Question

<p align="center">
This is a text.
<hr width="30px" align="right" align="left" />
</p>

Answer 1

I think it should be read from left to right and the attribute align ="left" must be apply to html. Anyone think so.

Answer 2

I"ll try it on pc once again. I'm not sure how it work.

Answer 3

Because you put align="right" first then align="left" and program is confused then. You must delete align="right".

Answer 4

No, it is reading from left line 30 pixels if you delete align="right, otherwise it is reading from right line 30 pixels
