I'm having trouble with CSS background gradients in my HTML document. I designed a page that uses a linear gradient as the background and sets it on the body element. The problem I'm facing is that the gradient seems to end where the screen initially ends, even though there is more content to scroll. So when you scroll down, the second instance of the gradient appears to start over.

This is my current CSS (SCSS) code: 

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@400;500;700&display=swap');


body {
    min-height: 100vh;
    background: linear-gradient(to bottom, rgb(10, 25, 47), rgb(44, 83, 100));
    color: whitesmoke;
    font-family: 'Poppins', sans-serif;
}


img {
    max-width: 28%;
    border-radius: 50%;
}

.container {
    height: auto;
    width: 100vw;
    height: 100vh;
    display: grid;
    grid-template-columns: repeat(2, 1fr);
    grid-template-rows: 1fr 0.25fr 3fr;
    gap: 3%;
    padding: 3%;
    box-sizing: border-box;
}

.content-left, .content-right {
    display: flex;
    align-items: center;
    justify-content: center;
}

.slogan {
    grid-column: span 2;
    font-size: 1.5em;
    display: flex;
    align-items: top;
    justify-content: center;
    text-transform: uppercase;
    letter-spacing: 2px;
}
.container-form {
    height: auto;
    grid-column: span 2;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    margin-bottom: 30px; // Add space at the bottom
}


input, textarea, select {
    border: 2px solid whitesmoke;
    background-color: rgba(255, 255, 255, 0.1);
    color: whitesmoke;
}

input:invalid:not(:placeholder-shown), textarea:invalid:not(:placeholder-shown) {
    border: 2px solid red;
}

input:invalid:focus:not(:placeholder-shown), textarea:invalid:focus:not(:placeholder-shown) {
    outline: none;
}

input:invalid:not(:placeholder-shown)::placeholder, textarea:invalid:not(:placeholder-shown)::placeholder {
    color: red;
}

#register-form:invalid:not(:placeholder-shown) ~ #popup {
    display: block;
}

button, input[type=submit] {
    margin-top: 20px;
    padding: 10px 20px;
    font-size: 1em;
    transition: background-color 0.3s ease;
}

button:hover, input[type=submit]:hover {
    background-color: rgba(255, 255, 255, 0.1);
}

.form-container {
    background: rgba(255, 255, 255, 0.1);
    border-radius: 15px;
    padding: 20px;
    width: 100%;
    max-width: 400px;
    box-sizing: border-box;
}

.form-control {
    background-color: transparent !important;
    color: whitesmoke !important;
    border-color: whitesmoke;
}

.form-control::placeholder {
    color: rgba(255, 255, 255, 0.7);
}

.button-container {
    display: flex;
    justify-content: space-between;
    gap: 10px;
    width: 100%;
}

#login-button {
    background-color: transparent;
    border: 2px solid whitesmoke;
    color: whitesmoke;
}

#login-button:hover {
    background-color: rgba(255, 255, 255, 0.1);
}

The expected behavior is that the gradient always covers the entire screen, including content that is not initially visible because one has to scroll to it. I want to avoid having two gradient instances. Essentially, the gradient should adapt to the height of the screen and even the height of the scroll.

I tried using different CSS properties and values ​​such as height: auto;min-height:100%;but these don't seem to work. I also tried without repeating but what it does is it displays a write rectangle. Any help would be greatly appreciated! Here's the HTML in case you need it to reproduce the error:

For this problem, just include the background-repeat and background-attachment properties as no-repeat and fixed代码>. Then, set the height attribute of the html and body tags to 100%. Similar answers
