Solution 1:

Solution

transition: all linear .5s

Explanation

You can take a look at the transition property in CSS.

Taking into consideration the solution above, here's a break down of the syntax:

1) transition-property: defines which property you want to animate. It can be a single property, multiple properties or all; 2) transition-timing-function: transition function to be used, it will define how the animation will occurs; 3) transition-delay: defines how long the animation will take to finish;

Example

$(function(){
    $(window).scroll(function(){
        if($(this).scrollTop() > 100){
            $('header').addClass('fixed-header');
        }
        else{
            $('header').removeClass('fixed-header');
        }
    });
});

header{ padding:0px; position: sticky; top:0px; left:0px; background: #FFF; z-index: 1000;}
header.fixed-header{box-shadow: 20px4px10pxrgba(39, 59, 69, 0.2);}

header.logoimg{width:200px; transition: all linear .5s}
header.fixed-header.logoimg{width:100px;}
