我尝试使用repeating-linear-gradient选项设置border-image和background属性,但同一个<div>元素使用不同的值。我不知道怎么做,因为在我的尝试中,渐变参数似乎是重叠的,而且页面似乎也采用了最后设置的值。
下面是我得到的代码和输出:
body {
margin: 0;
background:
linear-gradient(217deg, rgba(255,0,0, .8), rgba(255,0,0,0) 70.71%),
linear-gradient(127deg, rgba(0,255,0, .8), rgba(0,255,0,0) 70.71%),
linear-gradient(336deg, rgba(0,0,255, .8), rgba(0,0,255,0) 70.71%);
}
.under_banner {
width: 100%;
height: 20%;
top: 80%;
border-width: 10px 0 0 0;
border-style: solid;
border-image: repeating-linear-gradient(145deg, #ff0000, #ff9020 50%);
background: repeating-linear-gradient(130deg, #f6d808, #ffc107 10%);
text-align: center;
line-height: 10px;
position: fixed;
z-index: 1;
}<body>
<div class="under_banner">
<p>Hello StackOverflow Community!</p>
</div>
</body>

如您所见,.under_banner具有top-border属性,实际上repeating-linear-gradient与background不对称。如果可能的话,我想用一个div为每个属性得到不同的渐变。
提前谢谢你!

您可以使用多个背景:
body {
background:
linear-gradient(217deg, rgba(255,0,0, .8), rgba(255,0,0,0) 70.71%),
linear-gradient(127deg, rgba(0,255,0, .8), rgba(0,255,0,0) 70.71%),
linear-gradient(336deg, rgba(0,0,255, .8), rgba(0,0,255,0) 70.71%);
}
.under_banner {
width: 100%;
left:0;
height: 20%;
bottom:0;
background:
repeating-linear-gradient(130deg, #f6d808, #ffc107 10%) bottom/100% calc(100% - 10px),
repeating-linear-gradient(145deg, #ff0000, #ff9020 50%);
background-repeat:no-repeat;
text-align: center;
line-height: 10px;
position: fixed;
z-index: 1;
}<body>
<div class="under_banner">
<p>Hello StackOverflow Community!</p>
</div>
</body>
或者像下面这样调整您的代码,您只是缺少了slice属性:
body {
background:
linear-gradient(217deg, rgba(255,0,0, .8), rgba(255,0,0,0) 70.71%),
linear-gradient(127deg, rgba(0,255,0, .8), rgba(0,255,0,0) 70.71%),
linear-gradient(336deg, rgba(0,0,255, .8), rgba(0,0,255,0) 70.71%);
}
.under_banner {
width: 100%;
left:0;
height: 20%;
bottom:0;
border-width: 10px 0 0 0;
border-style: solid;
border-image: repeating-linear-gradient(145deg, #ff0000, #ff9020 50%) 10; /* added the slice here */
background: repeating-linear-gradient(130deg, #f6d808, #ffc107 10%);
text-align: center;
line-height: 10px;
position: fixed;
z-index: 1;
}<body>
<div class="under_banner">
<p>Hello StackOverflow Community!</p>
</div>
</body>
