Need some help at uploading files to web hoster (awardspace)

Hello guys,
I just ripped a landing page with httrack and tried to upload those files to my web hoster, awardspace. The index.html one, pictures and css..
But somehow, as i understood, it didnt catch the css ( i dont really know what that means, im a noob at this haha, but i read and watched many videos about this topic )
Now the landing page looks weird, cuz the normal background picture is at the top, and under it there is only the text written in normal black colour..
Could someone help…
