-o-animation: move_eye 4s linear 0s infinite alternate; /* Apply animation to the eye for Opera browsers */
animation: move_eye 4s linear 0s infinite alternate; /* Apply animation to the eye for other browsers */
}
@-webkit-keyframes move_eye { from { margin-left:-20%; } to { margin-left:100%; }  } /* Define keyframes for animation in webkit browsers */
@-moz-keyframes move_eye { from { margin-left:-20%; } to { margin-left:100%; }  } /* Define keyframes for animation in Firefox browsers */
@-o-keyframes move_eye { from { margin-left:-20%; } to { margin-left:100%; }  } /* Define keyframes for animation in Opera browsers */
@keyframes move_eye { from { margin-left:-20%; } to { margin-left:100%; }  } /* Define keyframes for animation in other browsers */
</style>
</body>
</html>

Explanation:

The HTML document contains a container div with a class of "animation" and two child divs: one for text content and another for an animated eye.
The text content div has a class of "w3r" and contains the text "w3resource Tutorial".
The animated eye div has a class of "cylon_eye" and is styled with a gradient background and animation properties.
CSS is used to define animations for the eye movement (@keyframes move_eye) and apply them to the eye element.
The animation causes the eye to move horizontally from left to right infinitely.
