Solve the problem that the default value of CSS3 transition-delay attribute is 0 without unit and it is invalid

Today I would like to share with you the CSS3 transition-delay attribute default value 0 without unit is invalid [problem solved], I hope it can help you.

The transition-delay in CSS3 uses a default value of 0. According to the front-end code specification, it is best to use 0 without any units, such as: margin: 0;padding: 0; etc. instead of padding: 0px; margin: 0px;

So when I used transition-delay, I also used transition-delay: 0; and then problems occurred.

Directly on the picture:

If no unit is specified, the default value is 0.

If no unit is specified, the default value 0 is used.

I checked it over and over for a long time and then began to doubt my life. I don’t know why I added the unit. It actually achieved the effect I wanted.

Add units to the default value of 0

Summary: Actually, the two effects are not a big problem. But in fact there is still a big difference. Because it is an animated effect, I personally think that as long as the movements are regular and not weird, it is acceptable. However, if transition-delay is used in a real project and fails to achieve the desired effect for the user or company, then the loss outweighs the gain. It is unclear whether this will happen with other new properties in CSS3.
