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.
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.
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.
Use these variables to customize tooltips:
@tooltip-max-width: 200px;
@tooltip-color: #FFF;
@tooltip-bg: #000;
@tooltip-opacity: .9;
@tooltip-arrow-width: 5px;
@tooltip-arrow-color: #000;

I was having trouble adjusting popover border thickness. To adjust this I added the @popoverBorderThickness to popovers.less, only those lines are changed. I included the whole file for context.
//
// 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;
}
