Installation Guide

To add the Sveltekit Components library to your project, you can do it in two ways:

1. Use the boilerplate from GitHub.
2. Manual installation from scratch.

1. Use the Boilerplate from GitHub

To install the boilerplate template, open your terminal and use the following command, replacing with your desired project name.

1# Clone the project
2git clone https://github.com/mbparvezme/theui-sveltekit-starter.git app-name
3
4# Install node modules
5npm i
6
7# Run the application
8npm run dev

2. Manually Install from Scratch

To manually install the component library, follow these steps:

2.1    Install Svelte/Sveltekit

1# Install Sveltekit
2npm create svelte@latest my-app
3cd my-app
4
5# Add TailwindCSS
6npx svelte-add@latest tailwindcss
7
8# Install node modules
9npm i
10
11# Install theui-svelte
12npm i theui-sveltekit

2.2    Configuration

Open the TailwindCSS configuration file called tailwind.config.cjs and replace all of its existing content with the code provided below.

1// 1. Update config.content
2// 2. Add config.presets
3const config = {
4  content: [
5    "./src/**/*.{html,js,svelte,ts}",
6    "./node_modules/theui-sveltekit/**/*.{html,js,svelte,ts}", // New line
7  ],
8  presets: [require("theui-sveltekit/preset")], // New line
9  darkMode: "class",
10  theme: {
11    extend: {},
12  },
13
14  plugins: [],
15};
16
17module.exports = config;

If you wish to use the default colors or desire an instant design without any color customization, you can utilize the style.postcss file, which contains all the default CSS variables used in this component library. To do this, open __layout.svelte and import the core style file as follows:

1<script>
2  import "theui-sveltekit/style"; // Add this line inside script tag
3  import "../app.postcss";
4</script>

The file contains the following CSS codes. If you prefer not to use the default colors, you can copy the following code into your app.postcss file and customize it according to your needs.

1@layer base {
2  :root {
3    --ui-brand: 80 70 230; /* #5046E6 */
4    --ui-brand-active: 67 56 202; /* #4338CA */
5    --ui-brand-secondary: 253 230 138; /* #FDE68A */
6    --ui-brand-secondary-active: 252 211 77; /* #FCD34D */
7    --ui-text-on-brand: 255 255 255; /* #FFFFFF */
8    --ui-text-on-brand-secondary: 8 8 24; /* #080818 */
9    --ui-text-default: 8 8 24; /* #080818 */
10    --ui-bg-primary: 255 255 255; /* #FFFFFF */
11    --ui-bg-secondary: 243 244 246; /* #F3F4F6 */
12    --ui-bg-tertiary: 229 231 235; /* #E5E7EB */
13
14    --max-width: 1408px;
15  }
16
17  :root.dark {
18    --ui-text-default: 229 231 235; /* #E5E7EB */
19    --ui-bg-primary: 8 8 24; /* #080818 */
20    --ui-bg-secondary: 22 22 38; /* #161626 */
21    --ui-bg-tertiary: 32 32 48; /* #202030 */
22  }
23
24  body {
25    @apply bg-primary text-default;
26  }
27}

And thats all. You are ready to start your awesome project now.

Default CSS Variables

The component library is built on the powerful foundation of TailwindCSS, a tool capable of generating a wide array of CSS styles and a multitude of variables for your design. However, the real question is, do you truly need an extensive array of CSS variables for your design?

Having the ability to define numerous variables is not the issue. The challenge lies in maintaining design consistency. When you have an overwhelming number of options, it becomes all too easy to lose that consistency, leading to a haphazard and disjointed design.

To address this challenge, the "TheUI Sveltekit" component library introduces a set of carefully curated custom variables that seamlessly integrate with those offered by TailwindCSS. You can effortlessly customize your theme using just one line of code by altering the values of these custom variables.

Utility Variables

There --max-width CSS variable exclusively used in the Container component to ensure that the width of the component remains consistent throughout the entire design. There is no dedicated CSS class for this property. Instead, you can apply it using a Tailwind CSS arbitrary value like max-w-[var(--max-width)].

