<h2>Common mistakes and misconceptions about modern HTML</h2>
<h3>Treating semantic tags as mere styling hooks</h3>
<p>We have all been there: you look at a pristine <code><article></code> or <code><section></code> tag and think, "Ah, this is just a fancy <code><div></code> with better branding." Let us take a strong position right here—if you are choosing your HTML elements based solely on how easy they are to target with CSS rather than what they actually mean, you are building a house of cards. Semantic HTML is not a stylistic suggestion; it is the fundamental contract between your content and assistive technologies. Sure, we don't always get every single aria attribute or landmark role right on the first draft—web standards can feel like moving targets—but treating markup as an afterthought is a lazy shortcut we need to leave behind.</p>
<h3>Overusing non-semantic generic containers</h3>
<p>Div-soup is the digital equivalent of sweeping dirt under the rug. You might think nesting ten <code><div></code> elements deep to center a single button is harmless, but browsers and screen readers beg to differ. We often hide behind the excuse that modern frameworks make component-based nesting inevitable, but that is a cop-out. Writing clean structure requires discipline, and while we admit that refactoring legacy templates can sometimes test your patience to its absolute limit, settling for lazy markup creates a maintenance nightmare for whoever inherits your code tomorrow.</p>
<h2>Little-known aspect or expert advice</h2>
<h3>Why native document structure beats automated shortcuts</h3>
<p>Most developers rely entirely on automated linters and accessibility extensions to validate their pages, missing a crucial secret: automated tools only test code, not human context. True semantic mastery lies in understanding how the browser constructs the implicit accessibility tree from raw DOM nodes. When you thoughtfully sequence your heading hierarchy—from <code><h1></code> down to <code><h6></code> without skipping steps—you give screen-reader users a reliable map of your page before they read a single sentence. We tend to obsess over pixel-perfection in design mockups while completely ignoring the invisible architecture that actually makes the web accessible. Master the raw document outline first, and your CSS will effortlessly fall into place.</p>
