I have linked the website on the github, but when I click on the Gallery button it does not go to the gallery page, it works fine when i open it locally on my pc. I have updated new repository again and was trying to find the bug but I dont know what is wrong. Link to the page on my github: https://maciejrakowski1987.github.io/Smarthome-new-project/
the code looks fine to me:
<div class="col">
<img src="img/galeriaIcon.png">
<h2>Galeria</h2>
<p>Kliknij aby zobaczyć galerie: </p>
<a class="btn-second" href="gallery.html">dowiedz się więcej</a>
</div>
all the other links work fine.
Your html file in github has its first letter uppercase'd. And in the code you have it in lowercase. You should change
<a class="btn-second" href="gallery.html">dowiedz się więcej</a>
to
<a class="btn-second" href="Gallery.html">dowiedz się więcej</a>