1--max-width

Colors Variables

"TheUI Sveltekit" component library offers the following CSS variables and their default values. Each CSS variable is prefixed with "ui" to prevent conflicts with other variables.

1  /* Brand colors */
2  --ui-brand
3  --ui-brand-active
4  --ui-brand-secondary
5  --ui-brand-secondary-active
6  /* Text colors */
7  --ui-text-on-brand
8  --ui-text-on-brand-secondary
9  --ui-text-default
10  /* Background colors */
11  --ui-bg-primary
12  --ui-bg-secondary
13  --ui-bg-tertiary

Brand colors are universally accessible, ready to be used in various parts of your design. However, it's important to note that text colors are distinct from background colors, and vice versa. This separation ensures that you have the appropriate colors for both text and background elements, allowing for effective and visually pleasing design combinations.

Use of Custom Colors

You have the flexibility to employ custom classes for integrating the custom colors into your design. The Sveltekit Components library incorporates the following classes to make this process seamless:

CLASS	DESCRIPTION
.[...]-brand	Apply the brand color to your component by using the ".bg-brand" class for the background and ".text-brand" for the foreground.
.[...]-brand-active	Use these classes to indicate different states, such as active or hover, for an element. For example, apply the brand color with slight variations using ".bg-brand-active" for the background and ".text-brand-active" for the foreground.
.[...]-brand-secondary	If you wish to use a secondary brand color for your components, you can do so with the ".bg-brand-secondary" class for the background and ".text-brand-secondary" for the foreground. These classes offer additional design flexibility.
.[...]-brand-secondary-active	Similar to ".[...]-brand-active," but designed for the secondary brand color.
.text-on-brand	This class is for the foreground color when using the background color ".bg-brand."
.text-on-brand-secondary	This class serves as the foreground color when using the background color ".bg-brand-secondary."
.text-default	This class represents the default text/foreground color for the component library.
.bg-primary	Use this class for the default/primary background color.
.bg-secondary	Apply this class for the secondary background color.
.bg-tertiary	Utilize this class for the tertiary background color.

Color Customization

The process of customizing colors in the Sveltekit Components library is straightforward and requires just a single line of code. To change the value of a specific CSS variable, follow these steps:

• Identify the CSS variable you wish to customize. For instance, let's say you want to set your brand color to "rgb(255, 0, 0)" and change the default text color to "rgb(0, 0, 0)."
• Open the ./src/app.css or ./src/app.postcss file in your project, which contains your TailwindCSS styles and add the following lines to the file:

1--ui-brand: 255 0 0;
2--ui-text-default: 0 0 0;

Congratulations! With this simple change, all the components using the brand color and the default text color will automatically adapt to the new color values. No further adjustments are necessary.

Writing the color values in the format provided, such as "255 0 0," rather than the conventional RGB code like "rgb(255, 255, 266," is essential because it aligns with TailwindCSS's methodology for applying opacity to colors.

TailwindCSS allows you to easily adjust the opacity of colors using utility classes like "bg-opacity-50" to set a 50% opacity background. These utility classes are designed to work with color values expressed in the format you mentioned, "255 0 0," and not with conventional RGB codes like "rgb(255, 255, 266)."

By adhering to this format, you ensure that you can seamlessly leverage TailwindCSS's opacity utilities to control the transparency of your colors, providing a consistent and flexible approach to design customization.

The z-index

In this library, several components make use of z-index values. This document will provide you with information about the order of the z-index in these components.

Z-index helps in managing the stacking order of elements and overlays, controlling their arrangement along the z-axis. It is not recommended to customize these values in the design, as doing so may disrupt the layout along the z-axis.

COMPONENT/Property	CLASS/Selector	VALUE (Z-INDEX)
Dropdown	.dropdown .backdrop	10
Dropdown	.dropdown-content	11
Sticky positioned	.sticky, [class$=:sticky]	20
Fixed positioned	.fixed, [class$=:fixed]	30
Offcanvas	.offcanvas	40
Modal	.modal	50
Popup	.popup	60
Tooltip	.tooltip	70
Notifications	.notifications	80
