2.1.2. tailwind tyypography

2.1.2.1. typeography

2.1.2.1.1. npm install @tailwindcss/typography

2.1.2.1.2. add the plugin

2.1.2.1.3. prose dark:prose-invert

2.1.3. container

2.1.3.1. The container class sets the max-width of an element to match the min-width of the current breakpoint. This is useful if you’d prefer to design for a fixed set of screen sizes instead of trying to accommodate a fully fluid viewport.

2.1.4. inline

2.1.4.1. block vs inline vs inline-block

2.1.4.1.1. display: inline-block, the top and bottom margins/paddings are respected, but with display: inline they are not.

2.1.4.1.2. Compared to display: inline, the major difference is that display: inline-block allows to set a width and height on the element.

2.1.4.2. inline-block

2.1.4.2.1. rather than stack

2.1.5. text

2.1.16.1.1. example

2.1.16.2. block

2.1.16.2.1. I am not sure, though

2.1.17. it puts something on middle of the check box by tailwind

2.1.17.1. checked:after:content-['✓ ']

2.1.18. To override existing css styling

2.1.18.1. !p-0

2.1.18.2. !

2.1.19. put a card on middle of the screen / center of the screen

2.1.19.1. min-h-screen flex items-center justify-center

2.1.19.1.1. use min-h-screen instead of h-screen. If the ui is too long, h-screan will not render it properly

2.1.20. *

2.1.20.1. * / asterisk / wildcard

2.1.20.1.1. In Tailwind CSS, the * symbol is often used in combination with modifiers or selectors to apply styles to all elements or in specific contexts.

2.1.20.2. self-start / self-end / self-center

2.1.20.2.1. self-end

2.1.21. equally divided

2.1.21.1. flex-1

2.1.21.1.1. flex-1: This makes both child div elements consume an equal amount of space within the parent flex container.

2.1.22. Backdropblur

2.1.22.1. <div class="backdrop-blur-sm bg-white/30 ...">

2.1.22.2. backdrop-blur bg-white/50

2.1.22.3. inset-0

2.1.22.3.1. absolute inset-0 for backdrop-blur: inset-0 ensures the backdrop-blur element covers the entire parent container (top: 0; right: 0; bottom: 0; left: 0).

2.1.23. flexbox /flex

2.1.23.1. container

2.1.23.1.1. flex

2.1.23.1.2. justify-center

2.1.23.1.3. justify-start

2.1.23.1.4. justify-evenly

2.1.23.2. items

2.1.23.2.1. items-center

2.1.23.2.2. items-end

2.1.23.2.3. items-strech

2.1.23.3. inline-flex

2.1.23.3.1. inline-flex does not make flex items display inline. It makes the flex container display inline.

2.1.23.3.2. It's like make a div inline or block,

2.1.23.3.3. display: inline-flex is equivalent to display: inline flex

2.1.23.4. space-y-8

2.1.23.4.1. Use this to standardize the distance for items

2.1.23.5. examplpe

2.1.23.5.1. flex flex-col space-y-8

2.1.23.6. flex-wrap

2.1.23.6.1. Use flex-wrap to allow flex items to wrap:

2.1.23.6.2. example

2.1.23.7. flex-none

2.1.23.7.1. size does not change

2.1.23.8. flex-auto

2.1.23.8.1. it grows and shrink

2.1.23.9. flex-col-reverse

2.1.23.9.1. the order of image and the title are reversed

2.1.23.10. flex-row

2.1.23.10.1. flex-col

2.1.24. overflow-hidden

2.1.24.1. image goes out of the card

2.1.24.1.1. image is not rounded at the edges

2.1.24.2. it does not work as expected if the parent component has a flex

2.1.24.3. Does not work with absolutewithout a relative

2.1.24.3.1. good example

2.1.24.3.2. The issue with your overflow-hidden not working lies in the way you're using absolute positioning with margins (ml and mt). The overflow-hidden works on the parent, but because you're positioning the child elements using absolute and margins, they can still appear outside of the parent due to their fixed positioning relative to the closest positioned ancestor (which could be relative or another parent).

2.1.24.3.3. Solution:

2.1.25. layout

2.1.25.1. absolute/relative

2.1.25.1.1. div relative

2.1.26. everytime changing tailwind.config.js you need to rebuild the css

2.1.27. interactivity

2.1.27.1. group-hover:

2.1.27.1.1. element inside another element

2.1.27.2. transition

2.1.27.2.1. ease-out

2.1.27.2.2. duration-500

2.1.27.2.3. types

2.1.27.3. transform

2.1.27.3.1. hover:scale-125

2.1.27.3.2. hover:bg-opacity-50

2.1.27.3.3. focus:

2.1.27.3.4. active:

2.1.27.3.5. rotate-12

2.1.27.3.6. rotate

2.1.27.3.7. translate

2.1.27.3.8. you can not manipulate the order of operation in tailwinds. for doing rotation then translation you should use css instead

2.1.27.4. animation

2.1.27.4.1. animate-bounce

2.1.27.4.2. animate-spin-slow

2.1.27.5. group-hover:animate-ping

2.1.28. z-index

2.1.28.1. example

2.1.28.1.1. <div class="bg-[#38BDF8] h-screen px-[32px] "> <div class="px-[21px] pt-[29px] flex *:w-[80px] z-10 *:h-[36px]"> <div class="bg-[#BAE6FD] rounded-xl border-2 border-[#7DD3FC]"></div> <div class="bg-[#BAE6FD] ] rounded-xl border-2 border-[#7DD3FC] ml-[-7px]"></div> <div class="bg-[#BAE6FD] rounded-xl border-2 border-[#7DD3FC] ml-[-7px]"></div> <div class="bg-white rounded-xl border-2 border-[#7DD3FC] ml-[-7px]"></div> </div> <div class="bg-white h-full rounded-lg mt-[-10px] z-20 relative"></div> </div>

2.1.28.1.2. z-20 relative

2.1.29. clip

2.1.29.1. style="clip-path: polygon(x1 y1, x2 y2,...,xn yn );"

2.1.29.1.1. <div class="w-32 h-32 bg-blue-500" style="clip-path: polygon(0% 0%, 0% 100%, 100% 100%, 100% 25%, 75% 0%);"></div>

2.1.34.2. only use two borders and rotate to create chevron
