I'm working on my portfolio which has **three** section tags. I've declared a background colour for the whole body, however, I want different colours to take **full width** for the 2nd & 3rd section tags -- just like body background colour.

While I did try to achieve that using the below code, the background colour for both the section tags isn't taking full page width. Any help on this would be appreciated. 

**HTML**

```
