Add tooltips built entirely in CSS to nearly any element.
## Implementation and accessibility
Tooltips as a UI pattern should be our last resort for conveying information because it is hidden by default and often with zero or little visual indicator of its existence.
Before adding a tooltip, please consider: Is this information essential and necessary* Can the UI be made clearer? Can the information be shown on the page by default?
**Attention**: we use `aria-label` for tooltip contents, because it is crucial that they are accessible to screen reader users. However, `aria-label` **replaces** the text content of an element in screen readers, so only use `.tooltipped` on elements with no existing text content, or consider using `title` for supplemental information.
**Note:** Tooltip classes will conflict with Octicon styles, and as such, must be applied to the parent element instead of the icon.
## Tooltip direction
Specify the direction of a tooltip with north, south, east, and west directions:
```html live
<div class="d-flex flex-justify-center pt-4">
<span class="tooltipped tooltipped-nw m-2 p-2 border" aria-label="This is the tooltip on the North West side.">
.tooltipped-nw
</span>
<span class="tooltipped tooltipped-n m-2 p-2 border" aria-label="This is the tooltip on the North side.">
.tooltipped-n
</span>
<span class="tooltipped tooltipped-ne m-2 p-2 border" aria-label="This is the tooltip on the North East side.">
.tooltipped-ne
</span>
</div>
<div class="d-flex flex-justify-center">
<span class="tooltipped tooltipped-w m-2 p-2 border" aria-label="This is the tooltip on the West side.">
.tooltipped-w
</span>
<span class="tooltipped tooltipped-e m-2 p-2 border" aria-label="This is the tooltip on the East side.">
.tooltipped-e
</span>
</div>
<div class="d-flex flex-justify-center pb-4">
<span class="tooltipped tooltipped-sw m-2 p-2 border" aria-label="This is the tooltip on the South West side.">
.tooltipped-sw
</span>
<span class="tooltipped tooltipped-s m-2 p-2 border" aria-label="This is the tooltip on the South side.">
.tooltipped-s
</span>
<span class="tooltipped tooltipped-se m-2 p-2 border" aria-label="This is the tooltip on the South East side.">
.tooltipped-se
</span>
</div>
```
## Tooltip alignment
Align tooltips to the left or right of an element, combined with a directional class to specify north or south. Use a modifier of `1` or `2` to choose how much the tooltip's arrow is indented.
```html live
<div class="d-flex flex-justify-center pt-4">
<span class="tooltipped tooltipped-nw tooltipped-align-right-1 m-2 p-2 border" aria-label="Tooltipped NW and aligned right.">
.tooltipped-nw .tooltipped-align-right-1
</span>
<span class="tooltipped tooltipped-ne tooltipped-align-left-1 m-2 p-2 border" aria-label="Tooltipped NE and aligned left.">
.tooltipped-ne .tooltipped-align-left-1
</span>
</div>
<div class="d-flex flex-justify-center">
<span class="tooltipped tooltipped-nw tooltipped-align-right-2 m-2 p-2 border" aria-label="Tooltipped NW and aligned right.">
.tooltipped-nw .tooltipped-align-right-2
</span>
<span class="tooltipped tooltipped-ne tooltipped-align-left-2 m-2 p-2 border" aria-label="Tooltipped NE and aligned left.">
.tooltipped-ne .tooltipped-align-left-2
</span>
</div>
<div class="d-flex flex-justify-center">
<span class="tooltipped tooltipped-sw tooltipped-align-right-1 m-2 p-2 border" aria-label="Tooltipped SE and aligned right.">
.tooltipped-sw .tooltipped-align-right-1
</span>
<span class="tooltipped tooltipped-se tooltipped-align-left-1 m-2 p-2 border" aria-label="Tooltipped SW and aligned left.">
.tooltipped-se .tooltipped-align-left-1
</span>
</div>
<div class="d-flex flex-justify-center pb-4">
<span class="tooltipped tooltipped-sw tooltipped-align-right-2 m-2 p-2 border" aria-label="Tooltipped SE and aligned right.">
.tooltipped-sw .tooltipped-align-right-2
</span>
<span class="tooltipped tooltipped-se tooltipped-align-left-2 m-2 p-2 border" aria-label="Tooltipped SW and aligned left.">
.tooltipped-se .tooltipped-align-left-2
</span>
</div>
```
## Tooltips with multiple lines
Use `.tooltipped-multiline` when you have long content. This style has some limitations: you cannot pre-format the text with newlines, and tooltips are limited to a max-width of `250px`.
```html live
<div class="d-flex flex-justify-center pt-6">
<span class="tooltipped tooltipped-n tooltipped-multiline m-2 p-2 border" aria-label="This is the tooltip with multiple lines. This is the tooltip with multiple lines.">
.tooltipped-multiline
</span>
</div>
```
## Tooltips with no delay
By default the tooltips have a slight delay before appearing. This is to keep multiple tooltips in the UI from being distracting. There is a `.tooltipped-no-delay` modifier class you can use to override this.
```html live
<div class="d-flex flex-justify-center pt-4">
<span class="tooltipped tooltipped-n tooltipped-no-delay m-2 p-2 border" aria-label="This is the tooltip on the no delay side.">
.tooltipped-no-delay
</span>
</div>
```
