 However having a rule for each thing can make the code much more difficult to maintain, so you can use the selector:
 
-```css

 ### CSS box-sizing
 
 The script has not been tested on older browsers such as IE7, but is likely to work depending on `ActiveX` support, however `box-sizing` may not work or you may be using a modern browser and you have changed the control of `box-sizing` to something like:
 
 
-```css
+``` css
 .my-element {
     box-sizing: content-box !important;
     padding: 10px !important;
     border: 1px #ccc solid !important;
 }
-```
+``` 
 
 In both cases you can suffer side effects maybe use `padding` or `border`.
