Difference between Mobile first Design and Responsive Design
It is no longer an option to make your site look good across all the devices in this digital world. The most trendy tools to do this are Mobile-First Design and Responsive Design.

1. Starting Point
The Mobile-First Design starts with the smallest screen which is traditionally a smartphone. The background begins with simple designs and gets complex as the screen size becomes bigger. Conversely, Responsive Design begins with the layout of the desktop. The designers develop an elaborated version of the design that is used on the desktop, then it is simplified to fit on tablets and mobile phones.
2.Design Approach
Progressive enhancement is a technique used in mobile-first. It concentrates on fundamental functions of a mobile and provides additional functionalities of a bigger screen. Responsive design, however, applies what is known as graceful degradation, having the designers first establish a complicated desktop layout and then discarding or modifying features to fit smaller screens.
3.Casscade Media Queries
In the mobile-first approach, the developers are working with media queries of the pattern min-width, i.e. the styles are added in response to the enlargement of the screen. The responsive design, however, employs the max-width media queries where styles vary with a shorter screen size.
4. Performance
Mobile-first design is optimized towards smaller, less powerful devices and therefore, can lead to the faster loading and better performance of the page in smartphones. Responsive design may not be as mobile-optimized, and this is particularly the case when it begins with bulky desks-based content and it is compressed in a tighter screen.
5.Content strategy
Under mobile-first you are compelled to put first things first and this means what the users on the go are accorded first priority. This makes the design uncluttered and more specific. The process of the responsive design tends to copy desktop material and adapt it to mobile, which might result in a crammed or less concentrated mobile structure.
6. User Experience

Responsive design can provide the same experience on different kinds of devices, yet it still might not seem completely optimized on mobile, and a few changes are needed.
7.Development Complexity
