Mobile First aka consider responsiveness
Think of the challenges mobile designs have and design solutions for them before designing for desktops.
Screen size
Mobile devices can only show so much
Keep it simple. Only what is really important to the user flow is shown
User interaction
You can use your phone differently than your desktop
Click on mouse vs. tap with fingers
No hover option on the mobile.
Data is limited
Large images can cost the user data and slow down the site
Graphics, effects, and images are all developed with mobile challenges in mind
Keep image sizes below 500kb
"save for web" to make sizes smaller
Use appropriate file formats
If it needs a transparency -> PNG
If not then use JPG
Newer format-transparency and condensed- use WebP
Adaptive vs. Responsive Design
Created for specific design's screen
If it's not on the list, then it may not look right on that device

Responsive Design
Displays the same site to every device, but that site is fluid and will change its layout and appearance based on the size and orientation of the device
Ranges that a simple design will adjust to fit
Desktop, tablet, mobile
