Primer Tooltips
Add tooltips built entirely in CSS to nearly any element. Just add a few classes and an aria-label attribute.
This repository is a module of the full primer repository.
Install
This repository is distributed with npm. After installing
npm, you can install primer-tooltips
with this
command.
$ npm install --save primer-tooltips
Usage
The source files included are written in Sass (scss
) You can simply
point your sass include-path
at your
node_modules
directory and import it like this.
@import "primer-tooltips/index.scss";
You can also import specific portions of the module by importing
those partials from the /lib/
folder. Make sure you
import any requirements along with the modules.
Build
For a compiled css version of this module, a npm
script is included that will output a css version to
build/build.css
The built css file is also included in the
npm package.
$ npm run build

Implementation and accessibility
Attention: we use aria-label
for
tooltips instead of something like data-tooltip
because it
is crucial that the tooltip content is available for screen reader users
as well. However, aria-label
replaces the
text content of an element for screen reader users, so only use tooltip
if there is no better way to present the information, or consider using
title
for supplement 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:
.tooltipped-n
.tooltipped-ne
.tooltipped-e
.tooltipped-se
.tooltipped-s
.tooltipped-sw
.tooltipped-w
.tooltipped-nw
<span class="tooltipped tooltipped-n border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the North side.">
Tooltip North</span>
<span class="tooltipped tooltipped-ne border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the North East side.">
Tooltip North East</span>
<span class="tooltipped tooltipped-e border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the East side.">
Tooltip East</span>
<span class="tooltipped tooltipped-se border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the South East side.">
Tooltip South East</span>
<span class="tooltipped tooltipped-s border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the South side.">
Tooltip South</span>
<span class="tooltipped tooltipped-sw border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the South West side.">
Tooltip South West</span>
<span class="tooltipped tooltipped-w border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the West side.">
Tooltip West</span>
<span class="tooltipped tooltipped-nw border p-2 mb-2 mr-2 float-left" aria-label="This is the tooltip on the North West side.">
Tooltip North West</span>
Tooltip alignment
Align tooltips to the left or right of an element, combined with a directional class to specify north or south.
<span class="tooltipped tooltipped-ne tooltipped-align-left-1 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped NE and aligned left.">
Tooltip North East align left 1</span>
<span class="tooltipped tooltipped-ne tooltipped-align-left-2 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped NE and aligned left.">
Tooltip North East align left 2</span>
<span class="tooltipped tooltipped-se tooltipped-align-left-1 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped SW and aigned left.">
Tooltip South East align left 1</span>
<span class="tooltipped tooltipped-se tooltipped-align-left-2 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped SW and aigned left.">
Tooltip South East align left 2</span>
<span class="tooltipped tooltipped-nw tooltipped-align-right-1 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped NW and aligned right.">
Tooltip North West align right 1</span>
<span class="tooltipped tooltipped-nw tooltipped-align-right-2 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped NW and aligned right.">
Tooltip North West align right 2</span>
<span class="tooltipped tooltipped-sw tooltipped-align-right-1 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped SE and aligned right.">
Tooltip South West align right 1</span>
<span class="tooltipped tooltipped-sw tooltipped-align-right-2 border p-2 mb-2 mr-2 float-left" aria-label="Tooltipped SE and aligned right.">
Tooltip South West align right 2</span>
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
.
<span class="tooltipped tooltipped-multiline tooltipped-n border p-2" aria-label="This is the tooltip with multiple lines. This is the tooltip with multiple lines.">
Tooltip with multiple lines</span>
Tooltips 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
modifier class you can use to override this.
.tooltipped-no-delay
<span class="tooltipped tooltipped-n tooltipped-no-delay border p-2" aria-label="This is the tooltip on the no delay side.">
Tooltip no delay</span>
