how to add custom 26rem value in max-height on tailwindcss - tailwind-css

I'm able to get up to 24rem on max-height using tailwindcss, but not 26rem. How would I add this value? I was not able to find information on how to do this in the docs: https://tailwindcss.com/docs/max-height . The only value-related changes I can find are for adding scale. Thank you!

You could add it manually on tailwind.config.js and recompile it
theme: {
extend: {
height: {
100: '24rem',
},
},
},
therefore, you can use class max-h-100 on your class list.

You have two options:
You can add the values directly inside your class names like so: follow the link
<div class="h-[250px] w-[30rem] absolute top-[1rem] ..."></div>
the second approach is by using config file which locates in your project root directory: <<tailwind.config.js>>: follow the link
module.exports = {
theme: {
extend: {
height: {
'128': '32rem',
}
}
}
}

TailwindCSS doesn't purge plugin classes

I was trying to reduce the size of my CSS file using Tailwind's in-house compiler. This is my config file:
module.exports = {
content: ["./pages/*.html", "./components/**/*", "./src/*"],
mode: "jit",
plugins: [
require("tailwindcss"),
require("tw-elements/dist/plugin"),
require('tailwind-scrollbar')({ nocompatible: true }),
function ({ addVariant }) {
addVariant("child", "& > *");
addVariant("child-hover", "& > *:hover");
},
],
},
};
I have checked that the directories specified in content don't contain any hidden classes, however, it seems that Tailwind includes every class from the package tw-elements and doesn't purge them.
Is there any way how I can get a clean CSS file?
Many thanks for your help!
It is possible to reduce the size of your CSS file using Tailwind's in-house compiler. You can add the purge option to your Tailwind configuration file. Additionally, you can use the whitelist option to specify a list of classes that should not be purged. For example:
module.exports = {
content: ["./pages/*.html", "./components/**/*", "./src/*"],
mode: "jit",
purge: {
content: ['./pages/*.html', './components/**/*', './src/*'],
whitelist: ['tw-elements']
}
....
}

Add gradient as a class in Tailwind css

I want to add this style:
background: linear-gradient(10deg, #AF8800 4.03%, #AA9F1F 6.02%, #A7B334 6.01%)
... to tailwind to be able to add it as a class name. I know that in tailwind we can create classes like this:
bg-[red]
Question: How to do the same action as above with the specified gradient?
you can easily use from and to in your class like
<div class="bg-gradient-to-r from-cyan-500 to-blue-500"></div>
from that's snippet you can gradient from color cyan 500, to blue 500
It is complex gradient so you have to use either arbitrary values or extend Tailwind configuration. Add CSS property almost as it is within square brackets - replace spaces with low dash _. Your class should looks like
<div class="bg-[linear-gradient(10deg,#AF8800_4.03%,#AA9F1F_6.02%,#A7B334_6.01%)] p-10"></div>
If you have less than 3 colors included it may be separated between few "stop-color" classes
<div class="p-10 bg-[linear-gradient(10deg,var(--tw-gradient-stops))] from-[#AF8800_4.03%] via-[#AA9F1F_6.02%] to-[#A7B334_6.01%]"></div>
I've also created this package so you can use bg-gradient-10 instead of bg-[linear-gradient(10deg,var(--tw-gradient-stops))]
If you want to avoid arbitrary variants you may extend configuration for background-image or create static utility plugin
const plugin = require('tailwindcss/plugin')
/** #type {import('tailwindcss').Config} */
module.exports = {
theme: {
extend: {
backgroundImage: {
'my-gradient': 'linear-gradient(10deg, #AF8800 4.03%, #AA9F1F 6.02%, #A7B334 6.01%)'
}
},
},
plugins: [
plugin(function({ addUtilities, addComponents, e, config }) {
addUtilities({
'.bg-my-uitility-gradient': {
'background-image': 'linear-gradient(10deg, #AF8800 4.03%, #AA9F1F 6.02%, #A7B334 6.01%)',
},
})
})
],
}
<div class="p-10 bg-my-gradient"></div>
<div class="p-10 bg-my-uitility-gradient"></div>

Dynamic colors in tailwind css

Is it possible to make the color dynamic in tailwind config.
I want to received the desired color for (primary , accent) from backend via api.
So the user can change the color from the admin panel.
i want to get this hex value from api
Yes this is possible but instead of only primary, you need to return the complete string like bg-primary(as tailwind only recognises the string) where your primary color should be defined in tailwind.config.js file.
For an example you can refer to my answer for this question.
You can try fetching the CSS variables to change you color palette without changing tailwind.config.js
config file:
module.exports = {
theme: {
extend: {
colors: {
"primary": {
100:"var(--primary-color-100)",
200:"var(--primary-color-200)",
},
"accent": "var(--accent-color)"
},
},
},
};
css file:
:root {
--primary-color-100: #fff;
--primary-color-200: #fff00;
--accent-color: #000;
}

Tailwind CSS: How to use custom percentages in padding?

