HTML How to Make a Website CSS: Cascading Style Sheets Center the Wrapper

<div> in css won't change page

When using the css file, I can get it to alter the anchor elements but not the <div> section. Here is my css code:

a {
    text-decoration:none;
}
#wrapper {
    max-width: 940px;
    margin: 0 auto;
    background: orange;
}

Following is the code in my html worksheet:

     <div id:"wrapper">
        <section>
          <ul>
        <li>
          <a href="img/numbers-01.jpg">
            <img src="img/numbers-01.jpg" alt="">
            <p>Experimentation with color and texture.</p>
          </a>
        </li>
        <li>
          <a href="img/numbers-02.jpg">
                        <img src="img/numbers-02.jpg" alt="">
                        <p>Playing with blending.</p>
                    </a>
                </li>
                <li>
                    <a href="img/numbers-06.jpg">
                        <img src="img/numbers-06.jpg" alt="">
                        <p>Write image description here.</p>
                    </a>
                </li>
                <li>
                    <a href="img/numbers-09.jpg">
                        <img src="img/numbers-09.jpg" alt="">
                        <p>Write image description here.</p>
                    </a>
                </li>
                <li>
                    <a href="img/numbers-12.jpg">
                        <img src="img/numbers-12.jpg" alt="">
                        <p>Write image description here.</p>
                    </a>
                </li>
            </ul>
        </section>      
        <footer>
            <a href="http://www.twitter.com"><img src="img/twitter-wrap.png" alt="Twitter Logo"></a>
            <a href="http://www.facebook.com"><img src="img/facebook-wrap.png" alt="Facebook Logo"></a>
            <p>&copy; 2015 Logan Bayless.</p>
        </footer>
      </div>

As other people have mentioned, for some reason the # wasn't included when I copied and pasted, but my code does have a # before wrapper on my css sheet.

In your html, you have

<div id:"wrapper"></div>

this should be

<div id="wrapper"></div>

Hi Wesley. Whatever you typed after "have" and after "be" didn't display on my browser.

Thank you much!

I fixed the formatting for him Logan, so take a look again. And I agree with Wesley, your html is not quite right if you have the : in there.

there we go.... not used to Markdown

Thanks for helping Kevin!
