How to use the new Material Design Icon themes: Outlined, Rounded, Two-Tone and Sharp?

Update (31/03/2019) : All icon themes work via Google Web Fonts now.

As pointed out by Edric, it's just a matter of adding the google web fonts link in your document's head now, like so:

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp" rel="stylesheet">

And then adding the correct class to output the icon of a particular theme.

<i class="material-icons">donut_small</i>
<i class="material-icons-outlined">donut_small</i>
<i class="material-icons-two-tone">donut_small</i>
<i class="material-icons-round">donut_small</i>
<i class="material-icons-sharp">donut_small</i>

The color of the icons can be changed using CSS as well.

Note: the Two-tone theme icons are a bit glitchy at present.

Update (14/11/2018) : List of 16 outline icons that work with the "_outline" suffix.

Here's the most recent list of 16 outline icons that work with the regular Material-icons Webfont, using the _outline suffix (tested and confirmed).

(As found on the material-design-icons github page. Search for: "_outline_24px.svg")

<i class="material-icons">help_outline</i>
<i class="material-icons">label_outline</i>
<i class="material-icons">mail_outline</i>
<i class="material-icons">info_outline</i>
<i class="material-icons">lock_outline</i>
<i class="material-icons">lightbulb_outline</i>
<i class="material-icons">play_circle_outline</i>
<i class="material-icons">error_outline</i>
<i class="material-icons">add_circle_outline</i>
<i class="material-icons">people_outline</i>
<i class="material-icons">person_outline</i>
<i class="material-icons">pause_circle_outline</i>
<i class="material-icons">chat_bubble_outline</i>
<i class="material-icons">remove_circle_outline</i>
<i class="material-icons">check_box_outline_blank</i>
<i class="material-icons">pie_chart_outlined</i>

Note that pie_chart needs to be "pie_chart_outlined" and not outline.

This is a hack to test out the new icon themes using an inline tag. It's not the official solution.

As of today (July 19, 2018), a little over 2 months since the new icons themes were introduced, there is No Way to include these icons using an inline tag <i class="material-icons"></i>.

+Martin has pointed out that there's an issue raised on Github regarding the same: https://github.com/google/material-design-icons/issues/773

So, until Google comes up with a solution for this, I've started using a hack to include these new icon themes in my development environment before downloading the appropriate icons as SVG or PNG. And I thought I'd share it with you all.

IMPORTANT: Do not use this on a production environment as each of the included CSS files from Google are over 1MB in size.

Google uses these stylesheets to showcase the icons on their demo page:

Outline:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">

Rounded:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/round.css">

Two-Tone:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/twotone.css">

Sharp:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">

Each of these files contain the icons of the respective themes included as background-images (Base64 image-data). And here's how we can use this to test out the compatibility of a particular icon in our design before downloading it for use in the production environment.

STEP 1:

Include the stylesheet of the theme that you want to use. Eg: For the 'Outlined' theme, use the stylesheet for 'outline.css'

STEP 2:

Add the following classes to your own stylesheet:

.material-icons-new {
    display: inline-block;
    width: 24px;
    height: 24px;
    background-repeat: no-repeat;
    background-size: contain;
}

.icon-white {
    webkit-filter: contrast(4) invert(1);
    -moz-filter: contrast(4) invert(1);
    -o-filter: contrast(4) invert(1);
    -ms-filter: contrast(4) invert(1);
    filter: contrast(4) invert(1);
}

STEP 3:

Use the icon by adding the following classes to the <i> tag:

  1. material-icons-new class

  2. Icon name as shown on the material icons demo page, prefixed with the theme name followed by a hyphen.

Prefixes:

Outlined: outline-

Rounded: round-

Two-Tone: twotone-

Sharp: sharp-

Eg (for 'announcement' icon):

outline-announcement, round-announcement, twotone-announcement, sharp-announcement

3) Use an optional 3rd class icon-white for inverting the color from black to white (for dark backgrounds)

Changing icon size:

Since this is a background-image and not a font-icon, use the height and width properties of CSS to modify the size of the icons. The default is set to 24px in the material-icons-new class.

