Example 2: transition css

/* 
To create a transition effect, you must specify three things:
  transition: (transition-property) (transition-duration) (transition-delay) (transition-timing-function)
  transition: all 0.5s ease-out

transition-property:
    Specifies the name of the CSS property the transition effect is for, by default it's none
    the property could be: width, height, background-color, color, font-size, opacity etc, by applying "all" keyword, it applies on all properties
    transition-property: background-color; --> aply on background only
    transition-property: all; --> apply on all

transition-duration:
    Specifies how many seconds or milliseconds a transition effect takes to complete
    
transition-delay:
    Specifies a delay (in seconds) for the transition effect

transition-timing-function property
    ease - specifies a transition effect with a slow start, then fast, then end slowly (this is default)
    ease-in - specifies a transition effect with a slow start
    ease-out - specifies a transition effect with a slow end
    ease-in-out - specifies a transition effect with a slow start and end

    /* transition: 0.3s;
