Q: What are some best practices for writing HTML code?
A: Some best practices for writing HTML code include using semantic HTML to provide meaning and structure to the content, using valid and well-formed HTML syntax, using appropriate indentation and commenting to improve readability, optimizing page load times by minimizing the use of external resources and optimizing images, and following accessibility guidelines to ensure that the content is accessible to all users, including those with disabilities.
Q: What are some common accessibility issues in HTML code?
A: Some common accessibility issues in HTML code include using images without alternative text, using non-descriptive link text, using tables for layout purposes, using low contrast colors, and not providing keyboard accessibility for interactive elements such as forms and buttons. Addressing these issues can help improve the accessibility of a web page and make it more usable for all users.
