如何使用線性漸變顏色創建按鈕邊框和文本？

Question

我有一個半圓形的按鈕。但我不知道如何將它彎曲以便在邊框處使用我的半圓形按鈕。

.semi-circle { 
    display:  inline-block; 
    padding:  9px 16px; 
    border-radius: 999px !important; 
    text-align: center; 

    /*border: 10px solid transparent;*/ 
    /* -moz-border-image: -moz-linear-gradient(right, #FC913A 0%, #FF4E50 100%); 
    -webkit-border-image: -webkit-linear-gradient(right, #FC913A 0%, #FF4E50 100%); 
    border-image: linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
    /*border-image-slice: 1;*/ 
border: linear-gradient(to right, green 0%, blue 100%); 

/*background-image: linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
background-image: -o-linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
background-image: -moz-linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
background-image: -webkit-linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
background-image: -ms-linear-gradient(to left, #FC913A 0%, #FF4E50 100%);*/ 
*/ 
} 

請原諒，我不能夠嵌入由於缺乏信譽的形象。 Thx爲堆棧溢出社區提供了卓越的服務。

可能有更好的方法來做到這一點，但沒有進一步的思考我想嘗試這樣的：

<style type="text/css"> 
.semi_outer { 
    padding: 2px; 
    text-align: center; 
    border-radius: 11px; 
    background: linear-gradient(to right, #0f0, #00f); 
} 

.semi_inner { 
    margin: 2px; 
    border-radius: 7px; 
    background-color: #000; 
    color: #0f0; 
} 

.semi_outer:hover { 
    background: linear-gradient(to right, #c00, #0c0); 
} 

.semi_outer:active { 
    background: linear-gradient(to right, #f00, #0f0); 
} 
</style> 

<div class="semi_outer"> 
    <div class="semi_inner"> 
    semi_inner 
    </div> 
</div>

這是你的半圓形按鈕。可能會對你有幫助。

.outer { 
 
    padding: 2px; 
 
    text-align: center; 
 
    border-radius: 11px; 
 
    background: linear-gradient(to right, #0f0, #00f); 
 
    width: 200px; 
 
    height:30px; 
 
} 
 

 
.inner { 
 
    margin: 3px; 
 
    border-radius: 7px; 
 
    background-color: #000; 
 
    color: #0f0; 
 
    height:25px; 
 
} 
 

 
.outer:hover { 
 
    background: linear-gradient(to right, #c00, #0c0); 
 
} 
 

 
.outer:active { 
 
    background: linear-gradient(to right, #f00, #0f0); 
 
}

<div class="outer"> 
 
    <div class="inner"> 
 
     BUTTON 
 
    </div> 
 
</div>

這裏是溶液。它在webkit中運行良好。在其他瀏覽器中，文本顏色是穩定的。

HTML

<button data-text="Round button"></button> 
<button class="active" data-text="Active round button"></button> 

CSS

    background: #384041;

*:before, 
*:after {
