Html – blank space on top and left of the page while developing frontend

I am building an application in Django and for writing templates I am using HTML/CSS, now there is some weird white space I am encountering on the top and left side of the page which does not go, no matter what I try as shown below

now here are my css files

base.css

.navbar {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 60px;
    display: flex;
    align-items: center;
    justify-content: space-between;
    background-color: #333;
    color: white;
    padding: 10px 20px;
    z-index: -1;
}

.navbar-brand img {
    max-height: 40px;
}

.navbar-menu ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    display: flex;
}

.navbar-menu li {
    margin: 0 10px;
}

.navbar-menu li a {
    color: white;
    text-decoration: none;
}

.navbar-user img {
    max-height: 30px;
}

and home.css

.home-video {
    position: relative;
    width: 100vw;
    height: 100vh;
    overflow: hidden;
    z-index: -1;
}

#bg-video {
    width: 100vw;
    height: 100vh;
    object-fit: cover;
}

.home-content {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    text-align: center;
}

.home-content h1 {
    font-size: 3rem;
    margin-bottom: 20px;
    color: white;
}

.home-content p {
    font-size: 1.2rem;
    margin-bottom: 30px;
    color: white;
}

.btn {
    display: inline-block;
    padding: 10px 20px;
    background-color: #333;
    color: white;
    text-decoration: none;
    border-radius: 5px;
    transition: background-color 0.3s ease;
}

.btn:hover {
    background-color: #555;
}
