It looks like I did not understandand the following instruction;
You should use the existing margin property to include 1em on the top and bottom.
Here is my iterpretation
border-color: white; min-width: 300px; margin: 10px1em 0 0 1em;
This is my whole code;
input[type=“submit”] {
display: block;
width: 60%;
height: 2em;
font-size: 1.1rem;
background-color: #3b3b4f;
border-color: white; min-width: 300px; margin: 10px1em 0 0 1em;
Hi there!
Can you insert your full code and link to project here for clarity? You can insert your code with three backticks (`) on a separate line before and after your code. 
I’m not sure what this step is asking, but when you add a margin you can only have 4 different numbers, max. You have 5.

}
the last line of the css code there is what i am not getting it right, specifically the margin part.
the instruction was;
Lastly, for the submit button, you want to separate it from the fieldset above, and adjust its width to never be below 300px.
Change the margin property to include 1em on the top and bottom, while leaving the right and left margins set to auto. Then set the width as described above.
may thoutght was to give this;
border-color: white; min-width: 300px; margin: 1em 0 0 1em;
Kindly check though the full code and let me know what i should do right.
Thaks a lot.

Great! I see what you’re saying. First, step 60 is asking for you to set your right and left margin to “auto” so take a look at your value again. Second, here is the value for margins:
4 values: top, right, bottom, left
3 values: top, right AND left, bottom
2 values: top AND bottom, left AND right
1 value: all margins
Since your top and bottom margins and left and right margins are the same, you don’t need 4 values. Hope this helps! 
Wonderful Morgan, now it is very clear to me, more than I had before…
Thanks a lot.
Awesome, glad I could help!
