I need to import into my project some CSS files with Webpack 5 and I need to inline all these resources (it's a requirement sadly). Inside the CSS there are some fonts and images with relative URI, like this:
#font-face { font-family: "MyFont"; src: url(./fonts/Roboto-Regular.ttf) format("truetype"); font-weight: normal;}
#font-face { font-family: "MyFont"; src: url(./fonts/Roboto-Bold.ttf) format("truetype"); font-weight: bold;}
#font-face { font-family: "MyFont"; src: url(./fonts/Roboto-Italic.ttf) format("truetype"); font-weight: normal; font-style: italic;}
#font-face { font-family: "MyFont"; src: url(./fonts/Roboto-BoldItalic.ttf) format("truetype"); font-weight: bold; font-style: italic;}
#font-face { font-family: 'Material Icons'; font-style: normal; font-weight: 400; src: url(./fonts/material-icons.woff2) format('woff2'); }
#font-face { font-family: 'Material Icons Outlined'; font-style: normal; font-weight: 400; src: url(./fonts/material-icons-outlined.woff2) format('woff2'); }
* { font-family: "MyFont", "Roboto-Light", "Noto Sans CJK SC", "DejaVu Sans"; }
.UICheckbox { width:80px; height:89px; background-image:url("img/checkboxOFF.png"); background-repeat:no-repeat; }
.UICheckbox.checked { background-image:url("img/checkboxON.png"); }
Since I need to import as base64 the CSS files I cannot actually process automatically the resources found inside of them (contrary to how it is done with PostCSS or similiars).
My current webpack configuration is the following but it just ignores the url() statements:
{
test: /\.(png|jpg|gif)$/i,
type: "asset/inline",
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/i,
type: "asset/inline",
},
{
test: /\.css$/i,
type: "asset/inline",
},
Is there a better way to handle this?
I found a solution that is not really generic or solid but does the job, at least in my case scenario.
The imports are relatives to a fixed source path so the idea is to read the resources found inside the url() rules and process it as DataURI in base64 encoding.
I found quite useful the use of datauri which provides a way to include data in-line as if they were external resources and manages the mimetypes automatically.
npm install datauri --save
Then I had to modify the generator handler inside webpack.config.js to process the resources manually exploiting the datauri package.
const path = require("path");
const Datauri = require("datauri/sync");
const EXTERNAL_ROOT_PATH = "./src/external/dev/";
module.exports = {
...
module: {
rules: [
{
test: /\.css$/i,
type: "asset/inline",
generator: {
dataUrl: (content) => {
content = content.toString();
// Get the resource paths inside the CSS url() rules
let asset_urls = [];
let match,
regex = /url\((.*?)\)/gi;
while ((match = regex.exec(content))) {
asset_urls.push(match[1]);
}
// console.log(asset_urls);
// Convert the resource to a DataURI and replace it inside url()
asset_urls.forEach((file_path) => {
// Sanitize the file path first
sanitized_file_path = file_path.replace(/[\"\']/g, "").replace(/^(?:\.\.\/)+/, "");
const data_uri = Datauri(path.join(EXTERNAL_ROOT_PATH, sanitized_file_path));
// console.log(data_uri.content); //=> "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..."
// console.log(data_uri.mimetype); //=> "image/png"
// console.log(data_uri.base64); //=> "iVBORw0KGgoAAAANSUhEUgAA..."
// console.log(data_uri.buffer); //=> file buffer
content = content.replace(file_path, data_uri.content);
});
return "data:text/css;base64," + Buffer.from(content).toString("base64");
},
},
},
],
},
};
Suppose I have the following #font-face rule(s) and I want to put them as a CSSObject instead of a flat string.
#font-face {
font-family: 'Blah';
font-weight: 400;
font-style: normal;
src:
url('./Blah-Normal.woff2') format('woff2'),
url('./Blah-Normal.woff') format('woff');
}
#font-face {
font-family: 'Blah';
font-weight: 700;
font-style: bold;
src:
url('./Blah-Bold.woff2') format('woff2'),
url('./Blah-Bold.woff') format('woff');
}
...
