Deprecated HTML elements (and what to use instead)

Change is a constant in technology, and staying updated with the latest developments is crucial to avoid potential issues, especially with HTML5, which has deprecated several elements in favor of more modern alternatives. The guide discusses deprecated HTML elements such as `<marquee>`, `<acronym>`, `<basefont>`, `<blink>`, `<dir>`, `<frame>`, `<strike>`, and `<center>`, suggesting CSS-based alternatives for each to ensure better functionality and accessibility. For instance, CSS animations can replace `<marquee>` for scrolling effects, and `<abbr>` can substitute `<acronym>`. The guide emphasizes the importance of using current web standards to maintain codebases that are robust and forward-compatible, noting that while these deprecated elements may still function, they could be unsupported in the future. It also highlights the role of CSS in providing presentational styles, which HTML elements should not handle, and urges developers to adopt best practices to prevent future technical debt.
