hi there this might be a silly question but im learning as i go.
i looked at a dropdown menu which contains a html page a java script .js page and a .css page.
if i wanted to have an index page using the dropdown menu i would have my .index .js and . css file.
now my site already has a .css file so can i just combine the two .css files and save them as one as the one attached to the dropdown menu is only associated with the dropdown menu.
ive done this and it seems to be working ok.
i am only having the dropdown on the index page.

hope ive put that right :-/

Nice progress, . Combining the dropdown CSS into the main stylesheet is a common and sensible approach: it reduces the number of requests and centralizes maintenance, which echoes 's point about fewer file calls. 's suggestion to include a second stylesheet only on the index page is also valid — loading a page-specific stylesheet can save bytes on other pages if the dropdown is only used once.

Important things to watch when merging: order and specificity. Global/base rules belong first, component rules (the dropdown) after. If layout differences show up elsewhere, the usual causes are selector collisions or cascade order. Scoping component styles so they only apply where the widget exists prevents accidental overrides. For example:

<!-- wrapper added around dropdown -->
<div class="dropdown-widget">
  <!-- dropdown markup -->
</div>

.dropdown-widget .menu { /* dropdown styles */ }
.dropdown-widget .menu li { /* ... */ }

A safe workflow: keep backups of the originals, merge into a working file, and test the index plus other pages. Use the browser DevTools Network panel to confirm the stylesheet is being requested and cached, and the Elements/Computed panels to see which rules are taking effect. Look for broad selectors like ul, .menu, or styles targeting tags that could be too general; rename or increase selector specificity rather than resorting to !important.

Performance note for later readers: the old advice to always concatenate came from HTTP/1.1 limits. With HTTP/2/3 multiplexing, splitting assets by feature or loading page-specific CSS is often fine. For a small site a single minified, gzipped stylesheet is simplest. For larger sites, consider critical (above-the-fold) CSS plus lazy-loading noncritical components. Either approach works — the key is preserving correct order, scoping component styles, and testing across pages and browsers.

you would be better off making 2 links to external css files on the index page:

<link href="mainstyle.css" rel="stylesheet" type="text/css" />
<link href="substyle.css" rel="stylesheet" type="text/css" />

And only have a link to the mainstyle on the other pages. This way your site will load quicker, as it wont have to load so much information on the other pages
