After reading the above, I think it is very simple,
