Heading Tags
Headings range from level one down to level six, establishing a clear hierarchy within documents. The primary heading introduces the main subject of the page.
Subheadings and Sections
Lesser headings break large blocks of text into manageable sections. Strong emphasis is applied using specific elements rather than forbidden formatting styles.

Common mistakes to avoid when building modern web pages
Developing clean, accessible, and high-performance websites requires careful attention to detail. Even experienced developers occasionally fall into common traps that compromise user experience, search engine optimization, and code maintainability. Recognizing these frequent missteps is the first essential step toward writing more robust and reliable code.
1. Neglecting semantic HTML elements
One of the most frequent errors is overusing generic <code><div></code> and <code><span></code> tags for every layout requirement. Semantic tags such as <code><header></code>, <code><nav></code>, <code><main></code>, and <code><footer></code> provide vital context to screen readers and search engines alike. Failing to utilize them correctly degrades accessibility and makes your document structure difficult to parse automatically. Always choose tags that accurately describe the specific content they contain.
2. Ignoring Mobile-First responsive design principles
Designing exclusively for large desktop viewports and attempting to scale elements down afterward frequently results in broken layouts and sluggish mobile performance. Because a significant portion of modern web traffic originates from mobile devices, neglecting flexible grid systems, responsive media queries, and touch-friendly interactive targets alienates users. Prioritizing a mobile-first approach during your initial styling phase ensures fluid scalability across all screen sizes.
3. Overlooking core accessibility (a11y) standards
Accessibility is too often treated as an optional afterthought rather than a fundamental requirement. Common oversights include missing alternative text on informative images, insufficient color contrast ratios between text and background layers, and broken keyboard navigation pathways. Integrating accessibility standards from the very beginning of the development cycle guarantees compliance with modern regulations and creates an inclusive experience for every user.
