Semantic html

Not about performance Semantic markup isn't about performance, it's about meaning. Let's imagine two parallel universes. • In Dumb HTML World, there is only one tag: . How would you specify where styles should be applied? How would browsers know how to render the page? How would screen readers for the blind differentiate between headlines and text and footnotes and menu items? You'd have to add all kinds of awkward attributes. • Meanwhile, in Detailed HTML World, there are loads of names. You've got and and and and and and , etc. Now a user agent (a browser or screen reader) can make reasonable assumptions about how to style those, or make them interactive, or read them aloud. For example, a browser will make s look clickable and will enable moving between them with the tab key, whereas if you use a , it won't know to do that. A screen reader might give more priority to reading the s than the s. If you want to override the user agent's default treatment of an element, or if a user agent is set to do so, it's easier to target specific kinds of content. For example: • "My site is about jewelry, so I want list bullets to appear as diamonds." • "My user is blind, so I should announce that there are images, offer to read the associated captions, and not bother downloading the actual image data." • "My user doesn't care about footnotes and wants to ignore them." The real world is somewhere between these two scenarios. Some aspects of semantic HTML are a bit idealistic, but...

Semantic HTML elements are those that clearly describe their meaning in a human- and machine-readable way. Elements such as , and are all considered semantic because they accurately describe the purpose of the element and the type of content that is inside them. What are Semantic Elements? HTML was originally created as a markup language to describe documents on the early internet. As the internet grew and was adopted by more people, its needs changed. Where the internet was originally intended for sharing scientific documents, now people wanted to share other things as well. Very quickly, people started wanting to make the web look nicer. Because the web was not initially built to be designed, programmers used different hacks to get things laid out in different ways. Rather than using the to describe information using a table, programmers would use them to position other elements on a page. As the use of visually designed layouts progressed, programmers started to use a generic “non-semantic” tag like . They would often give these elements a class or id attribute to describe their purpose. For example, instead of this was often written as . As HTML5 is still relatively new, this use of non-semantic elements is still very common on websites today. List of new semantic elements The semantic elements added in HTML5 are: • • • • • • • • • • • • • Elements such as , , , , , and act more or less like elements. They group other elements together into page sect...

November 30, 2020 Introduction HTML has been around since the early 1990s. This may not seem like a long time, but in the world of programming, it’s practically a century! However, since its invention, HTML has changed a lot and so has the web. In recent years, certain thoughts may have crossed your mind, like “what is semantic HTML? and “What are the benefits?”. Well, I am here to tell you that you’re in luck because I am going to explain it to you! What Is Semantic HTML? Semantic HTML is a style of writing HTML that focuses on labelling code usefully and meaningfully to both the developer and the browser. Since the advent of HTML5, semantic code has become both more prevalent and necessary for any frontend developer to understand and utilize. For instance, the and elements tell nothing about their content. While elements such as , and clearly state what it’s content is meant to display within their tags. The prior tags are non-semantic; the later tags are semantic. So what are the benefits of semantic HTML code? Well, there are essentially three broad categories that semantic HTML helps to improve: maintainability, accessibility and SEO. Let’s dive into how these categories can be improved with Semantic HTML. What Are The Benefits of Semantic HTML? Maintainability Maintainability is one of the critical factors in writing good, high-quality code. It’s an aspect of coding that should always be at the forefront of a developer’s mind. Semantic HTML helps promote maintaina...

It's really up to you what the elements involved represent, as long as the hierarchy makes sense. You just need to bear in mind a few best practices as you create such structures: • Preferably, you should use a single per page—this is the top level heading, and all others sit below this in the hierarchy. • Make sure you use the headings in the correct order in the hierarchy. Don't use elements to represent subheadings, followed by elements to represent sub-subheadings—that doesn't make sense and will lead to weird results. • Of the six heading levels available, you should aim to use no more than three per page, unless you feel it is necessary. Documents with many levels (fo...

Semantic HTML. What, Why, and How In my What Semantic HTML helps the developer and the browser in creating great development and accessible experience. According to Why One of its main benefits, and probably the most important, is it helps to make a website accessible. Screen readers, or any assistive device scan the web page for any elements which give meaning such as a to understand that it is a paragraph or to know it is a heading. Accessible sites deliver content to all types of users which is the main objective of any website and web developer. Not only this, but it brings great results such as avoiding a lawsuit ( Do not forget that apart from semantic HTML there are many other aspects of making a website accessible such as alt in images, aria labels, and the use of correct color contrast. Check this Other benefits semantic HTML provides: • Easier development experience. It is easier for the developer to understand that is meant to trigger some event rather than with an event listener. • Better for mobile devices. According to • Good for SEO. Search engines give more importance to keywords inside links, headings, or footers than those included in simple divs or spans. This means that our website will be more discoverable by clients. How Now that we know that Semantic HTML is extremely important, we have to learn how to apply it in old and new projects. There are a total of 13 semantic tags, however, the most used are article, aside, footer, header, nav, and secti...

Semantic elements are one of the most significant introductions in HTML5. In the previous versions of HTML, the generic id or class attribute was used for structuring a web page. For example, for defining sidebars, footers, menu or other structural blocks, the tag was used with the corresponding meaning ( div class="footer"). Semantic elements in HTML have intrinsic meaning and convey that meaning both to the browser and the developer. They clearly define what kind of content they contain (for example, the ). Let’s have a look at semantic elements and their meaning.
