![]() Be careful with Boolean attributes as the spec says,Ī number of attributes are boolean attributes. For example is a shorthand for either format is legitimate. Some attributes appear not to take a value. This tells the browser that this particular paragraph is in the English language: Attributes have names and assigned values in the opening tag. Some attributes are allowed on all tags, others are allowed only on a subset. Tags can also have attributes that give the browser extra information about the tag. But this is only the default, the display can be changed using a separate language called Cascading Style Sheets (CSS) without changing the HTML in any way. Here, we have two paragraph elements: I'm a paragraph!īy default, a web browser will display these with a blank line between the paragraphs. The opening tag, the content between the opening and closing tags, and the closing tag is an HTML element. Most -but not all- tags have a corresponding closing tag.Īs with the opening tag, the closing tag is enclosed in angle brackets, but here the tag name is preceded by a backslash, which tells the browser that this is a closing tag: Īs you can see, the tag name is surrounded by angle brackets. But conventionally we use lower cases because capitals look like shouting. Here’s an HTML tag that tells the browser “this is a paragraph”: īrowsers don’t care much about upper or lower case in HTML:, , and even are all the same. (If you already know this, feel free to skip this section.) The Structure of an HTML Elementīefore we begin looking at what constitutes good HTML, let’s take a look at the structure of an HTML element. You’ll get much nicer food that’s far more nutritious if each of the dishes has been cooked by professional chefs using the best ingredients than if each is a frozen ready meal, microwaved by a bored kitchen-hand trainee who doesn’t care at all. And developers using WordPress or React need knowledge of HTML in order to evaluate the quality of the templates or components they are planning to use.Īn analogy is deciding not to cook and going out to a buffet restaurant. Other developers use frameworks like React which glue together pre-written components.īut someone still has to write the templates and components. And this is largely true – 35.8% of the web is powered by WordPress, which assembles pages from templates upon which various themes can be applied. I’m occasionally told that no-one really needs to learn HTML anymore, because nobody writes HTML by hand these days. No-One Writes HTML by Hand Anymore, Grandad! To demonstrate HTML’s future-proof nature, let’s look at the first-ever web page in a modern browser-in this case, Firefox 77 (Developer Edition):Īs you can see, it renders perfectly-and is completely responsive when narrowing the window: And, for the vast majority of sites, the content is what users come for.įor example, here is the Web Accessibility Checklist review on this very site rendered in the 1991 browser:Īrticle on Web Accessibility on this site in the 1991 WorldWideWeb browser It won’t have any styles (CSS 1 wasn’t specified until 1996, and it was 2000 until IE5 for Mac shipped with an almost full implementation) and some of the more exotic punctuation marks or characters might be replaced by their character codes, but you can still read the content. Open a web page by choosing Document > Open from Full Document Reference, and type a URL in the box.Ī well-structured HTML document will still render. To demonstrate the future-proof nature of HTML, you can open the first-ever web browser, which was written by Sir Uncle Timbo himself in 1991.
