Let's look at specific examples.

"margin:0auto;" does not work for inline-block.

Even if you can first specify "inline-block" with a numeric value, using "margin:0auto;" to center does not work.

"text-align:center;" does not make the parent element a selector

The basic rule of "text-align:center;" is "selector is the parent element". In the above example, if you want to center it, you must create a parent element.

Once you understand the above, you can solve it.
