[英]Header Image is fixed position
I am working on a site for someone and I need to add a header image to the top left of the website. 我正在为某人创建一个网站,我需要在该网站的左上方添加标题图片。 But whats happening is the images seems to be in a fixed position so whenever I move the webpage to different resolutions, it seems to stay where it is while everything else moves.
但是发生的是图像似乎处于固定位置,因此每当我将网页移动到不同的分辨率时,其他一切都在移动时,它似乎停留在原处。 On top of that, i need to image to underlap the navigation, but whenever I change the height of the image, it just changes the height of the header itself which moves the navigation farther...
最重要的是,我需要对导航进行图像叠加,但是每当我更改图像的高度时,它都只会更改标题本身的高度,从而使导航更进一步...
The Image I am referring to is in the html <img src="newImage/papaPic.jpg"> with the CSS being #header img{...}
CSS 的CSS
body {
background: url(../newImages/headerBackground.jpg) repeat;
font-family: Arial, Helvetica, sans-serif;
//font-size: 14px;
margin: 0;
padding: 0;
}
#header {
background: url(../images/bg-header.png) repeat-x bottom center;
margin: 0;
text-align: center;
display: block;
}
#header img {
display: block;
margin: 0 auto;
width: 230px;
margin-left:0px;
height:250px;
}
#header ul {
background: url(../images/menu-border.gif) no-repeat bottom left;
margin: 0 auto;
overflow: hidden;
padding: 0 0 0 1px;
width: 970px;
position:relative;
left:5%;
}
#header ul li {
background: url(../images/bg-menu.gif) repeat-x bottom center;
border-top: 2px solid #4f5342;
float: left;
list-style: none;
margin: 0;
padding: 0;
}
HTML 的HTML

Is this what you need? 这是您需要的吗?
body {
background: url(../newImages/headerBackground.jpg) repeat;
font-family: Arial, Helvetica, sans-serif;
//font-size: 14px;
margin: 0;
padding: 0;
}
#header {
background: url(../images/bg-header.png) repeat-x bottom center;
display: block;
margin: 0;
position: relative;
text-align: center;
}
#header img {
display: block;
height:250px;
position: absolute;
width: 230px;
}
#header ul {
background: url(../images/menu-border.gif) no-repeat bottom left;
margin: 0 auto;
overflow: hidden;
padding: 20px 5px 0 5px;
position: relative;
width: 970px;
z-index: 10;
}
#header ul li {
background: url(../images/bg-menu.gif) repeat-x bottom center;
border-top: 2px solid #4f5342;
float: left;
list-style: none;
margin: 0;
padding: 0;
}
The most important changes are the position: absolute
on the img, the position: relative
on the #header and the position: relative
and z-index
on the ul 最重要的更改是
position: absolute
img上的position: absolute
, position: relative
#header上的position: relative
位置和position: relative
ul上的position: relative
和z-index
