Designing Hyperlinks: Tips and Best Practices
A hyperlink (aka link) is the most basic interface on websites. In fact, we can trace hyperlinks back to the origins of the web, with Tim Berners-Lee’s ENQUIRE, where each new page had to link to another. Links connect all of our content together and come in many forms; from links contained in a paragraph to a list of links that we’ve come to know as navigation menus.
This article is a discussion on designing hyperlinks, offering a few tips and best practices for designing them. We will conclude with a small showcase of exceptional hyperlink designs on live sites.
Why Is Hyperlink Design So Important?
Links are the most basic interactive component between a user and a web page: A user clicks on a link, and in turn, they are presented with another web page. They’re so important, yet easily get lost in the midst of newer and shinier UI elements like web forms, animated tooltips, and call-to-action buttons (which are essentially links styled to look like something else). Links are so ubiquitous that we often overlook them in our designs.
Basic Principles of Designing Hyperlinks
Before we go any further, it might be wise to cover basic things you should know about hyperlinks.
When conceptualizing link designs, it’s important to consider and know the link states you have to work with. There are 5 states that
<a> elements can have:
a:link– this is the normal state of a hyperlink
a:visited– this is when the link has been visited before
a:hover– this is when the user hovers their mouse over a link
a:active– this is when the user clicks on the link (or presses the Enter key on a focused link)
a:focus– this is when the user uses the Tab key to navigate to hyperlinks
The technical term for these states is pseudo-classes. It’s important to note that web browsers treat these states differently by default. For example, in Firefox,
:focus are displayed with a dashed gray border around them, controlled with the
outline property. Whereas, in Google Chrome (and other WebKit browsers),
:active links will have no style and
:focus links will have a yellow border around them by default.
Here are examples of each link state (shown in Google Chrome 6.0):
It’s best to have a style for each state so that the user is aware of the status of each hyperlink on a web page. For example, hovering over a link and having it look a different way (e.g. changing its color) improves the perception that it can be clicked.
Popular CSS Properties for Styling Hyperlinks
There are many link style properties you can take advantage of for designing hyperlinks. Some popular CSS properties pertaining to the visual appearance of links include:
color– The color of the hyperlink
text-decoration– Setting this to
noneremoves the default underline
background-color– If used in the
:hoverstate, can make the link’s background color change
outline– Setting this to
a:focusedselector removes the default gray border around active and focused links in Mozilla and the yellow or blue border in WebKit (Chrome and Safari); this is not advised because the border helps with web accessibility
font-weight– Another distinguishing method for hyperlinks is setting them to bold
border– If you need more control outside of
text-decoration: underline, try giving your hyperlinks a bottom border (experiment with thickness, color and style)
There are plenty more of CSS properties you can tweak, but the above seems to be the most common.
Below, you can see different styles of hyperlinks on Flickr. The text "Your Photostream" changes
background-color when you hover over it. The main menu links are styled as bolded and without underlines. The "Recent Activity" link looks the most like the standard blue, underlined hyperlink.
Hyperlink Design Best Practices
Here are a handful of suggestions and commonly held best practices when dealing with the style and design of hyperlinks.
Keeping Link Styles Simple Isn’t a Bad Thing
I think we can all still relate to seeing the standard blue, underlined hyperlink. It’s the default style of hyperlinks and they work well.
Good hyperlinks should be distinctive from other types of text in a web page. According to several findings by usability researcher Dr. Nielsen, hyperlinks are most effective when they are a different color from other types of text in a web page and when they are underlined to denote that the text is clickable. Nielsen also suggests that the color of unvisited links should be "vivid, bright, and saturated." It goes without saying that the converse of these ideas are also true. It’s best to avoid underlining text for things other than links, and not using normal text that is the same color as your links.
Style Link States Differently
Earlier on, we talked about the 5 different link states. To avoid confusing your users and to speed up visual recognition of hyperlinks on a web page, it’s best to provide different styles for each link state.
Don’t Remove Outlines on Active and Focused Links
By default, most browsers will style hyperlinks when they are clicked or focused on. For example, in Firefox 3.6, the default style for
a:active is coloring the link red and surrounding it with a red dashed outline. The default style for
a:focus, which you can see for yourself by using your Tab key, is a blue dashed outline.
Both of these visual elements are used to aid in accessibility. People who cannot use a mouse need to tab to hyperlinks in order to activate them (using the Enter/Return key). Imagine having to tab through 100 links in a web page (which is not as uncommon as you might think, the front page of Six Revisions has over 130 links). Would it not be difficult to see which link you are on if there was no visual cue for them?
The same is true for active links; a different style gives users the visual feedback that they were able to successfully click on the link.
Keep Hyperlinks Consistent
Many principles of usability and psychology support the notion that things that are similar in function should look the same. For example, Gestalt psychology — which applies to human perceptions of design — suggests the concept of similarity; that is, "[w]e group things perceptually if they appear similar to one another."
To avoid the situation where users having to think whether a particular text is a link or not, it is a good idea to keep hyperlinks and regular text styled consistently.
Reserve Common Hyperlink Styles for Hyperlinks
The accepted and most recognizable convention for hyperlinks is that it is blue and underlined. Therefore, to avoid confusion, you should avoid coloring your normal text as blue and underlined.