Example:

Case I: For the Outlined Theme of the account_circle icon:

  1. Include the stylesheet:
<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">
  1. Add the icon tag on your page:
<i class="material-icons-new outline-account_circle"></i>

Optional (For dark backgrounds):

<i class="material-icons-new outline-account_circle icon-white"></i>

Case II: For the Sharp Theme of the assessment icon:

  1. Include the stylesheet:
<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">
  1. Add the icon tag on your page:
<i class="material-icons-new sharp-assessment"></i>

(For dark backgrounds):

<i class="material-icons-new sharp-assessment icon-white"></i>

I can't stress enough that this is NOT THE RIGHT WAY to include the icons on your production environment. But if you have to scan through multiple icons on your in-development page, it does make the icon inclusion pretty easy and saves a lot of time.

Downloading the icon as SVG or PNG sure is a better option when it comes to site-speed optimization, but font-icons are a time-saver when it comes to the prototyping phase and checking if a particular icon goes with your design, etc.

I will update this post if and when Google comes up with a solution for this issue that does not involve downloading an icon for usage.


For angular material you should use fontSet input to change the font family:

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />

<mat-icon>edit</mat-icon>
<mat-icon fontSet="material-icons-outlined">edit</mat-icon>
<mat-icon fontSet="material-icons-two-tone">edit</mat-icon>
...

As of 27 February 2019, there are CSS fonts for the new Material Icon themes.

However, you have to create CSS classes to use the fonts.

The font families are as follows:

  • Material Icons Outlined - Outlined icons
  • Material Icons Two Tone - Two-tone icons
  • Material Icons Round - Rounded icons
  • Material Icons Sharp - Sharp icons

See the code sample below for an example:

body {
  font-family: Roboto, sans-serif;
}

.material-icons-outlined,
.material-icons.material-icons--outlined,
.material-icons-two-tone,
.material-icons.material-icons--two-tone,
.material-icons-round,
.material-icons.material-icons--round,
.material-icons-sharp,
.material-icons.material-icons--sharp {
  font-weight: normal;
  font-style: normal;
  font-size: 24px;
  line-height: 1;
  letter-spacing: normal;
  text-transform: none;
  display: inline-block;
  white-space: nowrap;
  word-wrap: normal;
  direction: ltr;
  -webkit-font-feature-settings: 'liga';
  -webkit-font-smoothing: antialiased;
}

.material-icons-outlined,
.material-icons.material-icons--outlined {
  font-family: 'Material Icons Outlined';
}

.material-icons-two-tone,
.material-icons.material-icons--two-tone {
  font-family: 'Material Icons Two Tone';
}

.material-icons-round,
.material-icons.material-icons--round {
  font-family: 'Material Icons Round';
}

.material-icons-sharp,
.material-icons.material-icons--sharp {
  font-family: 'Material Icons Sharp';
}

EDIT: As of 10 March 2019, it appears that there are now classes for the new font icons:

body {
  font-family: Roboto, sans-serif;
}
<!DOCTYPE html>
<html>

<head>
  <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500|Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp">
</head>

<body>
  <section id="original">
    <h2>Baseline</h2>
    <i class="material-icons">home</i>
    <i class="material-icons">assignment</i>
  </section>
  <section id="outlined">
    <h2>Outlined</h2>
    <i class="material-icons-outlined">home</i>
    <i class="material-icons-outlined">assignment</i>
  </section>
  <section id="two-tone">
    <h2>Two tone</h2>
    <i class="material-icons-two-tone">home</i>
    <i class="material-icons-two-tone">assignment</i>
  </section>
  <section id="rounded">
    <h2>Rounded</h2>
    <i class="material-icons-round">home</i>
    <i class="material-icons-round">assignment</i>
  </section>
  <section id="sharp">
    <h2>Sharp</h2>
    <i class="material-icons-sharp">home</i>
    <i class="material-icons-sharp">assignment</i>
  </section>
</body>

</html>

EDIT #2: Here's a workaround to tint two-tone icons by using CSS image filters (code adapted from this comment):

body {
  font-family: Roboto, sans-serif;
}

.material-icons-two-tone {
  filter: invert(0.5) sepia(1) saturate(10) hue-rotate(180deg);
  font-size: 48px;
}

.material-icons,
.material-icons-outlined,
.material-icons-round,
.material-icons-sharp {
  color: #0099ff;
  font-size: 48px;
}

    <i class="material-icons-two-tone">assignment</i>

  <section id="rounded">
    <h2>Rounded</h2>
    <i class="material-icons-round">home</i>
    <i class="material-icons-round">assignment</i>

    <h2>Sharp</h2>
