CSS製作Web頁面條紋背景樣式的技巧分享

透過CSS中的linear-gradient主要就能顯示出不同方向的條紋效果,這裡我們就了解CSS製作Web頁面條紋背景樣式的技巧分享,需要的朋友可以參考下

# #一、橫向條紋
如下碼：

background: linear-gradient(#fb3 20%, #58a 80%)

上面程式碼表示整個圖片的上部分20%和下部分20%是對應的純色，只有中間的部分是漸層色。如果讓中間的部分逐漸縮小，當中間部分變成0即上下兩種顏色的七點和終點相同是，就沒有了漸變而變成了兩種顏色的色條:

background: linear-gradient(#fb3 50%, #58a 50%);

接下來可以透過設定背景的大小，讓背景高度變小且背景預設為repeat，從而出現條紋狀

background: linear-gradient(#fb3 50%, #58a 50%);   
background-size: 100% 30px;

我們可以不設定第二個顏色的起始位置，設定為0，則瀏覽器預設為接著上一個顏色開始：

background: linear-gradient(#fb3 30%, #58a 0);   
background-size:100% 30px;

這樣就形成了一個黃色佔30%藍色佔70%的條紋狀背景

也可以設定多種顏色，下方設定了三種顏色的條紋：

background: linear-gradient(#fb3 33.3%, #58a 0, #58a 66.6%,yellowgreen 0);   
background-size: 100% 45px;

# 二、垂直條紋

只需要在linear-gradient方法中加一個前綴即可。注意還需顛倒background-size長寬的設定

background: linear-gradient(to rightright, #fb3 50%, #58a 0);     
background-size:30px 100%;

#三、斜向條紋
可以透過修改background-size的值以及為linear-gradient添加角度來實現斜向的條紋：background: linear-gradient(45deg, #fb3 50%, #58a 0);    //讓背景的漸變帶有傾斜
background-size :30px 30px;   //每一塊小組成部分固定寬度和高度
但這樣做的結果是只會形成一小塊一小塊的斜線，而不是整體p的斜線，我們需要以四個小p為一組繪製斜線，加入linear-gradient中的顏色分解：

background: linear-gradient(45deg, #fb3 25%, #58a 0, #58a50%, #fb3 0, #fb3 75%, #58a 0);     
background-size:30px 30px;

四、使用repeat-linear-gradient
#對於斜線的背景繪製，使用repeat-linear-gradient方法更有效。使用此方法的時候，設定的顏色變化會自動重複直到鋪滿整個p。實例程式碼如下：

background: repeating-linear-gradient(45deg, #fb3, #58a 30px);

透過這種方式可以任意更改角度，而不會出現上中方法中的調節困難

background: repeating-linear-gradient(60deg, #fb3, #fb315px, #58a 0, #58a 30px);
(這個方法其實相當於將size的控制和gradient的控制合到了一起)
 

#五、關於顏色的設定
有時我們希望條紋背景的顏色之間是相近的顏色，但是如果手動設定這個顏色的#很不方便，也很難發現要選擇什麼樣的顏色。可以使用以下方法：

background: #58a;     
background-image: repeating-linear-gradient(30deg,     
hsla(0,0%,100%,.1),     
hsla(0,0%,100%,.1)15px,     
transparent 0,transparent 30px);

這種方法的原則是：指定背景中最深的顏色，條文中其他相近色用透明度進行調整

六、綜合實例
這裡效果圖一起放上來了，與下面的樣式一一對應：

.stripes {   
    height: 250px;   
    width: 375px;   
    float: left;   

    margin: 10px;   

    -webkit-background-size: 50px 50px;   
    -moz-background-size: 50px 50px;   
    background-size: 50px 50px; /* 控制条纹的大小 */

    -moz-box-shadow: 1px 1px 8px gray;   
    -webkit-box-shadow: 1px 1px 8px gray;   
    box-shadow: 1px 1px 8px gray;
