Well, as you might expect, “It depends”. For some things, you may be able to take advantage of hooks to modify the output of plugins, themes, and WP core. For other things, you may need to create a child theme to override parts of your theme.

If you modify core, don’t. Ever. Just don’t.

If you modify a theme the mods will be wiped out with each update, so you’d child theme.

What’s one concrete example?

thanks so much for information.
while designing a blog I have tried to make the textarea to the comment form under the name. I already did with a function I have found.

but I am still thinking what if I want to add html input in the comment form that does not exist such as country drop down menu, so I think I need to edit html in the comment form.

There are plugins the allow you to customize the comment forms, as well as plugins that enable 3rd party comment systems. Or, as comments are typically part of a theme, you could child theme that. However, something like that should ideally be theme-independent. If you want to do it yourself, I suggest doing it as a plugin.

@sterndata

thanks for the reply. but I have used many plugins on the theme. what is the maximum number of plugins could I use in landing page with blog? I feel it has become slow

There is no maximum.

Again, child theme or plugin. It depends.
