Demystifying CSS by Kevin Powell

 

Don't use hieght in px instead go for responsiveness


Flexbox :

Flexbox children goes for smallest possible value..even if you imcrease its sibling content it won't break

and will go try fitting to the limit it is possible to get small



This is the default bheaviour but we can change if we dont want it





even if we add 100% or 1000px it will stull not break but will try to cover the maximum space possible and in the above case it is 50% width as it need to  give equal width to both

Flexbox elements try to get miniumsize when possible and also if the box is limited they will shrink down to a djust and same when width is increased.

If we increase the height of one element all will try to get the same height but if we reduce one element height then others remain same but that one will only get smaller

Since it is quite a confusion thing I will be compiling stuffs based on the materials I have learnt from the internet so as to help myself in the future. 'this' keyword can be considered quite the literal this word is English alphabet atleast for the initial understanding. Let's consider a main table of a house. It will be termed in js langauge as this.table = "main table" If we console log window.table or this.table than we will be considering the main house's table console.log(window.table) //main table Now let consider the dinning table of the house.
