html - 页脚与其他内容分开

Question

所以我没有在页脚之前的部分设置边距，但不知何故它是分开的，我似乎无法找出原因。任何想法？谢谢!

html:

<section>
<div class="content"></div>
</section>

<footer>
<div id="footer"></div>
</footer>

和CSS:

.content{
 background-image: linear-gradient(bottom, rgb(135,127,127) 0%, rgb(37,37,35) 69%);
 background-image: -o-linear-gradient(bottom, rgb(135,127,127) 0%, rgb(37,37,35) 69%);
 background-image: -moz-linear-gradient(bottom, rgb(135,127,127) 0%, rgb(37,37,35)        69%);
 background-image: -webkit-linear-gradient(bottom, rgb(135,127,127) 0%, rgb(37,37,35) 69%);
 background-image: -ms-linear-gradient(bottom, rgb(135,127,127) 0%, rgb(37,37,35) 69%);

 background-image: -webkit-gradient(
linear,
left bottom,
left top,
color-stop(0, rgb(135,127,127)),
color-stop(0.69, rgb(37,37,35))

);

 #footer{
  background:url(images/footer.png) left top no-repeat;
  height:450px;
   }

在做任何样式之前尝试应用 CSS Reset:http://meyerweb.com/eric/tools/css/reset/
