我有一个固定的位置div:
public String textBetweenWords(String sentence, String firstWord, String secondWord)
{
return sentence.substring(sentence.indexOf(firstWord) + firstWord.length(),
sentence.indexOf(secondWord));
}
String between = textBetweenWords("Hello my dear cousin!", "Hello", "cousin");
println("[" + between + "]")
滚动到页面底部后,我的页脚高度为210px。一旦我滚动到页面的底部,我的固定div重叠到页脚。我怎样才能使固定div不会滚动页脚?
答案 0 :(得分:1)
如果可以javascript
,请参阅代码段,否则您可以:
#fixed{
z-index: 2;
}
your_footer{
position: relative;
z-index: 1;
}
所以至少它不会与页脚重叠,而是在它下面
注意 - 75
是您设置的75px
保证金,如果您看到整个代码段的话,则最好
$(function() {
$(window).scroll(function() {
var foff = $('footer').position().top;
var fh = $('#fixed').height();
var h = $('#fixed').offset().top + fh;
if ( h >= foff) {
$('#fixed').css({
position: "absolute",
top: foff - fh - 75
});
}else{
$('#fixed').css('position','fixed');
}
});
});
* {
margin: 0;
padding: 0;
}
#fixed {
width: 300px;
height: 375px;
margin: 75px;
position: fixed;
right: 0%;
background: red;
}
#content {
width: 70vw;
height: 700px;
margin-left: 15vw;
background: lightgrey;
}
footer {
width: 100vw;
height: 290px;
background: navy;
position: relative;
}
