The code snippet presents an exciting way to add a neon glow effect to text using HTML and CSS, creating an animation that makes the text appear as if it’s pulsating with a neon light. It starts with a simple HTML anchor tag, styled to transform the appearance into an eye-catching neon effect. The CSS part is where the magic happens, employing @keyframes to animate the text’s glow. This animation creates a dynamic visual by alternating the intensity and spread of the text’s shadow, mimicking the flickering of a neon sign.

The CSS code uses text-shadow in combination with keyframes named neon to achieve this effect. It specifies a range of shadow effects that vary in size and intensity, transitioning smoothly from a more spread out and intense glow to a subtler one. This is done using the from and to properties within the keyframes, which dictate the starting and ending states of the animation, respectively.

Moreover, the use of -webkit-, -moz-, and -o- prefixes before animation and @keyframes ensures cross-browser compatibility, allowing this beautiful glow neon text effect to work across different web browsers. This attention to detail ensures that the neon text animation can be enjoyed by a wider audience, regardless of their browser choice. The inclusion of a custom font from Google Fonts further enhances the visual appeal, making the neon effect even more pronounced and stylish.
