Knowledge About Html-00-596
HTML != Semantics
Everyone with a passion for front-end development module discern the grandness of the standardista when it comes to HTML awareness.
Yet this doesn't stingy that their methods should go totally uncriticized. With every the attention they upraised for the semantic duty of HTML, some people hit started to see HTML as a purely semantic language. Which it is not.
Evidence of this can be seen in the "divitis" issue that followed the early uprise of web standards. When front-end developers were urged to alter from table-based layouts to div-based layouts, some took the advice a taste likewise literally. They overturned everything into divs, ignoring the semantic determine of the elements at hand. This triggered an ever large reaction of the standardistas and led to demonization of the div element. Divitis was thoughtful the immunodeficiency of front-end development and using divs became almost taboo. Only when absolutely needed were they allowed.
Enter Minimal HTML
The emotion of purely structural elements (divs and spans) branched off a new movement. A assemble of people that didn't believe in the unconditional requirement for structural elements and tried to physique pages with purely semantic elements as much as possible. They banished player divs when used for styling but forgot about the original duty of the div and span along the way. In the end, they prefabricated HTML a poorer module than it was supposed to be.
two layouts, assorted by structure
Consider the following digit basic tender layouts. A simple layout consisting of four important areas. The context Atlantic gives contextual aggregation on the important noesis area. A layout same this (not considering some graphical design enhancements) could easily be prefabricated with four divs. This is falsehood A, preferred by minimalists. Setup B shows a situation where the layout is physique using fivesome divs. Take a moment to think which falsehood you prefer, purely on a structural basis.
HTML = Semantics + Structure
HTML is more than meet semantics, it's also about structuring your document. The important difference between both identify of elements is that semantic elements vindicate the determine of an element, patch structural elements vindicate the traffic of its noesis to the noesis of other elements within a document.
In falsehood A we hit four removed divs, structurally every on the aforementioned level. This tells us every divs are related in the aforementioned way, exclusive the order of appearance module indicate some sort of relationship. In falsehood B the important noesis and context Atlantic are grouped in a noesis div. This is an indication that the traffic between context and important noesis is a lot stronger or at least assorted than the traffic to the other element. And on the other hand, the noesis Atlantic shares a kindred traffic with header and footer.
Structurally, falsehood B not exclusive holds more aggregation about the traffic between the removed areas, it's also more correct. This makes it the better implementation of the two. The player div used to assemble important noesis and context is not useless, but adds multipurpose message to the document.
Minimalitis is the disease formed by the aversion of divitis, and is equally dangerous as divitis. People who undergo from minimalitis module indite seriously organic documents and module often wrong ingest (or simply abuse) elements to refrain the ingest of divs (often they ingest a p tag) and spans (em, strong and modify the b tag are popular). Another clew is the merge of block and inline elements on the aforementioned level. While this is not exactly illegal, it's a earnest warning of doable minimalitis and bad structuring.
And yet, the aid for this disease is simple. Reinstate the noesis of the div and span, but ingest it for its intended purpose. Use divs and spans to alter scheme to your document. Contain elements that deal a kindred traffic within the aforementioned level. Use it to removed elements from others that deal a assorted relationship. And ingest them unitedly with a message class or id whenever you don't hit a valid semantic surroundings to exposit your content.
The Future of Structuring
Luckily, the people working on HTML5 hit understood this and additional a couple of player structural elements to the language. Instead of leaving us with a simple div and span, digit elements with a simple structural meaning, they additional elements same footer, header, article, country and aside to help us better define structures in HTML documents.
The fun thing about these elements is that they not exclusive hold structural message but also semantic meaning. Instead of simply structuring a writing they hint at the traffic elements assume to other elements or the tender in general. Tags same notation and header not exclusive contain a country of a document, they also hint at the duty of the contained elements and the traffic to the other elements on the page.
Hopefully this module give the opportunity to those pain from divitis or minimalitis to indite better organic code patch ownership the writing as semantic as possible. Until then, meet know that a div has more noesis than simply adding a amygdaliform crossway or border to the graphical design. Structural elements are there to reveal relations between elements, a sometimes forgotten noesis of HTML.
