我已经为我的导航栏使用了一个模板，但我不太确定哪里出了问题。你能更正我的代码吗？

        Creating an error page
        1. Get error code using XMLGetHTTPRequest
        2. Take them to the error page if the website is not found (if the error code is 404)
        3. If the website URL... is fine, execute all of the javascript
        Checking if javascript is enabled or installed
        1. Get the element by id (noscript)
        2. If noscript="true", make an alert warning that tells the user that the website may not function properly if you don't enable their Javascript.
        Creating a slideshow of images
        1. Enable JQuery
        2. Store your slideshow images in variables
        3. Make a variable that will store the amount of time each image will take to cycle (use setInterval)
        4. Make a for function that will slide the images every time the timer reaches a multiple of the variable in number 3.

      /* 
        Make the whole page have a font of Open Sans. Also, add a margin of 40px
        Colour the right column gainsboro and the sidebar white
        Make the blog title bold, underlined and big (Remember to make it stand out)
        Another alternative for the blog title is just an image. In that case, you should:
        Make it repeat horizontally (X) and if the image doesn't have word in it, use figcaption
        Then, make a sidebar by making a border-right that is 1px wide and float it right of the sidebar (Also set the display to relative or fixed)
        , use a template to design the navigation menu (Make sure it's a drop down navigation menu)

希望这不是一个重大错误，因为我为此花了好几个小时!

最佳答案

“关于我”这一项有错误，应该是:

<li class="has-sub"><a href="#"><span>About me</span></a>

和“网页设计技巧”:

<li class="has-sub"><a href="#"><span>Web design tips 'n' tricks</span></a>

子项也一样:“教程”、“名言”和“过去与 future ”