How can I define it as a CSSObject? I'm trying to pass it over to Mui's MuiCssBaseline and it takes a CSSObject or string. I'd like to pass a CSSObject so that I could add more CSS styling on it more easily and easier to read. But right now it is just a flat string containing only the #font-face definitions.
// import { CSSObject } from '#mui/material';
// import { CSSObject } from '#emotion/styled';
import { CSSObject } from 'styled-components';
const BlahCSSObject = {
'#font-face': {
// magic?
src: [
// it definitely don't like the following format
url('./Blah-Bold.woff2') format('woff2'),
url('./Blah-Bold.woff') format('woff')
]
},
'#font-face': { // would cause dupe keys no?
...
},
...
} as CSSObject;
Thanks!
I think you can use css method from styled-components.
import { css } from 'styled-components'
const myOwnStyle = css`
#font-face {
// styles
}

I have a simple Next.js app that I am developing on macOS (chrome) and have only noticed something is wrong when testing on Windows (chrome, and others too).
I use the font Inter from Google Fonts, nextjs + tailwind takes care of injecting needed css in <head>:
<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossOrigin="" />
<link href="https://fonts.googleapis.com/css2?family=Inter&display=swap" rel="stylesheet" />
which after build translates to:
<style data-href="https://fonts.googleapis.com/css2?family=Inter&display=swap">

</style>
and tailwind config:
theme: {
extend: {
fontFamily: {
sans: ['Inter var', ...defaultTheme.fontFamily.sans],
},
},
},
which then after build, in browsers sets following declaration to <html> tag:
font-family:
Inter var,ui-sans-serif,system-ui,-apple-system,BlinkMacSystemFont,Segoe UI,Roboto,Helvetica Neue,Arial,Noto Sans,sans-serif,Apple Color Emoji,Segoe UI Emoji,Segoe UI Symbol,Noto Color Emoji
The "Inter var" works perfectly on macOS browsers, doesn't work on Windows - it falls back to next option. When I change it to "Inter" only, it works on Windows too, but obviously, the variable font stuff is gone and everything is too thin. Rather than changing all CSS to reflect to this, why does the variable font not work on Windows? I already spend about a whole day on this and other SO posts didn't seem to work for me. Am I doing something wrong?
Update: google font API might return static font files
Due to user-agent detection, you might get static rules in some browsers – even though they support variable fonts flawlessly (e.g. chromium/blink based Opera browser). Firefox or Chrome should work perfectly.
Use the '..' range delimiter and open the css URL in firefox
https://fonts.googleapis.com/css2?family=Inter:wght#100..900
The desired variable #font-face rules should look like this:
#font-face {
font-family: 'Inter';
font-style: normal;
font-weight: 100 900;
src: url(https://fonts.gstatic.com/s/inter/v12/UcC73FwrK3iLTeHuS_fvQtMwCp50KnMa1ZL7.woff2) format('woff2');
}
Note the font-weight: 100 900 property using two values to specify a weight range – Bingo! we got the correct variable font css.
