我找不到相关的任何相关信息,但我觉得很难接受它是不可行的。

如何自定义弹出窗口的箭头?我已经做了但是改变了类.arrow等等,但是弹出窗口的位置搞砸了。

那么,这样做的正确方法是什么?我找不到任何文件。

以下是我一直在使用的课程,到目前为止箭头看起来不对:

.popover {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1010;
    display: none;
    padding: 5px;
}

    .popover.top {
        margin-top: -5px;
    }

    .popover.right {
        margin-left: 5px;
    }

    .popover.bottom {
        margin-top: 5px;
    }

    .popover.left {
        margin-left: -5px;
    }

    .popover.top .arrow {
        bottom: 0;
        left: 50%;
        margin-left: -5px;
        border-left: 5px solid transparent;
        border-right: 5px solid transparent;
        border-top: 5px solid #000000;
    }

    .popover.right .arrow {
        top: 50%;
        left: 0;
        margin-top: -5px;
        border-top: 5px solid transparent;
        border-bottom: 5px solid transparent;
        border-right: 5px solid #000000;
    }

    .popover.bottom .arrow {
        top: 0px;
        left: 50%;
        margin-left: -5px;
        border-left: 9px solid transparent;
        border-right: 9px solid transparent;
        border-bottom: 19px solid #000000;
    }

    .popover.left .arrow {
        top: 50%;
        right: 0;
        margin-top: -5px;
        border-top: 5px solid transparent;
        border-bottom: 5px solid transparent;
        border-left: 5px solid #000000;
    }

    .popover .arrow {
        position: absolute;
        width: 0;
        height: 0;
    }

.popover-inner {
    padding: 3px;
    width: auto;
    overflow: hidden;
    background: #000000;
    background: rgba(0, 0, 0, 0.8);
    -webkit-box-shadow: 0 3px 7px rgba(0, 0, 0, 0.3);
    -moz-box-shadow: 0 3px 7px rgba(0, 0, 0, 0.3);
    box-shadow: 0 3px 7px rgba(0, 0, 0, 0.3);
}

.popover-title {
    padding: 9px 15px;
    line-height: 1;
    background-color: #252525;
    -webkit-border-radius: 3px 3px 0 0;
    -moz-border-radius: 3px 3px 0 0;
    border-radius: 3px 3px 0 0;
    background-color: rgba(37, 37, 37, 0.7);
    font-size: 14px;
    color: #7e7e7e;
}

.popover-content {
    padding: 14px;
    background-color: #252525;
    -webkit-border-radius: 0 0 3px 3px;
    -moz-border-radius: 0 0 3px 3px;
    border-radius: 0 0 3px 3px;
    -webkit-background-clip: padding-box;
    -moz-background-clip: padding-box;
    background-clip: padding-box;
    background-color: rgba(37, 37, 37, 0.7);
}

    .popover-content p, .popover-content ul, .popover-content ol {
        margin-bottom: 0;
    }

    .popover-content table {
        background: transparent;
    }

        .popover-content table td {
            border: 0px;
            background: transparent;
            color: #7e7e7e;
        }

箭头应指向红色方块 Arrow should be pointing to the red square

对于使用自定义style.css的人来简单地覆盖bootstrap而不重新编译LESS,你正在寻找的css规则是.popover.top > .arrow:after { border-top-color: yourColorHere; }来改变箭头的颜色。

Twitter Bootstrap基于Less

如果您想更改其箭头的外观,请使用bootstrap less variables来执行此操作。

// Tooltips and popovers
// -------------------------
@tooltipColor:            #fff;
@tooltipBackground:       #000;
@tooltipArrowWidth:       5px;
@tooltipArrowColor:       @tooltipBackground;

@popoverBackground:       #fff;
@popoverArrowWidth:       10px;
@popoverArrowColor:       #fff;
@popoverTitleBackground:  darken(@popoverBackground, 3%);

// Special enhancement for popovers
@popoverArrowOuterWidth:  @popoverArrowWidth + 1;
@popoverArrowOuterColor:  rgba(0,0,0,.25);

如果您使用的是Sass,请使用Sass Variables

遗憾的是TB-Customizer没有所有变量,因此您可能需要自己编译。

修改

好消息,新的Bootstrap 3 customizer现在提供了这些选项。

使用这些变量自定义工具提示:

@tooltip-max-width:       200px;
@tooltip-color:           #FFF;
@tooltip-bg:              #000;
@tooltip-opacity:         .9;
@tooltip-arrow-width:     5px;
@tooltip-arrow-color:     #000;

我无法调整popover边框粗细。为了调整这个,我将@popoverBorderThickness添加到popovers.less,只更改了那些行。我将整个文件包含在上下文中。

//
// Popovers
// --------------------------------------------------


.popover {
  position: absolute;
  top: 0;
  left: 0;
  z-index: @zindexPopover;
  display: none;
  max-width: 276px;
  padding: 1px;
  text-align: left; // Reset given new insertion method
  background-color: @popoverBackground;
  -webkit-background-clip: padding-box;
     -moz-background-clip: padding;
          background-clip: padding-box;
  border: @popoverBorderThickness solid @popoverOuterColor;
  .border-radius(6px);
  .box-shadow(0 5px 10px rgba(0,0,0,.2));

  // Overrides for proper insertion
  white-space: normal;

  // Offset the popover to account for the popover arrow
  &.top     { margin-top: -10px; }
  &.right   { margin-left: 10px; }
  &.bottom  { margin-top: 10px; }
  &.left    { margin-left: -10px; }
}

.popover-title {
  margin: 0; // reset heading margin
  padding: 8px 14px;
  font-size: 14px;
  font-weight: normal;
  line-height: 18px;
  background-color: @popoverTitleBackground;
  border-bottom: 1px solid darken(@popoverTitleBackground, 5%);
  .border-radius(5px 5px 0 0);

  &:empty {
    display: none;
  }
}

.popover-content {
  padding: 9px 14px;
}

// Arrows
//
// .arrow is outer, .arrow:after is inner

.popover .arrow,
.popover .arrow:after {
  position: absolute;
  display: block;
  width: 0;
  height: 0;
  border-color: transparent;
  border-style: solid;
}
.popover .arrow {
  border-width: @popoverArrowOuterWidth;
}
.popover .arrow:after {
  border-width: @popoverArrowWidth;
  content: "";
}

.popover {
  &.top .arrow {
    left: 50%;
    margin-left: -@popoverArrowOuterWidth;

    border-top-color: #999; // IE8 fallback
    border-top-color: @popoverArrowOuterColor;

    &:after {

      margin-left: -@popoverArrowWidth;
