Why does my browser keep on ignoring my CSS Class?

August 28, 2022

i have been trying my best to understand why my browser keeps ignoring my css class. If i open the file path on my computer it looks just as it should, but when i put it into the hosting by FTP it shows it without the classes
My HTML:

<!-- FOOTER -->
<div class="divfooter">
    <img src="Images/shs-logo.png" alt="shs-logo" class="infooter">
    <img src="Images/Rooseveltka-logo.png" alt="rooseveltka-logo" class="infooter">
    <img src="Images/Logo_szu.png" alt="szu-logo" class="infooter">
    <img src="Images/upjs-LOGO.png" alt="upjs-logo" class="infooter">
    <p class="madeby">Built by Goli Golo</p>
</div>

<head>
<title>SIRIUS</title>

<style>
body,h1,h2,h3,h4,h5 {font-family: "Poppins", sans-serif}
body {font-size:16px;}
.w3-half img{margin-bottom:-6px;margin-top:16px;opacity:0.8;cursor:pointer}
.w3-half img:hover{opacity:1}
</style>
</head>

My CSS:

.divfooter {
    width: 100%;
    height: auto;
    background-color: lightgrey;
    display: inline-flex;
    justify-content: flex-end;
    align-items: center;
    gap: 3%;
}

.infooter {
    padding: 4px;
    max-width: 5%;
    justify-content: center;
}

.madeby {
    padding-right: 5%;
    justify-content: flex-start;
}

Every help will be hugely appreciated, i have been trying to figure it out last 2 days and cannot get my mind around it. If anything more is need i will hapily provide.
Thanks in advance,
Richarddddd.
