Most Common Bugs and issues When making a website

If you are a web developer, you know how frustrating it can be to encounter bugs when making a website. Bugs are errors or defects in the code that prevent the website from functioning properly or displaying correctly. Some bugs are easy to fix, while others can take hours or days to debug.


In this blog post, we will look at some of the most common bugs when making a website and how to avoid or fix them.


1. Broken Links


Broken links are links that lead to non-existent or inaccessible pages. They can cause frustration for users and damage your website's reputation and SEO ranking. Broken links can occur due to various reasons, such as:


- Typing errors in the URL


- Moving or deleting pages without updating the links

- Changing the domain name or hosting provider

- External websites changing or removing their pages


To avoid broken links, you should always check your links before publishing your website and use relative URLs instead of absolute URLs whenever possible. You should also use a tool like [Broken Link Checker](https://www.brokenlinkcheck.com/) to scan your website for broken links regularly and fix them as soon as possible.


2. Cross-Browser Compatibility Issues


Cross-browser compatibility issues are problems that arise when your website looks or behaves differently on different browsers or devices. They can affect your website's usability, accessibility, and user experience. Cross-browser compatibility issues can occur due to various reasons, such as:


- Using outdated or non-standard HTML, CSS, or JavaScript code

- Using features that are not supported by all browsers or devices

- Not testing your website on multiple browsers or devices


To avoid cross-browser compatibility issues, you should always follow the web standards and best practices for writing HTML, CSS, and JavaScript code. You should also use tools like [Can I Use](https://caniuse.com/) to check the browser support for different features and [BrowserStack](https://www.browserstack.com/) to test your website on various browsers and devices.


3. Responsive Design Issues


Responsive design issues are problems that arise when your website does not adapt to different screen sizes and orientations. They can affect your website's layout, navigation, readability, and user experience. Responsive design issues can occur due to various reasons, such as:


- Not using a responsive framework or template

- Not using media queries or breakpoints

- Not using relative units or flexible layouts

- Not optimizing images or videos for different resolutions


To avoid responsive design issues, you should always use a responsive framework or template for your website, such as [Bootstrap](https://getbootstrap.com/) or [Foundation](https://get.foundation/). You should also use media queries or breakpoints to adjust your website's style and layout according to different screen sizes and orientations. You should also use relative units or flexible layouts to make your website fluid and scalable. You should also optimize images or videos for different resolutions using tools like [TinyPNG](https://tinypng.com/) or [Cloudinary](https://cloudinary.com/).


4. Form Validation Issues


Form validation issues are problems that arise when your website does not check the input data from users before submitting it to the server. They can affect your website's security, functionality, and user experience. Form validation issues can occur due to various reasons, such as:


- Not using proper input types or attributes

- Not using client-side or server-side validation

- Not providing clear and helpful error messages

- Not sanitizing or escaping the input data


To avoid form validation issues, you should always use proper input types or attributes for your form fields, such as [email](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/email) or [number](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/number). You should also use client-side or server-side validation to check the input data for errors or malicious code before submitting it to the server. You should also provide clear and helpful error messages to guide users on how to correct their mistakes. You should also sanitize or escape the input data to prevent SQL injection or cross-site scripting attacks.


5. Performance Issues


Performance issues are problems that arise when your website takes too long to load or respond. They can affect your website's SEO ranking, user satisfaction, and conversion rate. Performance issues can occur due to various reasons, such as:


- Having too many or large files or requests

- Not using compression or caching techniques

- Not minifying or bundling your code

- Not using a content delivery network (CDN)


To avoid performance issues, you should always reduce the number and size of files or requests on your website using tools like [PageSpeed Insights](https://developers.google.com/speed/pagespeed/insights/) or [GTmetrix](https://gtmetrix.com/). You should also use compression or caching techniques to reduce the bandwidth and loading time of your website using tools like [Gzip](https://www.gzip.org/) or [Cloudflare](https://www.cloudflare.com/). You should also minify or bundle your code to remove unnecessary spaces, comments, or characters using tools like [UglifyJS](https://github.com/mishoo/UglifyJS) or [Webpack](https://webpack.js.org/). You should also use a content delivery network (CDN) to deliver your website's content from the nearest server to the user's location using services like [Amazon CloudFront](https://aws.amazon.com/cloudfront/) or [Akamai](https://www.akamai.com/).


Conclusion


These are some of the most common bugs when making a website and how to avoid or fix them. By following these tips, you can improve your website's quality, functionality, and user experience. However, this is not an exhaustive list of all the possible bugs that can occur when making a website.
