The HTML introduction file has no underline difference

<rel=href="Public/bootstrap-3.3.5-dist/css/bootstrap.min.css"  >

No underline '/', the link is directly introduced to the directory under this folder, with an underscore, the introduction of the directory under the site.

<rel=href="/public/bootstrap-3.3.5-dist/css/ Bootstrap.min.css ">

These two URLs are different and the URLs introduced are different.

The file introduced above is: HTTP://LOCALHOST:63342/SPHINX/BLOG/PUBLIC/BOOTSTRAP-3.3.5-DIST/CSS/BOOTSTRAP.MIN.CSS

The following is the introduction of HTTP://LOCALHOST:63342/PUBLIC/BOOTSTRAP-3.3.5-DIST/CSS/BOOTSTRAP.MIN.CSS

The difference is whether it is a file starting from the root directory. Note the 404 error caused by the underline/

The above introduces the HTML introduction of the file has no underline the difference, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