Example1: retrieve #font-face via API css URL
let fontWeight = document.querySelector('#fontWeight');
let fontVariation = document.querySelector('#fontVariation');
let fontSamples = document.querySelectorAll('.fontSample');
fontWeight.addEventListener('change', function(e){
let value = e.target.value;
fontSamples.forEach(function(item, i){
fontSamples[i].setAttribute('style', 'font-weight:'+value);
} )
} );
fontVariation.addEventListener('change', function(e){
let value = e.target.value;
fontSamples.forEach(function(item, i){
fontSamples[i].setAttribute('style', 'font-variation-settings: \'wght\' '+value);
} )
} )
body{
font-family: georgia
}
#font-face {
src: url('https://mdn.github.io/css-examples/variable-fonts/fonts/AmstelvarAlpha-VF.woff2') format('woff2-variations');
font-family:'Amstelvar';
font-style: normal;
}
.amstelvar{
font-family: 'Amstelvar', serif;
}
.inter{
font-family: 'Inter', 'Open Sans', sans-serif;
}
h1{
font-weight: 500;
transition: 0.3s;
}
<link href="https://fonts.googleapis.com/css2?family=Inter:wght#100..900&display=swap" rel="stylesheet">
<h1 class="fontSample inter">Hamburglefonstiv (Inter)</h1>
<h1 class="fontSample amstelvar">Hamburglefonstiv (Amstelvar)</h1>
<p>
<label>Font weight</label>
<input id="fontWeight" type="range" min="100" max="900" step="1">
</p>
<p>
<label>font-variation-settings</label>
<input id="fontVariation" type="range" min="100" max="900" step="1">
</p>
As mentioned before, this won't work in Opera (and maybe other browsers). So the above css URL
https://fonts.googleapis.com/css2?family=Inter:wght#100..900
will return the same result as:
https://fonts.googleapis.com/css2?family=Inter:wght#100;200;300;400;500;600;700;800;900
containing rules for each font-weight.
Example 2: workaround for Opera #font-face
We can copy the correct variable font-face rule to our css.
let fontWeight = document.querySelector('#fontWeight');
let fontVariation = document.querySelector('#fontVariation');
let fontSamples = document.querySelectorAll('.fontSample');
fontWeight.addEventListener('change', function(e) {
let value = e.target.value;
fontSamples.forEach(function(item, i) {
fontSamples[i].setAttribute('style', 'font-weight:' + value);
})
});
fontVariation.addEventListener('change', function(e) {
let value = e.target.value;
fontSamples.forEach(function(item, i) {
fontSamples[i].setAttribute('style', 'font-variation-settings: \'wght\' ' + value);
})
})
body {
font-family: georgia
}
#font-face {
font-family: 'Inter';
font-style: normal;
font-weight: 100 900;
src: url(https://fonts.gstatic.com/s/inter/v12/UcC73FwrK3iLTeHuS_fvQtMwCp50KnMa1ZL7.woff2) format('woff2');
}
#font-face {
src: url('https://mdn.github.io/css-examples/variable-fonts/fonts/AmstelvarAlpha-VF.woff2') format('woff2-variations');
font-family: 'Amstelvar';
font-style: normal;
}
.amstelvar {
font-family: 'Amstelvar', serif;
}
.inter {
font-family: 'Inter', 'Open Sans', sans-serif;
}
h1 {
font-weight: 500;
transition: 0.3s;
}
<h1 class="fontSample inter">Hamburglefonstiv (Inter)</h1>
<h1 class="fontSample amstelvar">Hamburglefonstiv (Amstelvar)</h1>
<p>
<label>Font weight</label>
<input id="fontWeight" type="range" min="100" max="900" step="1">
</p>
<p>
<label>font-variation-settings</label>
<input id="fontVariation" type="range" min="100" max="900" step="1">
</p>
Since the font-family name is defined just as "Inter" (without "var") in the retrieved #font-face declaration you should also refer to it using this name:
theme: {
extend: {
fontFamily: {
sans: ['Inter', ...defaultTheme.fontFamily.sans],
},
},
},
google font UI
Theres is currently no intuitive way to retrieve the correct parameters since the the UI is more focused on static file output.
Selecting multiple styles in the UI will create a static css URL like:
<link href="https://fonts.googleapis.com/css2?family=Inter:wght#100;200;300;400;500;600;700;800;900&display=swap" rel="stylesheet">
Seemless weight interpolation won't work with these files.
To retrieve all supported design axis (e.g Inter supports weight and slant) you can use the "type tester" tab.
