A validator can catch many markup problems, but it cannot decide whether your headings, labels, or link text communicate well.
What makes HTML good?
Good HTML uses features defined by the HTML specification, uses them as intended, and follows the structural rules that let browsers parse the document as its author expects. These qualities help browsers and assistive technologies present content according to the author’s intent, as explained in W3C WAI’s H88 technique.
That means a page can look polished and still have poor HTML. Visual appearance alone does not tell you whether a heading is actually marked as a heading, whether a control can be operated with a keyboard, or whether a screen reader can make sense of the content.
Choose elements for what they mean
Use an HTML element because of its purpose, not because its default appearance happens to suit your design. Headings identify sections, lists group related items, navigation landmarks identify navigation, links take users to destinations, and buttons perform actions. MDN’s guide to HTML and accessibility explains that semantic elements communicate structure and provide built-in browser accessibility support.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Use heading elements for headings rather than text that is merely styled to look large.
- Use list markup when items form a list, rather than relying on line breaks or decorative symbols.
- Use a link when activating it navigates to a destination, and a button when it performs an action.
- Use meaningful page regions to help people understand and navigate the document’s organization.
Prefer native controls to imitations
A real <button> already supports keyboard interaction. A <div> styled to look like a button does not automatically gain that behavior or the same meaning. Native controls are generally the clearer, more dependable starting point; custom behavior can introduce extra accessibility work.
Make the document’s order and language clear
Keep source order logical
Arrange markup so that reading it from top to bottom gives the intended sequence. CSS can reposition items visually, but assistive technologies encounter the document’s source order. A visual layout that presents information in one sequence while the markup presents it in another can make the page confusing to navigate. See MDN’s accessibility guidance and W3C WAI’s accessibility tips.

<html lang="en">The language declaration helps screen readers determine how to pronounce and announce text. MDN documents the root element’s lang attribute, and the WHATWG HTML Standard encourages authors to identify a document’s language.

Make links, images, and form controls understandable
People should be able to understand what content conveys and what each control does. Give informative images useful alternative text, associate a label with each form control, and choose link text that makes sense in context. Make interactive elements usable by keyboard, not just by mouse. W3C WAI summarizes these and related practices in its tips for developing accessible content; MDN also covers link text and form labels.
Use structure to show how a page fits together
Meaningful document structure helps people orient themselves and understand relationships between sections. Use headings and page regions to express organization in the markup, rather than relying on font size, spacing, or other visual styling alone. W3C WAI’s Page Structure Tutorial explains how HTML and WAI-ARIA can support navigation and orientation.

Validate the markup, then review its meaning
Validation is useful for finding structural and parsing errors, including markup that uses undefined features or breaks the rules browsers rely on. But passing a validator does not prove that you chose the right element or that the content makes sense to its users. W3C’s H88 guidance distinguishes checks that tools can help with from judgments that still require human review.
- Run an HTML validator to identify parsing and conformance problems.
- Check whether each element expresses the intended meaning: headings are headings, links navigate, and buttons perform actions.
- Read the page in source order and confirm that the sequence remains understandable.
- Review whether images have appropriate alternatives, form controls have labels, and link text is clear in context.
- Test whether interactive elements can be operated using a keyboard.
MDN’s practical point is that improvement need not be all-or-nothing: “The goal isn’t ‘all or nothing’; every improvement you can make will help the cause of accessibility.”
