8 CSS Properties you must know in 2021 and beyond

If you found value in this thread you will most likely enjoy my tweets too so make sure you follow me on Twitter for more information about web development and how to improve as a developer. This article was first published on my Blog.

1. Display

This property specifies the display behavior of an element.

The most important values: block, inline, inline-block and none.


2. Width and Height

These 2 properties are used to set the height and width of an element.

They can have the following values: auto, length, %, initial or inherit.


3. Margin and Padding

These 2 dictate the spaces between elements on your website.

Margins affect the area outside of borders whereas paddings affect areas inside the border.


4. Border

This one is pretty much self self explanatory, it specifies what kind of border to display.

A few if the values that are allowed: solid, none, hidden, dotted, double.


5. Floats

This property is used for positioning and formatting content on your website.

It can have the following values: left, right, none, inherit.


6. Flexbox

The Flexible Box Layout Module, makes it easier to design flexible responsive layout structure without using float or positioning.

Some properties are: justify-content, align-items, align-content.


7. Color

This property specifies the color of text.

You can use an RBG value, a HEX value or the actual name of the color you want to use.


8. Background

This property specifies the background color of an element.

You can use the same values like for the color property.


The End

I hope found this useful and if you did please let me know. If you have any question feel free to DM me on Twitter .

Nice summary of core CSS. 👍

FYI - MDN is a better resource than W3schools, you should check / learn on there most of the time as the information tends to be more detailed (and more accurate as W3schools still get things wrong today, although they are better than they were in the past).

For example compare the MDN page on background to the W3schools page on background, they are a world apart in terms of completeness, linked information etc.

Sure, MDN is great too
