학교 프로젝트의 Dreamweaver 템플릿에서 탐색을 위해 CSS 스프라이트를 사용하려고하는데 이미지가 표시되지 않습니다. 지금 코드가 있습니다. 지금은 홈 버튼. 각 버튼마다 개별 스프라이트를 만들었습니다. HTML :탐색을위한 CSS 스프라이트가 작동하지 않습니다.

<p>Be aware that the CSS for these layouts is heavily commented. If you do most of your work in Design view, have a peek at the code to get tips on working with the CSS for the fixed layouts. You can remove these comments before you launch your site.

/* ~~ These are the columns for the layout. ~~
1) Padding is only placed on the top and/or bottom of the divs. The elements within these divs have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.
2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a div set to float right). Many times, padding can be used instead. For divs where this rule must be broken, you should add a "display:inline" declaration to the div's rule to tame a bug where some versions of Internet Explorer double the margin.
3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar divs could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.
4) If you prefer your nav on the right instead of the left, simply float these columns the opposite direction (all right instead of all left) and they'll render in reverse order. There's no need to move the divs around in the HTML source.

이 스프라이트로 무엇을 얻으려고합니까? 이미지가 어떻게 보이는지 알 수 없습니다. 수평 또는 수직 이동입니까? 이미지 스왑 (스프라이트가 아님)입니까? 스프라이트는 동일한 이미지가있는 버튼 위에 각 마우스로 배경 위치를 변경해야합니다. 스프라이트 이미지에 대한 링크는 프로세스를 돕는다. –
