How do you integrate validation into your web development workflow and tools?

2 How to validate?

Depending on your preferences, needs, and resources, there are various ways to validate your web pages and stylesheets. You could opt for online validators such as the W3C Markup Validation Service or the W3C CSS Validation Service. Browser extensions like HTML Validator or CSS Validator provide a validation icon or button on the browser toolbar with validation results in a pop-up window or tab. Code editors such as Visual Studio Code or Sublime Text have built-in or add-on validation features that highlight errors and warnings while typing or saving. Lastly, command-line tools like HTML Tidy or CSS Lint can be run from the terminal or integrated with a build system or version control system to validate your code automatically or on demand.

3 When to validate?

When it comes to validating web pages and stylesheets, the best time to do so depends on your workflow and goals. Prior to publishing or deploying a web project, you can validate it to ensure it meets the quality standards and requirements of the client, employer, or audience. During development or testing, validating can help catch and fix errors early on. After making changes or updates, validating can verify that the code is still valid and does not introduce new errors. Additionally, you may want to validate periodically or regularly to maintain the validity and quality of your web project, as well as stay up-to-date with web standards and languages.

4 What to validate?

The degree of validation required for web pages and stylesheets is contingent on the complexity and goal of the web project. You can validate the entire project to assess consistency, compatibility, and compliance across all web pages and stylesheets, or you can focus on individual files or components to pinpoint specific errors and warnings. Additionally, you can isolate and test code snippets or blocks that you are editing or adjusting, as well as fine-tune details or parameters that influence the look or functionality of your web elements.

5 How to handle validation errors and warnings?

Validation errors and warnings can vary in terms of importance and urgency. To handle them, you should prioritize and fix those that have a significant impact on the functionality, performance, or accessibility of your web project. Meanwhile, you can ignore or suppress the errors and warnings that are irrelevant, harmless, or unavoidable due to the limitations or variations of the web standards or languages. Finally, if some errors and warnings are deliberate, necessary, or beneficial for your web project (e.g. using experimental features, custom attributes, or vendor prefixes), then you should explain or document them.
