JS documentation project - fails the 4th test

I have problem with passing 4th test and i dont know why it fails. Link to pen = https://codepen.io/BlazikeNFront/pen/vYGxKBB?editors=1100.

<section class = 'main-section' id='if...else statement' >

You can’t have an id with dots and spaces.


Thanks for help, but actually dot was not a problem . There was one missing underscore in id… so it was space…
P.S i think that you can use dots in id because when you check example from freeCodeCamp https://codepen.io/freeCodeCamp/full/NdrKKL - there are dots in that section, anyway thanks for help :slight_smile:
