How to ensure compatibility without using framework

[giannis196]

Hi everyone, i made a test webpage and i noticed the page is different between chrome and firefox and so i am here to ask if there is any way to ensure compatibility (both cross browser and cross device) without using any framework.

Is there any "trick" to do that?

So, what do you do to ensure the compatibility to webpages?

Thanks!

(btw i don't think i can post the page here because i have very limited bandwidth since i have the "free account")





I am attaching 2 images, the 1 is from chrome and the other is from firefox


So, why do i have this micro-difference?

Thanks!

I would recommend adding the code that makes what's inside the pictures.
