HTML5和CSS如何创建单独的ul和移动 <aside> 向左转

Question

How do I push the image to the side and to the top? Also how do I control each UL LI on their own and not as a general?

First off, you have some syntax errors in your HTML.

1) Several of you anchor tags are not closed. You forgot the / in the closing tags.

2) Your image tag is inside a <ul> , but not inside a <li> . Anything you put in a list tag needs to be a <li> .

Corrected HTML:

<div class="header">
  <h1>Merry Christmas</h1>
  <img src="http://ntt.cc/wp-content/uploads/2009/11/Bell.png" class="bells" />
  <ul id="lil">
    <li><a href="">Aboutus</a></li>
    <li><a href="">Christmas</a></li>
    <li><a href="">Snow</a></li>
    <li><a href="">OtherHolidays</a></li>
  </ul>
</div>
<aside id="sideBar">
  <ul>
    <li>What is christmas</li>
    <li>Do I celebrate Christmas</li>
    <li>Is Christmas fun?</li>
    <li>Conclustion</li>
  </ul>
</aside>

There are a lot of options here.. you could use absolute positioning for a quick fix..

img{
    position: absolute;
    top: 10px;
    left: 10px;
}

You could use media queries to make it different sizes deending on the size of the screen..

/* Large desktop */
@media (min-width: 1200px) {
    img{
        width:30px;
        height: 30px;
    }
}

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) {
    img{
        width:25px;
        height: 25px;
    }
}

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Or any number of other tricks, but ideally, you should use some kind of scaffolding. Something like Bootstrap makes this kind of thing much easier to manage.

If you're interested in Bootstrap, these 3 links should help get you going very quickly. Google is now checking for mobile compatibility, so using BS will also improve your search ranking.

• This one is a single page blank bootstrap template that pulls the BS files from a CDN so you can get started without downloading anything. Just copy this into a blank html document and you're ready to use any of the examples in the next two links.

• This one explains the scaffolding and how to position items on the page. Bootstrap is a responsive framework, meaning it automatically resizes the page for smaller devices.

• And this one explains all the built-in styling tools it comes with. Jumbotron might be useful for this.
