如何使用漸變色條紋邊框通過CSS創建矩形？

Question

我想要創建圓邊條矩形漸變條紋邊條紋。

我想用IMG標籤或DIV標籤，包括圖像和漸變條紋邊框。

這是怎麼了，需要的樣子：

我嘗試搜索周圍，我發現（SCSS）例如：https://jsfiddle.net/rami7250/yujsz7wf/

和我得到這個SCSS代碼：

.module { 
    background: white; 
    border: 1px solid #ccc; 
    margin: 3%; 
    > h2 { 
    padding: 1rem; 
    margin: 0 0 0.5rem 0; 
    } 
    > p { 
    padding: 0 1rem; 
    } 
    /*animation: widen 10s linear alternate infinite;*/ 
} 

.stripe-1 { 
    color: white; 
    background: repeating-linear-gradient(
    45deg, 
    #606dbc, 
    #606dbc 10px, 
    #465298 10px, 
    #465298 20px 
); 
} 

正如您所看到的，該功能隻影響背景而不是邊界。

如何作出這樣的矩形，以顯示他的邊框漸變彩色條紋通過CSS/SCSS？

Answer 1

一種選擇是將linear-gradient以所需模式使用爲background-image，並將所需內容放在此背景之上。只要內容（無論是圖像還是任何文本或任何不需要透明的內容）都可以使用此方法。輸出也可以通過懸停在元素上來看到。

只需條：（白色層被放置在梯度的頂部，只顯示條）同內部圖像

div { 
 
    height: 250px; 
 
    width: 400px; 
 
    background: linear-gradient(white, white), 
 
       linear-gradient(60deg, orange 0%, orange 3.5%, white 3.5%, white 7%, hotpink 7%, hotpink 10.5%, black 10.5%, black 14%, brown 14%, brown 17.5%, aqua 17.5%, aqua 21%, green 21%, green 25%, orange 25%, orange 28.5%, white 28.5%, white 32%, hotpink 32%, hotpink 35.5%, black 35.5%, black 39%, brown 39%, brown 42.5%, aqua 42.5%, aqua 46%, green 46%, green 50%, orange 50%, orange 53.5%, white 53.5%, white 57%, hotpink 57%, hotpink 60.5%, black 60.5%, black 64%, brown 64%, brown 67.5%, aqua 67.5%, aqua 71%, green 71%, green 75%, orange 75%, orange 78.5%, white 78.5%, white 82%, hotpink 82%, hotpink 85.5%, black 85.5%, black 89%, brown 89%, brown 92.5%, aqua 92.5%, aqua 96%, green 96%, green 100%); 
 
    padding: 10px 20px; 
 
    border-radius: 20px; 
 
    background-origin: content-box, padding-box; 
 
    background-clip: content-box, padding-box; 
 
} 
 

 
/* just for demo */ 
 

 
div { 
 
    transition: all 1s; 
 
} 
 
div:hover { 
 
    height: 300px; 
 
    width: 500px; 
 
}

<div></div>

div：

div { 
 
    height: 250px; 
 
    width: 400px; 
 
    background: linear-gradient(white, white), linear-gradient(60deg, orange 0%, orange 3.5%, white 3.5%, white 7%, hotpink 7%, hotpink 10.5%, black 10.5%, black 14%, brown 14%, brown 17.5%, aqua 17.5%, aqua 21%, green 21%, green 25%, orange 25%, orange 28.5%, white 28.5%, white 32%, hotpink 32%, hotpink 35.5%, black 35.5%, black 39%, brown 39%, brown 42.5%, aqua 42.5%, aqua 46%, green 46%, green 50%, orange 50%, orange 53.5%, white 53.5%, white 57%, hotpink 57%, hotpink 60.5%, black 60.5%, black 64%, brown 64%, brown 67.5%, aqua 67.5%, aqua 71%, green 71%, green 75%, orange 75%, orange 78.5%, white 78.5%, white 82%, hotpink 82%, hotpink 85.5%, black 85.5%, black 89%, brown 89%, brown 92.5%, aqua 92.5%, aqua 96%, green 96%, green 100%); 
 
    padding: 10px 20px; 
 
    border-radius: 20px; 
 
    background-origin: content-box, padding-box; 
 
    background-clip: content-box, padding-box; 
 
} 
 
img { 
 
    height: 250px; 
 
    width: 400px; 
 
} 
 
/* just for demo */ 
 

 
div, img { 
 
    transition: all 1s; 
 
} 
 
div:hover, div:hover img { 
 
    height: 300px; 
 
    width: 500px; 
 
}

<div> 
 
    <img src='http://lorempixel.com/400/250/nature/1' /> 
 
</div>

隨着重複線性梯度：（感謝vals用於創建演示）

div { 
 
    height: 250px; 
 
    width: 400px; 
 
    background: linear-gradient(white,white), repeating-linear-gradient(60deg, orange 0%, orange 3.5%, white 3.5%, white 7%, hotpink 7%, hotpink 10.5%, black 10.5%, black 14%, brown 14%, brown 17.5%, aqua 17.5%, aqua 21%, green 21%, green 25%); 
 
    background-attachment: padding-box, border-box; 
 
    padding: 10px 20px; 
 
    border-radius: 20px; 
 
    background-origin: content-box, padding-box; 
 
    background-clip: content-box, padding-box; 
 
} 
 

 
/* just for demo */ 
 

 
div { 
 
    transition: all 1s; 
 
} 
 
div:hover { 
 
    height: 300px; 
 
    width: 500px; 
 
}

<div> 
 
</div>

注：的jagg ed邊緣是使用傾斜漸變時難以避免的東西。它們可以通過調整顏色停止點來減少。

Answer 2

發現可能是該設計的關鍵的東西。在這裏看到：https://jsfiddle.net/rami7250/jaca7sb4/

這裏是代碼的來源：http://codepen.io/SitePoint/pen/DKhkf

CSS：

div { 
    position: relative; 
    height: 100%; 

} 
div:before, div:after { 
    position: absolute; 
    content: ''; 
    height: 1em; 
    top: 0; 
    left: 0; 
    right: 0; 
} 
div:after { 
    top: auto; 
    bottom: 0; 
} 
div:before { 
    background: linear-gradient(90deg, #1abc9c 1%, #2ecc71 1%, #2ecc71 29%, #3498db 29%, #3498db 32%, #9b59b6 32%, #9b59b6 37%, #34495e 37%, #34495e 53%, #f1c40f 53%, #f1c40f 69%, #e67e22 69%, #e67e22 67%, #e74c3c 67%, #e74c3c 74%, #ecf0f1 74%, #ecf0f1 100%, #95a5a6 100%); 
} 
div:after { 
    background: linear-gradient(90deg, #1abc9c 10%, #2ecc71 10%, #2ecc71 12.5%, #3498db 12.5%, #3498db 28%, #9b59b6 28%, #9b59b6 35%, #34495e 35%, #34495e 60%, #f1c40f 60%, #f1c40f 69%, #e67e22 69%, #e67e22 83%, #e74c3c 83%, #e74c3c 88%, #ecf0f1 88%, #ecf0f1 96%, #95a5a6 96%); 
} 

div { 
    padding-top: 20px; 
    width: 450px; 
} 

但是，我不能將其設置在右和離開側的div。只有頂部和底部有效。

沒有必要爲這是如此令人費解，它需要CSS的兩行：

.module { 
    border: 20px solid; 
    border-image: repeating-linear-gradient(45deg,#606dbc,#606dbc 10px,#465298 10px,#465298 20px) 20; 
}
