Guidance and suggestions for using Solaris icon libraries with Boosted.

While Boosted doesn’t include an icon set by default, Orange does have its own comprehensive icon library called Solaris. While most icon sets include multiple file formats, we prefer SVG implementations for their improved accessibility and vector support.


Solaris is a growing library of SVG icons that are designed by Orange’s Global Design Language Team.

They are not open-source though and should only be used for Orange branded projects. Please refer to our NOTICE.txt file for legal informations.

Use Solaris icons

Solaris provides both PNGs and SVGs, but we strongly recommend to use SVGs. There are quite a few ways to include SVG icons into your HTML—depending on how your project is setup.


Embed your icons within the HTML of your page (as opposed to an external image file). We recommend you use em unit for dimensions to ease resizing via font-size.

<svg xmlns="" width="2em" height="2em" viewBox="0 0 9 14" role="img" aria-label="Left arrow"><path d="M9 2L7 0 0 7l7 7 2-2-5-5 5-5z"/></svg>


You may use an external SVG sprite—a single SVG file containing all your icons—and insert an icon through the <use> element.

SVG sprites allow you to reference an external file similar to an <img> element, but with the power of currentColor for easy theming: see in this example how icons inherit their color from the parent’s .text-primary class, whereas the second icon get grayed out by .text-muted.

<svg width="2em" height="2em" fill="currentColor" aria-hidden="true" focusable="false">
  <use xlink:href="/docs/5.0/assets/img/boosted-sprite.svg#success"/>
<svg width="2em" height="2em" class="text-muted" aria-hidden="true">
  <use xlink:href="/docs/5.0/assets/img/boosted-sprite.svg#info"/>
<svg width="2em" height="2em" fill="currentColor" aria-hidden="true" focusable="false">
  <use xlink:href="/docs/5.0/assets/img/boosted-sprite.svg#warning"/>
<svg width="2em" height="2em" fill="currentColor" aria-hidden="true" focusable="false">
  <use xlink:href="/docs/5.0/assets/img/boosted-sprite.svg#danger"/>

External image

Copy the Solaris icons SVGs to your directory of choice and reference them like normal images with the <img> element.

<img src="/docs/5.0/assets/img/boosted-cross.svg" alt="" aria-hidden="true" width="32" height="32">


You can also use the SVG within your CSS (be sure to escape any characters with our internal escape-svg() function).

When no dimensions are specified via width and height on the <svg>, the icon will fill the available space.

The viewBox attribute is required if you wish to resize icons with background-size. Note that the xmlns attribute is required.

.icon-warning::before {
  display: inline-block;
  content: "";
  background-image: url("data:image/svg+xml,%3csvg xmlns='' viewBox='0 0 30 30'%3e%3cpath fill='%23fc0' d='M15 0a15 15 0 100 30 15 15 0 000-30zm.15 5.39h.01c1.12 0 2 .95 1.92 2.06l-.63 10.43c0 .7-.58.97-1.29.97-.72 0-1.28-.27-1.28-.97l-.63-10.46c-.06-1.09.8-2.01 1.9-2.03zm-.3 15.33c.11 0 .21 0 .31.02 2.19.35 2.19 3.5 0 3.84-2.77.44-3.1-3.86-.3-3.86z'/%3e%3c/svg%3e");
  background-repeat: no-repeat;

Working with SVGs

SVGs are awesome to work with, but they do have some known quirks to work around. Given the numerous ways in which SVGs can be used, we haven’t included these attributes and workarounds in our code.

Known issues include:

  • Focus handling is broken in Internet Explorer and Edge Legacy. When embedding your SVGs, add focusable="false" to the <svg> element. Learn more on Stack Overflow.
  • Browsers inconsistently announce SVGs as <img> tags with voice assistance. Include role="img" when possible to avoid any issues. See this article for details.
  • Safari skips aria-label when used non-focusable SVGs. As such, use aria-hidden="true" when embedding the <svg> file and use CSS to visually hide an equivalent label. More details here.
  • External SVG sprites may not function correctly in Internet Explorer. Use the svg4everybody polyfill as needed.
