It’s crucial to consider accessibility while planning and developing websites for all audiences. For example, ensure that websites are accessible to blind or visually impaired individuals due to the graphic and complex nature of web pages.
Any website may be given access to users of assistive devices like screen readers with a little extra effort on the back end. By investing in online accessibility, you guarantee a great user experience for everyone and demonstrate to your audience that you care about their ability to access your material equally. And it all begins with looking at the HTML code that makes up your website.
What Is Semantic HTML and Why Is It Important?
Semantic HTML, also known as semantic markup, is HTML that adds value to the web page as opposed to focusing solely on presentation.
The study of linguistic meaning is called semantics. In language, these would be the words we use to express ourselves, and in HTML, they would be the tags we use to identify a document.
The advantage of creating semantic HTML comes from the desire to communicate, which ought to be the main objective of any web page. Therefore, your paper will have more information under the semantic tags you provide, which improves communication.
Semantic tags help the browser understand the purpose of a webpage and its content. As a result, search engines are informed of this clarity, ensuring that the appropriate pages are delivered in response to the appropriate requests.
A sizable number of users only use the keyboard to browse the internet and rely on screen reader programs to assist them in navigating.
Therefore, it is crucial to check that each element can be accessed using the keyboard and that readers can read it. We must code to support all users. To ensure that all users can easily browse it, semantic HTML uses the proper tags for each element in addition to the new semantic tags.
Your SEO positioning may be impacted either favourably or unfavourably depending on elements like the site’s accessibility, “responsive” design, or content writing style.
HTML and Accessibility Guidelines
You can start using accessibility in your workflow by using the guidelines listed below. This will help to give your users more of your attention.
Pay Attention to Headings
Users will better grasp the layout of your website and the connections between different sections if you utilise headings <h1> through <h6> to provide a clear outline. Additionally, it will make navigation easier for users of assistive technology. There are several ways to move from one piece of information to another while using screen readers.
Specify the Language Being Used
There are many advantages to letting the browser know what language is being used on your page. It benefits SEO and makes it easier for browsers and third-party translation software to find the appropriate language and dictionary. The right voice profile or approach can be selected by assistive technology by specifying the right terminology on an HTML page.
You should always choose genuine native HTML elements over creating your own. For instance, rather than using a div when a button is required, use the button element.
Developers should use buttons because
- By default, buttons have a more appropriate appearance.
- A screen reader recognises them as a button.
- They are more focusable and clickable.
A button is also available for those who only use their keyboards for navigation; users can click it with both mouse and keys.
Use Clear Language
Always speak in plain, understandable language. Also, try to avoid characters that a screenreader cannot read well. For instance:
- Keep your phrases as brief as you can.
- Use fewer dashes. For example, you should put 5 to 10 instead of 5-10.
- Avoid using acronyms. For example, date of birth should be used in place of DOB.
- Avoid using slang and derogatory language.
The use of HTML5 to markup thematic divisions is recommended. Additionally, WAI-ARIA role attributes can be used for older browsers or areas like the search that lack explicit tags. The <div> element is not replaced by sectioning elements. Apply them to markup longer, related passages that stand alone from other content. Avoid using sectioning tools excessively. Use sections for semantics and <div> for CSS/JS-only purposes.
Users of screen readers will be able to navigate web pages by hopping from section to section, which is one of the key advantages. Landmarks are these travelable areas.
Alt Tags in HTML Accessibility
Images on a page may have alt tags that explain their appearance or purpose. When an image fails to load, the alt tag displayed in its place is searched by search engine bots and is read out loud by screen readers in use by visually impaired people. Alt tags, also referred to as “alt attributes,” “alt descriptions,” or “alt tags,” are utilised in an HTML code or the relevant Content Management System.
A web accessibility tenet is the addition of alternative tags to photographs on your website. In the event that an image file cannot be loaded, alt tags will be shown in their place.
Search engine crawlers can index and rank images correctly in image searches with the help of richer image context and descriptions provided by alt tags. Additionally, it gives search engines contextual data about the page’s content.
