【问题描述】：

好吧，最奇怪的事情发生了，我将导航栏与容器分开，现在应该没有空间，我尝试了所有设置 div 边距和填充的方法，我希望它干净而不必使用负边距，非常感谢任何帮助。

CSS

#navbar /* navbar container */
{
    background-color:#999;
    border-bottom:solid 3px #333;
    margin:0px;
}
#navbar ul /* unordered lists withinin navbar container */
{
    width:1000px;
    text-align:center;
    margin-top:0px;
    margin-bottom:0px;
    list-style:none;
    margin-left:auto;
    margin-right:auto;
    padding:0px;
    font-family:"Times New Roman", Times, serif;
    font-size:16px;
    color:#9900FF;

}

#navbar li /* list items within navbar container */
{
    padding-left:20px;
    padding-right:20px;
    display:inline;
    border-right:solid 2px #33FFFF;
    border-left:solid 2px #33FFFF;
}

CSS #2

body /* this is to set the body element, but mostly used for removing margins. */
{
    margin:0px;
    background-color:#666666;
}

#container /* this is our overall content container. */
{
    width:1000px;
    margin-right:auto;
    margin-left:auto;
    background-color:#CCCCCC;
    border-left:groove 5px #444;
    border-right:groove 5px #444;
    border-bottom:groove 5px #444;
}

.logo img /* this is logo on the right side. */
{
    height:100px;
    width:200px;
    float:left;

}

#header1 /* This is the header directly between the logos */
{
    height:96px;
    width:592px;
    font-family:Georgia, "Times New Roman", Times, serif;
    font-size:48px;
    float:left;
    text-align:center;
    alignment-baseline:middle;
    border-left:dashed 4px #00F;
    border-right:dashed 4px #00F;
    border-bottom:dashed 4px #00F;
}

【问题讨论】：

这可能会有所帮助；如果您在容器或徽标周围放置边框；空间消失了。

【解决方案1】：

这很简单。你需要一个像“reset.css”这样的东西......它将所有默认的css设置为它应该是......但现在这将是一个简单的修复：

*
{
   margin:  0;
   padding: 0;
}

【解决方案2】：

将此添加到您的 CSS 中，您应该没问题：

#p1 p {
    margin:0;
}

jsFiddle example。 p1 div 中段落标签的默认边距是原因。

非常感谢！不知道今天我的思绪在哪里，没有意识到我还没有尝试过。

我已更新您的代码，请检查：-

    </div><!-- End of p1 -->
        </div><!-- End of container -->
    </body>
    </html>

CSS

body /* this is to set the body element, but mostly used for removing margins. */
{
    margin:0px;
    padding:0px;
    background-color:#666666;
}

#navbar /* navbar container */
{
    background-color:#999;
    border-bottom:solid 3px #333;
    margin:0px;
}
#navbar ul /* unordered lists withinin navbar container */
{
    width:1000px;
    text-align:center;
    margin-top:0px;
    margin-bottom:0px;
    list-style:none;
    margin-left:auto;
    margin-right:auto;
    padding:0px;
    font-family:"Times New Roman", Times, serif;
    font-size:16px;
    color:#9900FF;

}

#navbar li /* list items within navbar container */
{
    padding-left:20px;
    padding-right:20px;
    display:inline;
    border-right:solid 2px #33FFFF;
    border-left:solid 2px #33FFFF;
}

#container /* this is our overall content container. */
{
    width:1000px;
    margin:auto;
    background-color:#CCCCCC;
    border-left:groove 5px #444;
    border-right:groove 5px #444;
    border-bottom:groove 5px #444;
}

.logo img /* this is logo on the right side. */
{
    height:100px;
    width:200px;
    float:left;

}

#header1 /* This is the header directly between the logos */
{
    height:96px;
    width:592px;
    font-family:Georgia, "Times New Roman", Times, serif;
    font-size:48px;
    float:left;
    text-align:center;
    alignment-baseline:middle;
    border-left:dashed 4px #00F;
    border-right:dashed 4px #00F;
    border-bottom:dashed 4px #00F;
}

我添加了边距填充：0；在您的 CSS 中，您可以使用 reset.css 以便保存默认的额外边距填充......
