I want to share some insights on a crucial aspect of web development that often gets overlooked especially for those just starting out and that is HTML Validation.
As a beginner myself, I found that many resources don't always highlight the importance of using an HTML validator. We're often more focused on writing the code and seeing the outcome--getting the site to look and function correctly.
In the world of web development, writing clean, efficient and error-free code is essential for building functional websites. To ensure your HTML code is well structured and free of errors is by making use of HTML Validaton service. This service is designed to check your HTML code against standards, helping you to detect and correct issues before they affect your website's performance.
An HTML validator is a tool that checks the syntax of your HTML code against standards set by the World Wide Web Consortium (W3C). The validator scans your HTML code for errors, warnings and ensures that the code complies with best practices for web accessibility and Search Engine Optimization (SEO)
Reasons using HTML Validator is important:
📌 Catches common syntax errors like missing tags, misplaced attributes and unclosed elements helping to prevent broken pages or unexpected behaviour on the site.
📌 Enhances web accessibility, ensuring that websites can be accessed by people with disabilities using screen readers or other assistive technologies.
📌 It can potentially improve website's search engine ranking.
📌 It can identify issues that might cause websites to display incorrectly in some browsers.
How to use HTML Validation service
👇
Step 1: Access the HTML validator
● Open the HTML validator in your web browser i.e go to https://validator.w3.org/
Step 2: Choose the Validation method
✅️ File Upload - If you have an HTML file stored locally, you can upload it directly to the validator.
✅️ URL - If your website is live, enter the URL of the page and the validator will fetch the page's HTML code.
✅️ Direct Code Input - You can copy & paste your HTML code directly into the validator's text box.
Step 3: Start the Validation process
● After providing the HTML code (via file upload, URL, direct input), click the Check button to start the validation process.
Once the validator completes the process, it will present the results. Typically, these results will include:
❌️Errors: Critical issues in your code that prevent it from being valid.
⚠️Warnings: Issues that aren't strictly errors but should be addressed for best practice.
Review all errors and warnings and edit your HTML code to correct them. Once you've addressed all errors and warnings, revalidate the code to ensure it's error-free.
VALIDATE often! don't wait until your project is complete. Regular validation during development helps catch errors early.
