"See it to believe it" lesson


I am stuck in the lesson titled "See it to believe it". The lesson is asking to draw borders around every HTML elment using the universal selector. So I entered in the CSS the following:
* {
border: 1px dashed #0000FF;

I keep getting the following error message "Oops, try again. It looks like your border-width isn't 1px.". Can you tell me what I am doing wrong?

Therefor it is of an advantage to know that you have 2 reset facilities:

One is the use of the F5-key which does a refresh Browser


Two, select&copy your code
Then use the Reset Code button of the course-window,
then paste your code back in.

General Notes:
Always refresh the browser after making corrections:
CTRL f5 ( if on Windows or Linux)
CMD r ( if on a MAC).
CTRL 0 to reset browser zoom


Thank you. CTRL 0 fixed the problem.
