This article demonstrates creating animated glowing links using CSS3. While a previous article used text-shadow and transparent text for a blur effect, this one leverages text-shadow for a glowing effect on hover or focus. IE9 users will need a newer browser as it lacks text-shadow support.
The effect is achieved with a combination of text-shadow and CSS3 transitions. Let's examine the code.
First, the HTML: A simple link with the class "glow" is used:
<a href="http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b" class="glow">Glowing Link</a>
The CSS starts by defining the initial state and transition properties. The transition is set to 500ms with linear timing for a smooth effect. Vendor prefixes are included for broad browser compatibility:
a.glow, a.glow:hover, a.glow:focus { text-decoration: none; color: http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15baaf; text-shadow: none; -webkit-transition: 500ms linear 0s; -moz-transition: 500ms linear 0s; -o-transition: 500ms linear 0s; transition: 500ms linear 0s; outline: 0 none; }
Next, the glowing effect is defined for the hover and focus states. Two text-shadows, one white and one yellow, are used for a more pronounced effect:
a.glow:hover, a.glow:focus { color: http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bfff; text-shadow: -1px 1px 8px http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bffc, 1px -1px 8px http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bfff; }
A demonstration page (link omitted for safety) shows the effect. Experiment with different text-shadow
and transition properties to customize the animation.
Browser Compatibility Notes:
The effect works well in modern browsers (Firefox, Chrome, Safari). IE9 lacks text-shadow support. Opera supports transitions but may not apply them consistently to text-shadows, resulting in a less smooth animation.
A second set of links in the demo uses a back-lit effect (changing text color to match the background), but this makes text invisible in older IE versions. Modernizr or a text-shadow detection script (example below) can address this:
if (document.createElement("detect").style.textShadow === "") { document.getElementsByTagName("html")[0].className += " textshadow"; }
This technique offers a simple yet effective way to add visual interest to links. Feel free to share your creations!

In JavaScript, choosing a single-line comment (//) or a multi-line comment (//) depends on the purpose and project requirements of the comment: 1. Use single-line comments for quick and inline interpretation; 2. Use multi-line comments for detailed documentation; 3. Maintain the consistency of the comment style; 4. Avoid over-annotation; 5. Ensure that the comments are updated synchronously with the code. Choosing the right annotation style can help improve the readability and maintainability of your code.
