I've seen theming discussion related to portlets, availability, etc. However, I couldn't find anything that talked about auto resizing of images.
I am not a themer. It doesn't appear to me that the Plone default theme is truly responsive, as I understand it. I'm trying to understand Plone theme and how it handles responsive behavior related to images. the plone.org page tells us the Plone default theme is responsive.
My understanding of responsive, when related to images, is that images auto resize based on the size of your device. (https://www.w3schools.com/html/html_responsive.aspa)
As a test, I put the identical image in for the logo and in the hero section
(here: http://mckennariley.info/). However, the images display different sizes; and, the top one does not resize as I thought it would because the horizontal bar dispalys on the desktop browser. finally, when viewed on a phone, it again does not resize.
I looked here: https://www.w3schools.com/html/html_responsive.asp to try to understand a little of what makes a theme responsive and found "viewport" . I looked in the Plone theme and found the "viewport" is included.
Is there anything I have to do to change my image to make it responsive?
Am I understanding correctly what is meant by responsive?
Thanks for any ideas or help me see what I'm missing