Still not perfect. So you're better off concatenating the URL query parameters manually:
https://fonts.googleapis.com/css2?family= +
Inter +
: + slnt + , + wght (design axis names)+
# + -10..0 + , + 100..900 (design axis range values)
Example 3: Inter slant+weight
let fontWeight = document.querySelector('#fontWeight');
let fontVariation = document.querySelector('#fontVariation');
let fontSamples = document.querySelectorAll('.fontSample');
fontWeight.addEventListener('change', function(e) {
let value = e.target.value;
fontSamples.forEach(function(item, i) {
fontSamples[i].setAttribute('style', 'font-weight:' + value);
})
});
fontVariation.addEventListener('change', function(e) {
let value = e.target.value;
fontSamples.forEach(function(item, i) {
fontSamples[i].setAttribute('style', 'font-variation-settings: \'slnt\' ' + value);
})
})
/* latin */
#font-face {
font-family: "Inter";
font-style: oblique 0deg 10deg;
font-weight: 100 900;
src: url(https://fonts.gstatic.com/s/inter/v12/UcCo3FwrK3iLTcviYwY.woff2) format("woff2");
}
body {
font-family: Inter;
}
.inter {
font-family: "Inter", "Open Sans", sans-serif;
}
h1 {
font-weight: 500;
transition: 0.3s;
}
<h1 class="fontSample inter">Hamburglefonstiv (Inter)</h1>
<p>
<label>Font weight</label>
<input id="fontWeight" type="range" min="100" max="900" step="1">
</p>
<p>
<label>font-slant</label>
<input id="fontVariation" type="range" min="-10" max="0" step="1" value="0">
</p>
Worth noting:
You can also style your text via font-variation-settings property.
To change the boldness we would use:
.black{
font-variation-settings: wght 900
}

You can download the ttf file of the font and just include the file in css.
#font-face{
font-family: rocksalt;
src: url('../font/RockSalt-Regular.ttf');
}
here RockSalt is a downloaded font from google fonts and imported to folder named font and use keyword "rocksalt" to add it.
Using the icomoon internet service to create custom icon-fonts, having trouble to make them visible on Leaflet map. Somehow I can not fetch the icons, what have I missed!? I have the data on the map as I can open up the popup, the problem is there is no icons visible....
I have the fonts folder in the correct place and stylesheet is loaded
This is part of the CSS from icomoon I have in a custom-style.css
#font-face {
font-family: 'icomoon';
src: url('myplace/customer/fonts/icomoon.eot?bf4cat');
src: url('myplace/customer/fonts/icomoon.eot?bf4cat#iefix') format('embedded-opentype'),
url('myplace/customer/fonts/icomoon.ttf?bf4cat') format('truetype'),
url('myplace/customer/fonts/icomoon.woff?bf4cat') format('woff'),
url('myplace/customer/fonts/icomoon.svg?bf4cat#icomoon') format('svg');
font-weight: normal;
font-style: normal;
font-display: block;
}
[class^="icon-"], [class*=" icon-"] {
/* use !important to prevent issues with browser extensions that change fonts */
font-family: 'icomoon' !important;
speak: never;
font-style: normal;
font-weight: normal;
font-variant: normal;

.icon-bb .path1:before {
content: "\e900";
color: rgb(35, 31, 32);
}
.icon-bb .path2:before {
content: "\e901";
margin-left: -1em;
color: rgb(0, 0, 0);
}
.icon-bb .path3:before {
content: "\e902";
margin-left: -1em;
color: rgb(0, 0, 0);
} etc....
