Angular - Animations

Identify the error in this Angular animation code snippet:

trigger('fadeIn', [
  transition(':enter', [
    animate('1s', keyframes([
      style({ opacity: 0, offset: 0 }),
      style({ opacity: 1 })
    ]))
  ])
])

AIncorrect trigger name syntax

Banimate duration should be a number, not a string

CMissing offset value in second style inside keyframes

Dtransition selector ':enter' is invalid

Step-by-Step Solution

Solution:

Step 1: Check keyframe style objects for offsets
Each style in keyframes should have an offset between 0 and 1 to define timing precisely.
Step 2: Identify missing offset
The second style lacks an offset property, which is required for keyframes to work correctly.
Final Answer:
Missing offset value in second style inside keyframes -> Option C
Quick Check:
All keyframe styles need offset [OK]

Quick Trick: Every keyframe style needs an offset between 0 and 1 [OK]

Common Mistakes:

Omitting offset in some keyframe styles
Using wrong transition selectors
Passing duration as number instead of string
