I have been racking my brain for the past hour trying to get my HTML file to display what I'm adding. This is an example of my code :
@import url('https://fonts.googleapis.com/css2?family=Fredoka&family=Rubik:wght@300&display=swap');
html {
    height: 100%;
}
body {
    margin: 0;
}
/* Header that contains logo, horizontal navigation, and lists. */
.container {
    width: 80%;
    height: 200px;
    margin: 0;
}
header {
    font-family: 'Rubik', sans-serif;
    font-weight: 300;
    background-color: rgb(31,150,196);
    background-image: linear-gradient(160deg, rgba(31,150,196,1) 0%, rgba(52,165,175,1) 50%, rgba(173,225,230,1) 100%);
}
header::after {
    content: '';
    display: table;
    clear: both;
}
.logo {
    float: left;
    padding: 50px 15px 30px 150px;
    width: 550px;
    height: 200px;
}
nav {
    float: left;
    
}
nav ul {
    margin: 0;
    padding: 70px 15px 15px 15px;
    list-style: none;
    font-weight: 500;
    font-size: 25px;
}
nav li {
    display: inline-block;
    margin-left: 70px;
    padding-top: 30px;
    position: relative;
}
nav a {
    color: #ffffff;
    text-decoration: none;
    text-transform: uppercase;
}
nav a::before {
    content: '';
    display: block;
    height: 5px;
    width: 100%;
    background-color: #ffffff;
    position: absolute;
    top: 0;
    width: 0;
    transition: all ease-in-out 200ms;
}
nav a:hover::before {
    width: 100%;
}
/* Header that contains logo, horizontal navigation, and lists. End. */
/* Sidebar. */
* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
    list-style: none;
    text-decoration: none;
    font-family: 'Rubik', sans-serif;
}
.wrapper {
    display: flex;
    position: relative;
}
.wrapper .sidebar {
    position: fixed;
    width: 200px;
    height: 100%;
    background: #b9b9b9;
    padding : 35px 0;
}
.wrapper .sidebar h2 {
    color: #ffffff;
    text-transform: uppercase;
    text-align: center;
    margin-bottom: 30px;
    font-size: 35px;
}
.wrapper .sidebar ul li {
    padding: 25px;
}
.wrapper .sidebar ul li a {
    color: #1A5276;
    display: block;
    font-size: 20px;

    <h1>Hello</h1>
</body>
</html>The problem arises when I'm adding more content to the page in the HTML file, specifically the h1 tag that has Hello inside it. Even when I had Live Server turned on on my VSCode, it still will not update anything to the browser. I have tried closing and opening the browser twice, I even closed my VSCode and opened it again but it still will not update anything. I have restarted my computer, I tried to open the html on Internet Explorer and it's still not updating the h1 tag that I added. Before turning off my computer I have saved the code but it was fine, just a normal save. Plus, I even tried to make a new html with just the word hello wrapped in a h1 tag, that worked. But not my previous code.
Before you guys ask, I have looked through the questions of the same problem on here but nothing really applies to my problem. I have never had this happened before and I do not want to restart writing my code. The reason I added the CSS in here also is because I cannot, for the life of me, figure out what went wrong.
I went through this question :
Why is my HTML file not displaying to the browser?
and the answers have not helped.
Any replies will be greatly appreciated and I thank you very much for taking the time to help me out on this matter.
