Why is a floating box outside its container?
This code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ><TITLE ></TITLE > <BLOCKQUOTE STYLE="BACKGROUND: YELLOW; HEIGHT: 10EX" ><P STYLE="FLOAT: RIGHT" >Lorem<HR ><P STYLE="FLOAT: RIGHT" >ipsum</BLOCKQUOTE >
- Why is BLOCKQUOTE wider than HR?
- Why is ‘Lorem’ aligned with the widened BLOCKQUOTE?
- Why is ‘ipsum‘ not aligned likewise?

To achieve what you want, you have to add some clearing DIV elements or CSS rules.
data:text/html;charset=utf-8, <!doctype html public "-//w3c//dtd html 4.01//en"> <head> <title></title> </head> <body> <blockquote style="background: yellow;" > <p style="float: right;" >Lorem</p> <hr style="clear: both;" > <p style="float: right;" >ipsum</p> <div style="clear: both;"></div> </blockquote> </body>Прочетете този отговор в контекста 👍 0

Well, not quite the code I intended…
Maybe this will work:
< !DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" >< TITLE >< /TITLE > < BLOCKQUOTE STYLE="BACKGROUND: YELLOW; HEIGHT: 10EX" >< P STYLE="FLOAT: RIGHT" >Lorem< HR >< P STYLE="FLOAT: RIGHT" >ipsum< /BLOCKQUOTE >

Or this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ><TITLE ></TITLE > <BLOCKQUOTE STYLE="BACKGROUND: YELLOW; HEIGHT: 10EX" ><P STYLE="FLOAT: RIGHT" >Lorem<HR ><P STYLE="FLOAT: RIGHT" >ipsum</BLOCKQUOTE >

What is ‘!doctype’?
I think that:
- the rule is being shortened by ‘Lorem’ because its margin overlaps it,
- ‘ipsum’ is lower than ’Lorem’ because of the margin under the rule,
- ‘ipsum’ is to the left of ‘Lorem’ because the margin under the rule is too narrow.
Correct me if I am wrong. I have probably missed two important points:
- a float can shorten a rule,
- margins around a float do not collapse.
Thank you,

Floats within a container do not make that container adjust its width and height to fit the floats unless you use a clear rule.
So in your case the P elements float, but the HR element doesn't and is rendered first (your code looks the same in Google Chrome as in Firefox).
If you need a more precise explanation about how floats work then it is best to ask advice at the MozillaZine "Web Development/Standards Evangelism" forum.
The helpers at that forum are more knowledgeable about web development issues.
