Hello BootStraper,
You have a nice website, but I see some errors on your code.
Do you have a full commented code for the .html and CSS ?
Here are some of my observations :
- Intro is not 100% width
- Intro as some "clipping" due to the load of the blue bubble.
- Buttons are not the same size into mobile / tablet
- Header as a top padding when into moble / tablet
- Some elements are not necessesary when on mobile, why not hidding them ?
Your design is good, with a code color (Blue/Black).
But I will make it more Flat, whith another Police.
Have a nice day !
