我在 HTML 文档中遇到 CSS 背景渐变问题。我设计了一个使用线性渐变作为背景的页面，并将其设置在 body 元素上。我面临的问题是，渐变似乎在屏幕最初结束的地方结束，即使有更多内容需要滚动。因此，当您向下滚动时，渐变的第二个实例似乎会重新开始。

这是我当前的 CSS (SCSS) 代码：

@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);
}

预期的行为是渐变始终覆盖整个屏幕，包括最初不可见的内容，因为必须滚动到它。我想避免有两个渐变实例。本质上，渐变应该适应屏幕的高度，甚至滚动的高度。

我尝试使用不同的 CSS 属性和值，例如 height: auto;最小高度：100%；但这些似乎不起作用。我也尝试过不重复，但它的作用是显示一个写入矩形。任何帮助，将不胜感激！ 以下是 HTML，以防您需要它来重现错误：
