在Bootstrap 4中重新着色工具提示 [英] Re-color Tooltip in Bootstrap 4

问题描述

我正在尝试对Bootstrap 4中的工具提示进行换肤/重新格式化，而原来的操作方法似乎不再起作用.目前，我正在这样做:

I'm trying to re-skin/re-format a tooltip in Bootstrap 4, and the original way of doing it doesn't seem to work anymore. Currently I am doing this:

.tooltip-inner {
    background: #7abcff; 
    background: -webkit-linear-gradient(top, #7abcff 0%,#60abf8 44%,#4096ee 100%); 
    background:    -moz-linear-gradient(top, #7abcff 0%,#60abf8 44%,#4096ee 100%); 
    background:   linear-gradient(to bottom, #7abcff 0%,#60abf8 44%,#4096ee 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#7abcff', endColorstr='#4096ee',GradientType=0 ); 
    color: #fff;
    font-family: 'Roboto', Arial, sans-serif;
}
.tooltip.top .tooltip-arrow {
    border-top-color: #7abcff;
}

.tooltip-inner可以正常工作，但.tooltip.top .tooltip-arrow不能正常工作；它保持黑色.我假设.tooltip.top是底部对齐的工具提示上方的箭头.

.tooltip-inner is working fine, but .tooltip.top .tooltip-arrow isn't; it stays black. I am assuming .tooltip.top is the arrow on top of a bottom aligned tooltip.

任何帮助将不胜感激

推荐答案

从Bootstrap 4.0

CSS 用于工具提示的重新着色由您注意到的.tooltip-inner类处理:

CSS for tooltip recoloring is handled by the .tooltip-inner class as you noticed:

.tooltip-inner {
    max-width: 200px;
    padding: 3px 8px;
    color: #fff;
    text-align: center;
    background-color: #000;
    border-radius: .25rem;
}

顶部箭头的css:

.tooltip.bs-tooltip-auto[x-placement^=top] .arrow::before, .tooltip.bs-tooltip-top .arrow::before {
    margin-left: -3px;
    content: "";
    border-width: 5px 5px 0;
    border-top-color: #000;
}

右箭头的:

Css for right arrow:

.tooltip.bs-tooltip-auto[x-placement^=right] .arrow::before, .tooltip.bs-tooltip-right .arrow::before {
    margin-top: -3px;
    content: "";
    border-width: 5px 5px 5px 0;
    border-right-color: #000;
}

底部箭头的CSS:

.tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .tooltip.bs-tooltip-bottom .arrow::before {
    margin-left: -3px;
    content: "";
    border-width: 0 5px 5px;
    border-bottom-color: #000;
}

左箭头的CSS:

.tooltip.bs-tooltip-auto[x-placement^=left] .arrow::before, .tooltip.bs-tooltip-left .arrow::before {
    right: 0;
    margin-top: -3px;
    content: "";
    border-width: 5px 0 5px 5px;
    border-left-color: #000;
}
