  1. calc()
  • When specifying CSS property values, you can conduct computations using the calc() CSS function
  •  Anywhere a "length," "frequency," "angle," "time," "percent," "number," or "integer" is permitted, it can be used. 
  • Operations like addition, subtraction, multiplication and division can also be performed inside the calc() function.
  • Example :
    • width: calc(180% - 20px);
    • width: calc(5em * 2);
    • z-index : calc(5/2)
       
       
  • Example :

width: calc(100% - 200px); 

The above example will calculate the width mentioned inside calc() function and generate suitable width after performing calculation. It will calculate 100% width of the element, then subtract 200px from it, giving us the final width.

       
       

 

  • Output :

 

       

 

       

 

  • Code :

 

<!DOCTYPE html>

        body{

else-if condition in if-else statements: Concatenation in JavaScript :

  else-if condition in if-else statements: While specifying conditions for if-else statements, there may arise a need to include more than just two scenarios. For example, suppose we have a variable ‘n’ and we have to check if it is positive or negative. JS code for this problem would look like this: Quite simple, right? However, suppose we twist this problem a bit. If we have to check if the value of ‘n’ is positive, negative, OR zero. Can we do it using only if-else?  No, right? Here comes the scenario where we have to check more than two conditions and give output for each. This is where else-if comes into the game.  Structure of if else-if else looks something like this: If (condition 1)  { statements } else if (condition 2) { statements } else  { statements }   Working for the above code is explained as follows: Condition 1 is checked first. If it is true, statements inside the first block are executed and the remaining conditions are not checked. If t...
