/* .error Class:

This defines a CSS class named .error. Any HTML element with this class applied will be affected by the animation.
2. animation Property:

This property is used within the .error class to specify the animation to be applied.
Here's the breakdown of the values used:
shake: This refers to the name of the animation defined using the @keyframes rule (explained later).
0.1s: This sets the duration of the animation to 0.1 seconds (100 milliseconds).
linear: This defines the timing function of the animation. In this case, linear creates a constant speed throughout the animation. Other options include ease-in, ease-out, or ease-in-out for different pacing effects.
10: This specifies the number of times the animation should repeat. Here, it's set to repeat 10 times.
3. @keyframes shake Rule:

This rule defines the actual animation named shake that was referenced in the .error class.
It uses percentages to define the animation's behavior at different points in time (0%, 25%, 50%, 75%, and 100%).
Inside the rule, the transform: translateX(value) property is used to move the element horizontally. The value specifies the amount of horizontal movement.
Here's how the animation works:
At 0%, the element is at its original position (translateX(0)).
At 25%, the element moves slightly to the left by 2 pixels (translateX(-2px)).
At 50% (midpoint), the element returns to its original position (translateX(0)).
At 75%, the element moves slightly to the right by 2 pixels (translateX(2px)).
At 100%, the element returns to its original position (translateX(0)) again.*/
