Localhost project, phone check up setup

Working on a web project, I want to see if the settings I set are compatible for mobile devices (resolution and so on).
People on stackoverflow recommended to create a hotspot but my phone would die since it sucks.
Anyway I'm running Xampp on ports 80 & 443
I tried using router login page + port 80 - nothing.
10.0.2.2:80 / :8080 / : 443 - nothing.
External IP address of router - 169.254.123.140:80 / :8080 / : 443 - still nothing.

It says page unavailable..
Any way to make localhost on android phone work?

PS:
Localhost or 127.0.0.1 don't work as well (on phone).

Did you checked if your port was work well?
use this to check <.< http://www.canyouseeme.org
-Restart apache.
-Turn off the fire wall.
-Check what's the programs that running and try to turn off some.
-Open TCP Port 80 in Windows Firewall, and try to make connection.

Assuming you have xampp installed on a PC you will not be able to access it from your phone using localhost 127.0.0.1 since the server is not hosted on your phone. I used xampp a long time ago so i dont remember much. But on the computer you have xampp installed on, go to the xampp control panel and look around the settings, you can set ports and other useful settings there. Does that router have wireless?

-OR-

Just use Google Chrome's developer tools. It has a built-in function to automatically resize the browser window to specific resolutions.

After some struggle finally made it work thanks to Dave.

The issue;
chrome://inspect/#devices wasn't showing any devices.

Solution;
Downloaded Android SDK Manager
Installed Platform Tool package(s)
Opened cmd and ran the command "cd (path of platform-tools of SDK manager goes here) adb.exe"
Ran command adb.exe devices (that makes my android connects with my PC by having USB debugger on).
Portforwarded :8080 @ localhost
Used my external IP of router which is 192.168.0.100
Voala.

Thanks for everyone who tried to help ~
Closed as issue has been solved.

PS:
Web project also looks well on phone :3
