Restrictions With Hyperlinks

Whether you’re familiar with computer languages or not, chances are you’re very familiar with hyperlinks as they’re found on nearly all websites. Hyperlinks are written in HTML and come in several flavors – from blue underlined words to clickable images. Although rarely encountered, sometimes users or web-designers will encounter restrictions involving hyperlinks.

Restricted to HTML

The first restriction involving hyperlinks is that they are restricted to HTML coding. Hyperlinks can’t be created through programming languages and attempting to do so will result in restrictive lack of functionality. To counter the issue, most programming languages work in conjunction with HTML, allowing them to benefit from its offerings, including hyperlinks.

Must be Included within Tags

When creating HTML code, a common problem – especially for those new to the language – is not tagging hyperlinks correctly. All hyperlinks are tagged with an identification code, known as an <a href> link. This link signifies where the hyperlink should start. The end point of the hyperlink must also be pinpointed correctly to avoid restrictions on its use. An entire code will look similar to: “<a href=”URL”> text</a>. The equal sign points to the URL that the link will lead to, while the area labeled “text” will be the text featured in the link. The “</a>” signifies the ending point of the link. With a few minor adjustments, the link can use images as well.


Sometimes link restrictions are placed upon hyperlinks within emails. Some hyperlinks within emails can be dangerous, as clicking them causes viruses to download to your computer. Internet browsers counter this by placing restrictions on opening hyperlinks in emails. In this case, most browsers ask you to confirm that you want to open the link prior to the link becoming functional.


A common bug found within the registry on a computer causes a message to pop up telling the user that the hyperlink won’t open due to restrictions. Usually occurring for Internet Explorer users who are attempting to use Microsoft Outlook, the fault is that of a corrupted registry file. The usual solution involves opening Internet Explorer, going to settings and re-setting it to default.
