Helloo!
I think for this we need to see all code, not just header
Also, do you have this whole thing on codepen?
That would be necessary for this issue I guess
@admit8490 Here’s my whole code below…

yep, just a sec) Some strange stuff was in another thread)
I guess we have case-sensitivity related issues here.
You don’t need to rush, you know) We don’t have deadlines here 
@admit8490 Well after changing the id of “features” to lower case it passed the challenge for me… Thank you so much for bringing my notice to that because i couldn’t even figure that’s where the problem is coming from lol…One more thing please, i can’t seem to pass this challenge…
Your “#nav-bar” should always be at the top of the viewport.
Here you want to do research about position property. MDN and w3s both have relevant content if I remember correctly.
Well, I don’t know if order matters here… To pass the tests you don’t need additional styling tho, only this positon stuff if I am not mistaken
Yeah but if i’m gonna add the position property, i gotta style it in CSS
Yeah, of course. To pass this tests you need little bit of CSS
Okay thank you so much…I already have the codes in html, now i gotta style it in CSS…Can i have your email handle or number so we could exchange ideas or hit you up when i have a problem…
Create a thread here if you have a problem, you can get help from more experienced people than me, you know)
That’s a bit personal stuff, not sharing it here.
You know my codepen, right? You can write some stuff in comments to any of my pens, I check it regularly
That’s my github
I’m not on github…Anyways if you don’t wanna share that with me no worries…You can share & delete it immediately but it’s up to you…
Nothing personal, man. I just have some rules in terms of behaviour on the web.
I suggest you to start with github, it’s important to my opinion
It’s okay no worries…I’ve got codepen, why do i need github??
