Hi @Emir-dev
This lesson is all about spacing and making your code look nice by following the best practices. You should make your code look (spacing wise only) like
<ul>
<li> Child Element 1 </li>
<li> Child Element 2 </li>
</ul>
Notice the two space indent on the child components . Yours has far more than 2 spaces. I suggest simply reseting the lesson and then retry to space them
