Hi, I designed an image  banner and was having issues with responsiveness for mobile display until I used width as 100% and not pixels.

The width works fine. But I have been trying to adjust the height to fit perfectly for desktop 💻 and mobile 📱

Is there any standard banner size maybe in pixels that works well for all devices?

@Mrbee
set width as percentage is ok, but you may need to do it also for image as well (you might set 100% width to box, but not to image inside).

I really want to know if there is a standard size for image for example 700x132 px or can Is there a way I can make two banners? one for mobile and another for desktop. Cos if I design an image that fits for mobile it doesn't fit for desktop and vice versa I.e there is always a lot of space between the ad banner and the next item below it.

I placed the code in Inc.category is there a way I make make the ad banner centralize on the website?

@Mrbee
Just use gimp or chrome dev tools to measure size you need.

Alright, I will try it out
