Yii2 why do paths with / at the beginning not work?

Question

Yii

Does not work :

style="background-image: url('/images/header/header.jpg')"

Works:

style="background-image: url('images/header/header.jpg')"

File system:

.htaccess:
web

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php [L]

Application Root:

<IfModule mod_rewrite.c>
    Options +FollowSymlinks
    RewriteEngine on
</IfModule>

<IfModule mod_rewrite.c>
    RewriteCond %{REQUEST_URI} ^/.*
    RewriteRule ^(.*)$ web/$1 [L]

    RewriteCond %{REQUEST_URI} !^/web/
    RewriteCond %{REQUEST_FILENAME} !-f [OR]
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^.*$ web/index.php
</IfModule>
