We are currently doing on client projects #1 Commenting old style rules and defining new rule for the section we want to change the css rule. #2 Redefining all the style rules in media queries. #3 Using constant values for defining style.

Example of Commenting old style rules and defining new rule. Example: body { /*background-color: #f5f5f5;*/ background-color: #fff; color: #1a212b; } We can simply replace the old style with new one instead of commenting it and then redefining it with new style. Example: body { background-color: #fff; color: #1a212b; }

Example of Redefining all the style rules in media queries. Example:.home-top { background-color: white; padding: 0px 0; margin-top: -150px; } We can simply define the parameter which is changing instead of redefining the same parameters. Example:.home-top { margin-top: -90px; }

We can do following things to change our way of coding projects on the front end #1 We can simply replace the old style rule instead of commenting it out and then defining new style. #2 We can define particular style rules of the desired section in media queries, those we want to change and neglect the other parameters which are same as in the previous media query or the global style. #3 We can use variables instead of constants as suggested by Janis
