CSS 背景漸層不會覆蓋整個頁面（包括可捲動內容）

我在 HTML 文件中遇到 CSS 背景漸層問題。我設計了一個使用線性漸層作為背景的頁面，並將其設定在 body 元素上。我面臨的問題是，漸變似乎在螢幕最初結束的地方結束，即使有更多內容需要滾動。因此，當您向下滾動時，漸變的第二個實例似乎會重新開始。

這是我目前的 CSS (SCSS) 程式碼：

@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);
}

預期的行為是漸變始終覆蓋整個螢幕，包括最初不可見的內容，因為必須滾動到它。我想避免有兩個漸變實例。本質上，漸層應該適應螢幕的高度，甚至滾動的高度。

我嘗試使用不同的 CSS 屬性和值，例如 height: auto;最小高度：100%；但這些似乎不起作用。我也嘗試過不重複，但它的作用是顯示一個寫入矩形。任何幫助，將不勝感激！ 以下是 HTML，以防您需要它來重現錯誤：

對於此問題，只需將background-repeat 和background-attachment 屬性包含為no-repeat 和fixed代码>.然後，將html 和body 標記的height 屬性設為100%。 類似答案

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@400;500;700&display=swap');
html {
  height: 100%;
}
