Hey I wasn't able to replicate your css loading issue using most of the code you provided
In general you have the *.htm files/pages with <html> and <body> tags like you have and the link which references the same file (so just copy that part and it should work for all files)
There are possibly 4 issues which might still exist:
1) the css&htm files are not in the same folder, so the file isn't found
2) the browser cached an old version off the css file which was empty -> try cleaning the browser cache
3) you have many errors in your html which might confuse/break the browser
3.1) you have multiple html and body tags in one file, keep it to only <html><head/><body><stuff></body></html> per file
3.2) your list of many links has links inside of links
3.3) your links in the list of many links has a style tag as the href for the inner link, use class="menulinks" instead and then style it in the css with .menulinks{...}
3.4) the open tag of the inner links is not closed before the text content starts (<em>|FAQ</em> and so on )
3.5) in theory the order of the closing of tags is wrong for the inner links (but fixed if you remove the previously mentioned wrong style tag)
you open a->a->style->em and close em->a->a->style so style should be before the 2 closing </a> tags
3.6) in general you should indent everything, makes everything much clearer, also windows notepad isn't really the best in supporting you to write stuff like that
you might want to consider other editors like notepad++ which are free to download and highlght the syntax for you, have autocomplete and help with the indention and closing tags
4) make sure you have saved the changes and that they aren't there yet (try flashy colors like red or something else obvious)
Also it is easier to help when one has access to the code and doesn't have to retype important parts, copy&pasting it into the question would help, but brainly doesn't really support code so it's not nice and brainly might even reformat it a bit
websites like pastebin or for webdevelopment jsfiddle are useful, but really anything would help even if not intended for that purpose, like a viewable google doc link
I suggest you try fixing the issues from above and if it still doesn't work share the code in some (hopefully better) way
Answer:
17 países.
Explicación:
Hay diecisiete países que tienen vehículos aéreos no tripulados armados y donde se ha implementado un sistema de vigilancia con drones. Los drones son excelentes para recopilar grandes cantidades de datos de imágenes. Se puede implementar fácilmente para la vigilancia y mantener la seguridad. Se puede conducir a través de la computadora, no del piloto en él, por lo que el piloto se guarda. Los aspectos negativos de los drones es que tienen tiempos de vuelo cortos y el clima puede afectar fácilmente a los drones. Las operaciones precisas son difíciles y también eliminan futuros trabajos.
