Cross‑browser Compatibility
When I started in web development (twenty‑three years ago), cross‑browser compatibility was a hot topic. Many days and hours were lost cursing Microsoft for interpreting the specs differently to other browsers, and a lot of money could be made if you were fluent in these issues. Nowadays, these issues tend to stem more from differing levels of compatibility with new JavaScript features (with iOS Safari being a prime suspect), rather than with CSS.
Below you will find a subset of articles from my blog specifically about Cross‑Browser Compatibility. This is an area I have worked with for many years, and it has been a regular subject in my writing. There are twenty‑five articles collected together for you below.
