Going through the exercises, I am a total noob.
I’m at the exercises that have ‘class=img-responsive’ added as a line next to img (adding of image on browserpage).
My question is, nowhere in the document ‘img-responsive’ has been identified.
I know they’re writing something about bootstrap, and when I research, it appears to be some form of additional coding.
Am I correct to assume, if I’d be coding a blank HTML page, that the ‘img-responsive’ would refer to a file outside my HTML file, containing additional code?
And if so, why not code it within the main html?
Just trying to wrap my head around it all…
Seems like it’s similar to a ‘stylesheet’?