Then I created a function to look for customer name and give them a className
function getCustomer(x){
x === 'customerBB' ? 'icon- icon-bb' :
x === 'customerCA' ? 'icon- icon-ca' :
x === 'customerCE' ? 'icon- icon-ce' :
'leaflet-div-icon'; //default blue icon if no match
Then a function to return className depending on the results found in feature.properties.customer_name
var setDivIcon = function(feature){
return {
className: getCustomer(feature.properties.customer_name)
};
}
var customerIcon = L.divIcon(setDivIcon);
Later on I use the pointToLayer to add the GeoJSON to the map
customerLayer = L.geoJson(json, {
pointToLayer: function(feature, latlng) {
var time = feature.properties.timeMean_numb;
var point
if (time < 0.167){
point = L.marker(latlng, {icon: L.divIcon(setDivIcon(feature)) }).addTo(time_1);
}
else if (time >= 0.167 && time <= 0.334){
point = L.marker(latlng, {icon: L.divIcon(setDivIcon(feature)) }).addTo(time_2);
}
In your fontface rule you are missing some src:? This could explain them not being fetched
I've read a lot of posts and make my font-face code same as in other answers and it's still not working...
#font-face {
font-family: 'KlavikaLT';
src: url('Klavika-Light.otf') format('opentype');
}
#font-face {
font-family: 'KlavikaLTit';
src: url('Klavika-LightItalic.otf') format('opentype');
}
#font-face {
font-family: 'KlavikaBD';
src: url('Klavika-Bold.otf') format('opentype');
}
#font-face {
font-family: 'KlavikaBDit';
src: url('Klavika-BoldItalic.otf') format('opentype');
}
#font-face {
font-family: 'KlavikaRG';
src: url('Klavika-Regular.otf') format('opentype');
}
.footerleft
{
font-family: KlavikaLT;
}
.footerright
{
font-family: KlavikaBDit;
}
This is my example code that I use. Fonts are in the same folder as stylesheet file. Where do I make a mistake?
EDIT 1
It's funny because it's working on my localhost and all paths are correct. Not working on my server, but I made the same as in my code on other my site and it's working there...
Use this syntax:
<style>
#font-face {
font-family: 'KlavikaLT';
src: url('KlavikaLT.eot');
src: url('KlavikaLT.eot?#iefix') format('embedded-opentype'),
url('KlavikaLT.woff') format('woff'),
url('KlavikaLT.ttf') format('truetype'),
url('KlavikaLT.svg#KlavikaLT') format('svg');
font-weight: normal;
font-style: normal;
}
body { font-family: "KlavikaLT", serif; }
</style>
Make sure the file paths are correct.
This is the specification for #font-face:
#font-face {
[font-family: <family-name>;]?
[src: [ <uri> [format(<string>#)]? | <font-face-name> ]#;]?
[unicode-range: <urange>#;]?
[font-variant: <font-variant>;]?
[font-feature-settings: normal|<feature-tag-value>#;]?
[font-stretch: <font-stretch>;]?
[font-weight: <weight>];
[font-style: <style>];
}
'KlavikaLT' is not a standard font like Courier for example. Your browser has no idea what that font is unless you tell it.
You can tell the browser about your font in a couple of ways:
Post the import at the top of your css:
#import url(https://fonts.googleapis.com/css?family=Open+Sans);
Import with HTML, above your CSS:
<link href='https://fonts.googleapis.com/css?family=Open+Sans' rel='stylesheet' type='text/css'>
Or using JavaScript:
<script type="text/javascript">
WebFontConfig = {
google: { families: [ 'Open+Sans::latin' ] }
};
(function() {
var wf = document.createElement('script');
wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +
'://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
wf.type = 'text/javascript';
wf.async = 'true';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(wf, s);
})(); </script>
Examples copied from Google Fonts.
If you're using a custom font hosted on your own server, you can use the above syntax, but replace the urls with your own. Each one should contain the #font-face, which looks like this:
#font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: 400;
src: local('Open Sans'), local('OpenSans'), url(https://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3ZBw1xU1rKptJj_0jans920.woff2) format('woff2');
}
Just added more extensions of font, like .ttf and .woff. Now it's working perfectly, but don't know why .otf doesn't work at all. Cheers!
