How to use a base tag in html5 and where to use and in which tag we have to use

Answer 1

When we are rewriting urls.

If I link files like this which is not good
img/img.jpg
css/style.css

And we rewrite the url of the file that uses these.

/profile.php

For example we rewrite the url of the above profile file with .htaccess to look like this

/user/{user_id}/

Now when you access that url, it will request all other sources based on it.
For example

/user/{user_id}/img/img.jpg
/user/{user_id}/css/style.css

Those doesn't exist.
We can prevent that with the base tag. It will request all other sources based on it, not the actual url.

I would fix that by adding this to the profile.php header

<base href="http://localhost/">

there's no use for that.
Start your paths with slash "/". And It requests it from the root directory