Tips for creating good ALT tags:
- Alt tags should be limited to 125 characters or fewer. Popular screen readers are known to terminate alt tags after about 125 characters. Although it is no longer an absolute requirement, it is nevertheless a useful reference for SEOs and content producers.
- The primary purpose of alt tags is to offer text descriptions of images for viewers who cannot see them. If an image is purely aesthetic or is only included for design reasons and does not transmit any meaning or value, it belongs in the CSS and not the HTML.
- You have a second chance to use your target term on a page with alt tags, giving you a chance to tell search engines that the page is extremely relevant to a specific search query. While explaining the image and giving it, context should come first. If it makes sense, put the keyword in the alt tags of at most one image on the page.
Accessible Rich Internet Applications is referred to as ARIA. To make website content and applications available to individuals with disabilities who use assistive technologies, you can add a set of attributes called ARIA to HTML components (AT). ARIA can fill in the gaps when accessibility problems can’t be handled with native HTML.
The semantics that can be assigned to components are defined by ARIA, and they are broken down into roles (definitions of different categories of user interface elements) and the states and attributes that each role supports. Unless an element already has acceptable ARIA semantics, authors must provide the element with an ARIA role, the proper states, and the necessary attributes during its life cycle.
These are the roles that the browser uses, per the official W3C standard. They serve as the cornerstone for all other WAI-ARIA responsibilities. Because abstract roles are not supported in the API binding, content developers must not utilise them. Widget, landmark, command, etc., are a few examples of abstract roles.
In HTML, instead of focusing only on presentation, semantic tags give the web page meaning. A semantic tag makes its meaning plain to the developer and browser. Semantic tags have several benefits over non-semantic tags, including the fact that they greatly aid screen readers and optimise the code.
HTML Semantic tags describe the actual content instead of merely how the browser will display it. Semantic elements are where both the developer and the browser can easily understand the meaning of a semantic element.
Contrary to semantic elements, non-semantic items are meaningless. They offer no information regarding the information they contain. To mark up semantics shared by a group, they can be combined with various properties.
HTML The browser can better understand a page’s purpose and content with the aid of semantic tags. Semantic tags also aid in SEO since they make the material more adaptable, which makes it easier for browsers to understand.
For those who use screen readers, semantic elements are quite helpful. Screen readers can more effectively distinguish between the various sections of a website because of the extra information supplied by semantic tags.
Weblinks that are camouflaged as descriptive language and direct users to other websites are known as descriptive hyperlinks.
It is simple for the individual to navigate when you utilise descriptive language because a screen reader will read every character and dash of the URL. Including descriptive hyperlinks in your documents helps keep them organised and simple to read.
Selecting the words to link should be done with care when establishing text-based links to a webpage. Generally speaking, you should always link keywords.
Using keyword links will:
- Assist in enhancing search engine optimisation.
- Give customers extra information.
- Give context to people using a screen reader or assistive technology who don’t have working eyes.
Tips for writing hyperlinks:
- A URL should not be used as the link text, particularly if it is lengthy or complex. If the whole URL is lengthy, users can use a URL shortener to make links to the same material considerably shorter. Have included a short link to the complete document if your document contains several links so that users only need to physically type in one URL.
- Connect at least one whole word. Usually, two words are preferable.
- Keep related statements as concise as you can while maintaining their meaning when read in isolation because fewer words will have to be spoken, and screen reader users will benefit.
Like many other areas of web creation, accessibility is better taken into account upfront rather than as an afterthought. You can avoid page redesigns later by implementing accessible best practices right away.
People with impairments may face substantial obstacles as a result of poor design. They are included for this reason. Usability is demonstrated, for instance, through specific guidance and feedback for website applications. They also support those with learning and cognitive difficulties. Without them, some persons with impairments might not be able to use the Web.
Web pages, however, are merely text documents that may be modified at the most fundamental level. You may immediately enhance the surfing experience for visitors that require it with a little more tinkering and a few accessibility checks. Continue with other content-related adjustments that benefit your visitors after that.
To design a site that works for everyone, accessibility, usability, and inclusiveness must all be taken into consideration. Their objectives, strategies, and principles strongly concur. When creating websites and apps, tackling them all at once is usually beneficial.
