Does HTML5 produce pages that look the same across all browsers?

HTML5 does not guarantee that web pages will look the same across all browsers. While HTML5 provides a standardized way to structure content, the way browsers interpret and render that content can vary due to differences in their engines, default styles, and implementation of HTML5 features. Factors like CSS support, JavaScript execution, and even various browser versions can lead to discrepancies in appearance and functionality.

For instance, some browsers may not fully support certain HTML5 features or may apply default styles differently, leading to variations in layout and design. Additionally, user settings, extensions, and device resolutions can contribute to the inconsistency in how pages are displayed. Therefore, while HTML5 aims for a more consistent web experience, achieving identical appearance across all browsers is not entirely feasible.

This brings to light the need for careful design and testing across multiple browsers to ensure a more uniform experience for users.
