What i’m trying to accomplish:
HTML:
<body>
<h3 class="fancy">Head3<h3>
<p class="fancy">paragraph</p>
<p id="serious">para2</p>
<p>Brianna</p>
</body>
CSS:
body :nth-child(4) {
font-size: 26px;
}
Result:
Oops, try again. Did you give your third paragraph a font-size of 26px? It looks like it’s currently undefined.
Why am I getting this error message, is there something wrong with my code?
Thanks for the help in advance 
Hey @brianna_vaykeas_com! Its the pargraph your suppose to set it. So codecademy dosent know what to set to 26px.
So instead of this(whitch is not defined ) :
Do this:
body p:nth-child(4) {Thanks @amanuel2 - this causes the desired effect to the 3rd paragraph, but i’m still getting the error message that will not let me save and move on. I suspect this may be a bug… 
screen shot your window. Will you?
Oh Sorry! I forgot put it as the fourth element not the third since its one more. This will surely solve your problem
unfortunately, everything i have tried is resulting in the same . My code clearly works because the font size is indeed increasing on the preview page, not sure why i can’t save and submit code
Type in 4 and take a screen shot.(sorry im making you take a lot of screenshots). But i need a Mod to look at this so they can fix it or identify your problems

Try body:nth-child(4). From the instructions, that seems to be what the grader is hinting at.
This is because p has no children. p itself is a child, but it is not a parent of anything but the text.
Ok, my bad.
Try this:
p:nth-child(3) { font-size: 26px; } (spacing as necessary)
but ALSO, go to your browser’s zoom settings to make sure they aren’t zoomed in. To quickly see if you’re zoomed it, press the key combination ctrl+0 to reset to 100%. An incorrect zoom can cause a grading glitch.
That h3 element needs a / in its closing tag.