How can we use custom percentage on padding in Tailwind CSS?
My config:
theme: {
extend: {
spacing: {
'80\%': '80%', // p-80% - doesn't work
}
},
},
We can achieve that in the old way with the plain CSS:
.p-80\% {
padding: 80%;
}
But ideally, we can do it with Tailwind too.
Any ideas?
While the other answers do provide an answer, this can be frustrating if you only need to use the custom value once. I found this answer when trying to solve such an issue, so for those who find this after me, tailwind now supports arbitrary values.
You can use them by appending square brackets containing a CSS value (e.g. [80%]) to a prefix such as p- for padding or mr- for margin-right.
<div class="p-[80%]">
Hello world!
</div>
You don't need to escape the percent sign for Tailwind, it will take care of that. Here's a play example https://play.tailwindcss.com/CYR6JOXYyz?file=config
theme: {
extend: {
spacing: {
'80%': '80%', // p-80% - should work
}
},
},
The class Tailwind will create is .p-80\% for the above config.
I found that using spacing to customize more than padding, margin, width, and height all at once
Code
const defaultTheme = require('tailwindcss/defaultTheme')
module.exports = {
theme: {
extend: {
padding: {
'p-80': '80%',
},
// Build your palette here
colors: {
'black': '#393939',
}
}
}
}

Make webpack conditionally load additional or alternative css file

I'm trying to implement a kind of css theming in an angular 4 project. We use webpack 3 for bundling. The product is intended to be used by several companies and has to look according to their brandbooks. So we need themes.
We gonna have several builds, but we don't want to have several versions of code. All themes should remain in the same codebase. The differences are minimal: colors, icons, fonts — everything may be changed in css.
I have thought of several ways to do it, the most obvious would be to implement theming via :host-context for components and change the class of body by changing environment variable for webpack. With such method we will heve every theme inside our bundle, which is not good. Maybe there's another way?
I wonder if it is possible to have webpack load not the css file it is asked for. Instead it could look for another file by pattern, and if it exists, use that file instead of original one. Or load both files.
For example, we have a button.component.ts which imports button.component.css. If we don't tell webpack to use any theme, it works as usual. But if we do, it tries to read button.component.theme-name.css in the same directory. If that file exists, webpack imports it instead (or altogether with) the default file.
That's basically what I'm trying to do. I guess, the same mechanism would be useful for html templates in angular.
Is there a plugin to do such magic? Or maybe some sophisticated loader option? If you have another way to solve my task — feel free to drop a comment!
I created a loader which can append or replace the content of a loaded file with the content of its sibling which has a chosen theme's title in its name.
TL;DR
Create a file with loader.
Use it in webpack config.
Run webpack in THEME=<themeName> evironment.
theme-loader.js
const fs = require('fs');
const loaderUtils = require('loader-utils');
module.exports = function (mainData) {
const options = loaderUtils.getOptions(this);
let themeName = options.theme;
let mode = options.mode;
if (themeName) {
// default mode
if (!Object.keys(transform).includes(mode)) {
mode = 'replace';
}
// fileName.suffix.ext -> fileName.suffix.themeName.ext
const themeAssetPath = this.resourcePath.replace(/\.([^\.]*)$/, `.${themeName}.$1`);
const callback = this.async();
// for HMR to work
this.addDependency(themeAssetPath);
fs.readFile(themeAssetPath, 'utf8', (err, themeData) => {
if (!err) {
callback(null, transform[mode](mainData, themeData));
} else if (err.code === 'ENOENT') {
// don't worry! if it's not here then it's not needed
callback(null, mainData);
} else {
callback(err);
}
});
} else {
return mainData;
}
};
const transform = {
// concat theme file with main file
concat: (mainData, themeData) => mainData + '\n' + themeData,
// replace main file with theme file
replace: (mainData, themeData) => themeData
};
A piece of sample webpack.config.js to use this handmade loader:
resolveLoader: {
modules: [
paths.libs, // ./node_modules
paths.config // this is where our custom loader sits
]
},
module: {
rules: [
// component styles
{
test: /\.css$/,
include: path.join(paths.src, 'app'),
use: [
'raw-loader',
// search for a themed one and append it to main file if found
{
loader: 'theme-loader',
options: {
theme: process.env.THEME,
mode: 'concat'
}
}
]
},
// angular templates — search for a themed one and use it if found
{
test: /\.html$/,
use: ['raw-loader',
{
loader: 'theme-loader',
options: {
theme: process.env.THEME,
mode: 'replace'
}
}
]
}
]
}
For example, an app.component.css:
:host {
background: #f0f0f0;
color: #333333;
padding: 1rem 2rem;
display: flex;
flex-direction: column;
flex: 1;
justify-content: center;
}
nav {
/* ... */
/* something about nav element */
/* ... */
}
header {
/* ... */
/* pile of styles for header */
/* ... */
}
To implement dark theme we don't need to change all that flex and padding staff and maybe nav and header don't have their own background and font color settings. So we'll just have to override host element style. We create app.component.dark.css:
:host {
background: #222222;
color: #e0e0e0;
}
The we run webpack with environment variable THEME set to dark. The loader takes a request to process app.component.css, tries to load app.component.dark.css and voila! Themed css is appended to the end of resulting file. Because of cascade,
if multiple competing selectors have the same importance and specificity, … later rules will win over earlier rules (MDN).
For HTML we don't have such method. So we'll have to rewrite our template completely. Hopefully, you won't need to do it too often. I my case, I wanted to change like header and footer to fit the cutomer's branding demand.
This was my first attempt to create a webpack loader, please leave a comment if you see a problem with it.
