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

Google has revamped its Material Design Icons with 4 new preset themes:

Outlined, Rounded, Two-Tone and Sharp, in addition to the regular Filled/Baseline theme:

But, unfortunately, it doesn't say anywhere how to use the new themes.

I've been using it via Google Web Fonts by including the link:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

And then using the required icon as suggested in the documentation:

<i class="material-icons">account_balance</i>

But it always shows the 'Filled/Baseline' version.

I've tried doing the following to use the Outlined theme instead:

<i class="material-icons">account_balance_outlined</i>
<i class="material-icons material-icons-outlined">account_balance</i>

and, changing the Web Fonts link to:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons&style=outlined" rel="stylesheet">

etc. But it doesn't work.

And there's no point in taking shots in the dark like that.

tl;dr: Has anyone tried using the new themes? Does it even work like the baseline version (inline html tag)? Or, is it only meant to be downloaded as SVG or PNG formats?

Thanks in advance.

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">

2) 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">

2) 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.

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">

<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;
}

What worked for me is using _outline not _outlined after the icon name.

<mat-icon>info</mat-icon>

<mat-icon>info_outline</mat-icon>

New themes are probably not (yet?) part of the Material Icons font. Link.

The Aj334's recent edit works perfectly.

google CDN

<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">

Icon Element

<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>

If you already have material-icons working in your web project, just need to update your reference in the html file and the used class for icons:

html reference:

Before

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" />

After

<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" />

material icons class:

After that just check wich className are you using:

Before:

<i className="material-icons">weekend</i>

After:

<i className="material-icons-outlined">weekend</i>

that works for me... Pura vida!

The webfonts link works now, in all browsers!

Simply add your themes to the font link separated by a pipe (|), like this

<link href="https://fonts.googleapis.com/icon?family=Material+Icons|Material+Icons+Outlined" rel="stylesheet">

Then reference the class, like this:

// class="material-icons" or class="material-icons-outlined"

<i class="material-icons">account_balance</i>
<i class="material-icons-outlined">account_balance</i>

This pattern will also work with Angular Material:

<mat-icon>account_balance</mat-icon>
<mat-icon class="material-icons-outlined">account_balance</mat-icon>

I ended up using IcoMoon app to create a custom font using only the new themed icons I required for a recent web app build. It's not perfect but you can mimic the existing Google Font functionality pretty nicely with a little bit of setup. Here's a writeup:

https://medium.com/@leemartin/how-to-use-material-icon-outlined-rounded-two-tone-and-sharp-themes-92276f2415d2

If someone is feeling daring, they could convert the entire theme using IcoMoon. Hell, IcoMoon probably has an internal process that would make it easy since they already have the original Material Icons set in their library.

Anyway, this isn't a perfect solution, but it worked for me.

I was unsatisfied that until know Google hasn't yet released their new designs as font or svg icon set. Therefore I put together a small npm package to solve the problem.

https://www.npmjs.com/package/ts-material-icons-svg

Simply import the icons you wanna use and add them to your registry. This also supports tree shaking since only those icons are added to your project that you really want and/or need.

npm i --save https://github.com/MarcusCalidus/ts-material-icons-svg.git

to use two tone icons for example

import {icon_edit} from 'ts-material-icons-svg/dist/twotone';

matIconRegistry.addSvgIcon(
            'edit',
            domSanitizer.bypassSecurityTrustResourceUrl(icon_edit),
        );

In your html template you now can use the new icon

<mat-icon svgIcon="edit"></mat-icon>

Somewhat hilariously, Google has made a font that works correctly in Safari but not in Chrome. Here's the https://codepen.io/anon/pen/zbavza

<i class="material-icons-round red">warning</i>

In reference to https://stackoverflow.com/a/54902967/4740291 and not being able to change the color using css.
