# **What is Tailwind CSS?**
---
[.footer: tailwindcss.com]
# A **utility-first** CSS framework for rapidly building **custom designs**.
^ CSS utility class generator
PostCSS
Make different looking sites using the same class names
No "Tailwind looking site" like there is with Bootstrap
---
[.footer: tailwindcss.com]
# Tailwind CSS is a **highly customizable**, **low-level** CSS framework
^ No components like Bootstrap or Bulma
Configure it per project
Extendable if needed via additional plugins
Avoids the need to name things prematurely
Can extract components if needed (reusability)
---
[.footer: tailwindcss.com/docs/what-is-tailwind/#designed-to-be-customized]
# Tailwind is more than a CSS framework, it's an engine for **creating design systems**.
^ Good default values provided - colours, fonts, padding, widths
Designing with constraints. Using inline styles, every value is a magic number. With utilities, you're choosing styles from a predefined design system, which makes it much easier to build visually consistent UIs.
---
- Text/border/background colours
- Font size/family/weight
- Alignment
- Padding/margin/negative margin
- Flexbox
- Positioning
- Lists
- z-index
- Opacity
- ...
^ All generated from a single, customisable configuration file.

# **How do I use Tailwind?**
^ From the new tailwindcss.com website
---
# With Tailwind, you style elements by **applying pre-existing classes** directly in your HTML.
---
# Using **utility classes** to build custom designs **without writing CSS**
---
## **Benefits**
- You aren't wasting time and energy inventing class names
- Your CSS stops growing
- Making changes feels safer
^ No more adding silly class names like sidebar-inner-wrapper just to be able to style something, and no more agonizing over the perfect abstract name for something that's really just a flex container.
^ Using a traditional approach, your CSS files get bigger every time you add a new feature. With utilities, everything is reusable so you rarely need to write new CSS.
^ CSS is global and you never know what you're breaking when you make a change. Classes in your HTML are local, so you can change them without worrying about something else breaking.
---
---
^ Add padding with p-6
---
^ Rounded image - rounded-full
---
^ Centre image using mx-auto
---
^ Larger text - text-lg
---
^ Purple text - text-purple-500
---
^ Grey text - text-gray-600
---
^ Centre text - text-center
---
^ Responsive: enable flexbox on medium screens - md:flex
---
^ Remove margin around image - md:mx-0
---
^ Re-align text on medium screens - md:text-left
---
^ md:mr-6 - add margin to the side of the image on medium screens
---
^ Increase image size - md:h-24 md:w-24
---
^ Smaller view

- You can't install third-party plugins
---

## `npm install --save-dev` `tailwindcss`
