CSS Interview Workbook: 108 Questions with Model Answers, Follow-ups and Drills

The only CSS workbook you will need.

CSS interviews don't stop at the definition. The interviewer asks a follow-up, then asks you to tie it to something you've built. This workbook prepares you for all three.

What's inside

• 108 questions covering every concept interviewers draw from
• A model answer for each, covering the tradeoff and not just the definition
• The follow-up an interviewer is likely to ask next
• A drill for each question that you answer from your own work, in fillable boxes inside the PDF
• A concept map at the front showing all thirteen areas at a glance
• Three levels: 36 Foundation, 46 Intermediate, 26 Senior
• A coverage table mapping every concept to its question

The thirteen sections
