虚线渐变靠背景色，设置边框为白色，然后背景色渐变。之后中间的content 是白色背景
<div style="border-right: 1px dashed #fff;background: linear-gradient(to right, rgb(0, 255, 127),rgba(26, 115, 232, 0.953)); background-origin: border-box; width:577px;"><div style="font-size: 16px; background-color:#fff;">虚线渐变</div></div>
实现渐变靠的是设置边框渐变
border-width: 1px 0px 0px 10px; border-color: rgb(0, 255, 127);border-style: solid; border-image:linear-gradient(to right,rgb(0, 255, 127),rgba(26, 115, 232, 0.953)) 1 10;"
