$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})

I'm having trouble styling specific bootstrap tooltips. I have learned that I can universally style all the tooltips using these:

.tooltip-inner {
// Styles
}
.comment-tooltip .tooltip.bs-tooltip-auto[x-placement^=top] .arrow::before, .tooltip.bs-tooltip-top .arrow::before {
// Styles
}

Etc. for all the tooltip arrows. But how can I style a specific tooltip (i.e. one element's tooltip). For example let's say this is my HTML:

<span class="red-tooltip" data-toggle="tooltip" data-placement="top" title="Hello world">
Tooltip
</span>

I tried all the CSS combinators (shown below) but none of them seem to let me style ONLY tooltips with the class red-tooltip

.red-tooltip.tooltip-inner {
background-color:#ff0000;
}
.red-tooltip ~ .tooltip-inner {
background-color:#ff0000;
}
.red-tooltip > .tooltip-inner {
background-color:#ff0000;
}
.red-tooltip + .tooltip-inner {
background-color:#ff0000;
}

Any insight would be much appreciated!

If you want only to apply a specific style to only one tooltip when hover it, I hope this will help you.
