What steps should I take to ensure my Bootstrap CSS3 code is error-free and W3C validated?

My customer is requesting that I validate the HTML5 & CSS3 code using W3. I plan on incorporating Bootstrap 3.3.4 into the project, but after including it and checking at , I discovered 32 errors and 142 warnings.

The W3C CSS Validator results for (CSS level 3) display errors (32)

What steps can I take to achieve error-free validation of Bootstrap's CSS3 code?

Answer №1

When using frameworks like Bootstrap, W3C Validator often detects warnings and errors. To ensure a clean result for you or your client, consider checking and using error-free code directly in the website. Unfortunately, this appears to be the most effective solution.

I hope this advice proves useful. If it does, give it a thumbs up!
