Can you change the color of broken links on your site to distinguish them from working ones? For example, making working links blue and broken links red.
If CSS is not an option, is it possible to use JavaScript to detect broken links and style them differently later on? (Note: jQuery is not an option for me.)
It is not possible to apply CSS styling to a broken link, as the browser does not detect the status of a link until it is accessed by a user or system.
One potential approach could involve using Javascript to attempt to fetch each linked page within the document. If a link fails to load, the script could dynamically alter the link's appearance. However, this method may be inefficient and resource-intensive, especially on mobile devices.
Additionally, accessing links from different domains may be restricted by the browser for security reasons, limiting the effectiveness of the Javascript solution.
A more practical solution would be to have a server periodically check the validity of links on your pages and store this information in a database. The server could then add a class to broken links when rendering the page, allowing CSS to style them accordingly. Server-side processing eliminates same-origin restrictions and provides more reliable link status checks. However, offline evaluations may present challenges, such as temporary server outages or specific internet routing issues.
For more information on this topic, feel free to refer to this helpful post: Javascript: Check if server is online?
By utilizing JavaScript, you have the ability to verify the status of a server to determine whether it is online or offline. With this function, you can also differentiate between good and bad links by displaying them with unique classes.
Although CSS itself cannot directly detect broken links, there are ways to identify and style them visually.
If you have another means of checking for broken links, you can assign a class to those links and apply a unique CSS style to highlight them as broken.
Determining broken links automatically is a separate issue, but there are resources available online to guide you. For example, you can refer to discussions on detecting broken links using JavaScript and PHP. It is recommended to implement a system that periodically checks all links on your site, rather than checking each link for each visitor, to add a class like broken to broken links.
