HTML5 acknowledges that there’s a lot of bad code out there, and it takes the stance that browsers should try to interpret this code for a better user experience. 25. com/ 26. org/wiki/Tag_soup report erratum • discuss 40 • Chapter 1. Creating an Application Layout As nice as that may be, we are going to write well-formed, valid HTML5 for our application. While some would say that we should just know this stuff, the reality is that HTML can be quite complex, and pages—when rendered from many different partials and helpers—can sometimes get broken up.

Delete(:current) options[:class] = (current_tab == title) ? rb def currently_at(tab) render partial: 'layouts/main_nav', locals: {current_tab: tab} end Now adding context-aware main navigation is only a currently_at() away. erb


➤ <%= currently_at 'Creations' %> That single line adds our navigation exactly as it should be, and it’s always that simple, no matter how complex the workflow or how deep the page. Main navigation is just the beginning of the story, as it only provides us with the starting point for each area of the application.

As long as it renders, isn’t it okay? Not necessarily. When we validate our HTML, we are looking to use it as our first line of debugging. If it’s not valid HTML, we really can’t fault the browser for rendering it in an odd way. We fed it something wrong and it did not like the taste. While many browsers have been built to handle this malformed HTML (or “tag soup,” as it’s sometimes called26), in some cases they were not. HTML5 acknowledges that there’s a lot of bad code out there, and it takes the stance that browsers should try to interpret this code for a better user experience.
