<p data-start="74" data-end="368">Making your web apps accessible is not optional &mdash; it improves usability for everyone, helps your products reach more people, and signals professional craftsmanship to employers. This short, practical guide gives the key accessibility wins you can add to any React + Node project in a few hours.

<p data-start="370" data-end="663">If you want guided, hands-on help building accessible apps and polishing projects, consider <strong data-start="462" data-end="554">full stack classes in Mumbai or a mentor-led <strong data-start="571" data-end="662">full stack course in Mumbai.

<h2 data-start="670" data-end="718">1) Start with semantic HTML (the biggest win)</h2>
<ul data-start="719" data-end="969">
<li data-start="719" data-end="869">
<p data-start="721" data-end="869">Use real elements: <code data-start="740" data-end="750"><button></code> for clickable controls, <code data-start="775" data-end="783"><form></code> for forms, <code data-start="795" data-end="804"><label></code> for inputs, <code data-start="817" data-end="824"><nav></code> for navigation, <code data-start="841" data-end="849"><main></code> for main content.
