Customizing twitter bootstrap popover arrow

Question

I could not find any relevant information on this, but I find it hard to swallow that it's not doable.

How can I customise the arrow for the popovers? I already did but changing the classes .arrow and such, but the position of the popover gets screwed up.

So, what is the correct way to do so? I couldn't find any documentation.

Following are the classes I've been using, so far the arrow looks wrong:

.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;
        }

The arrow should be pointing to the red square

Thanks.

Answer 1

For anyone using a custom style.css to simply overwrite bootstrap without recompiling the LESS, the css rule you're looking for is .popover.top > .arrow:after { border-top-color: yourColorHere; } to change the color of just the arrow.

Answer 2

Twitter Bootstrap is based on Less.

If you want to change the appearance of its arrows use the bootstrap less variables to do so.

// 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);

If you are using Sass instead do the same with the Sass Variables.

Sadly the TB-Customizer doesn't have all the variables so you might have to compile it on your own.

Edit:

Good news the new Bootstrap 3 customizer now provides these options.
