What are the best practices for testing the semantics of your HTML code?

Testing the semantics of your HTML code involves ensuring proper use of tags for content structure. Best practices include using tools like WAVE or Axe for accessibility checks, conducting manual inspections, and validating against W3C standards.

Validating your HTML code is a web dev must-do. These services (like W3C's) check your code against official standards, identifying errors that could cause problems for users. Why is it important? - Standards Check: Ensures your code follows W3C guidelines, reducing issues across browsers. - Accessibility Boost: Valid code works better with assistive technologies for users with disabilities. - Early Error Catch: Finds errors early in development, saving you time fixing them later. Remember, validation is a step, not the finish line for accessibility. But it's like a check-up for your code, promoting a smooth experience for all visitors.

la validación de tu code no garantiza la accesibilidad, pero es una parte esencial para garantizar que su HTML sea semánticamente correcto.

You should reference the great tools provided by W3C that can check your HTML to determine if it's valid. This would the most fundamental check for HTML validity.

HTML Quality Check: Easy Ways to Ensure Your Web Content Makes Sense" 1-Check Your Code: Use tools like W3C Markup Validator to make sure your HTML is clean. 2-Listen Up: Test how screen readers read your page to ensure accessibility. 3-Make Sense: Look over your code to ensure you're using the right tags for the job. 4-See for Yourself: View your website to see if it looks right and makes sense. 5-Test Everywhere: Make sure your website works well on all browsers. 6-Ask Around: Get feedback from people using your website to make sure it's easy to use.

Best Practices for Using ARIA Roles: - Many HTML5 elements have built-in accessibility features. Use native elements like <button>, <nav>, <main>, and <header> wherever possible. They are more semantically meaningful and have inherent accessibility features that ARIA roles may not fully replicate. - Use ARIA roles to enhance elements that lack the necessary semantic information. For example, if you are using a <div> to create a button for styling purposes, add role="button" to ensure it's recognized as a button by assistive technologies. - Do not add ARIA roles that duplicate the semantics of native elements. For example, avoid role="button" on an actual <button> element.

ARIA roles should be the last resort where existing HTML elements lack the semantics you need. Using the to add button semantics to a <div> tag is unwise, as <button> and <input type="button"> already exist. However, using them to create more complex elements that don't exist (such as a tree navigation menu) is where ARIA roles can really shine.

Using a screen reader is one of the best ways to test your semantic meaning. I stands to reason that we create semantic markup to convey context and organization of the page for search engines and those with assistive tech and so using those technologies and testing what we create is going to give us the best experience about what others may see.

Before screen reader testing, you can use existing accessibility browser tools to get an understanding of how your DOM is represented in the accessibility tree. The tools built into Firefox are ahead of other browsers in this regard. It's important to note that browser & screen reader combinations vary, so Chrome with NVDA will differ from Chrome with Narrator, JAWS, or VoiceOver. If you are unable to test with all of these, focus on the two most used if possible: JAWS and NVDA, which together have >70% of the screen reader usage share.

Check the document outline to ensure it reflects the logical structure of your content. Use tools like the HTML5 Outliner to visualize the outline and verify that headings and sectioning elements (e.g., <header>, <section>, <article>, <footer>) are used appropriately.

The aXe browser plugin has this check built in, along with many others, to allow better testing of many accessibility concerns that go beyond just the HTML.

Use semantic HTML5 elements to clearly convey the meaning of your content. Elements like <nav>, <main>, <aside>, <figure>, and <time> provide additional context and improve the accessibility and SEO of your website.

While there won't be much SEO impact, the accessibility will improve if these semantic elements are used correctly. Many of them generate what is know as 'landmark' sections on the page, which allows a person to navigate directly to them more easily, instead of needing to scroll/tab through the rest of the content first.

Using semantic HTML5 elements (e.g., <header>, <nav>, <main>, <footer>, <article>, <section>) enhances the meaning and structure of your content. This improves accessibility, SEO, and maintainability. For example, instead of using generic <div> tags for everything, use specific HTML5 elements

Conduct regular manual code reviews to ensure that your HTML follows best practices for semantics. Look for opportunities to replace generic elements like <div> and <span> with more meaningful elements.

Asegúrese de que las tablas se utilizan para datos tabulares y no con fines de dise?o, y de que los formularios están etiquetados correctamente.

A manual code review involves inspecting your HTML code for semantic accuracy, readability, and adherence to best practices. This can catch issues that automated tools might miss. Go through your HTML code line by line. Check if element names accurately describe their content, tags are properly nested, attributes are used correctly, document structure is logical and meaningful.

We can add a section for the end-to-end testing, it is very important to use this to be sure our interface don't have any bug that can anoy the user

En mi opinion, una de las tantas prácticas y caminos recomendables en lo que respecta al codigo que hay detrás de cualquier web, bloque, función usando F12 en dichos sitios y leerlos hasta lograr interpretar cada porción de código como cuando queremos comenzar a hablar otro idioma, cambian las sintaxis pero lo importante es el razonamiento, la decodificación, la lógica
