WHY ARE WE TALKING HTML?
@MANDY_KERR HTML IS SIMPLE
@MANDY_KERR WE MAKE THE MISTAKE OF ASSUMING BECAUSE IT’S SIMPLE IT’S NOT VALUABLE
@MANDY_KERR IS THERE ANY VALUE IN PEOPLE WHO CANNOT WRITE JAVASCRIPT?
THERE ARELOTS OF OPINIONS ON THE MATTER

@MANDY_KERR COMBINE ELEMENTS FOR IMPROVED CONTEXT
@MANDY_KERR If you have images, illustrations and diagrams use the

HTML, the foundation of the web! With so much time being spent on typed javascript, functional programming, unit tests, visual regression testing, tools, frameworks and a drive to write better more efficient code we often forget that the web starts with HTML.
I will demonstrate why semantics are important and why choosing the right html elements will help you write better code not just for browsers but other technologies as well.
