CSS：x轴上的固定位置，但不是y？

问题描述：

有没有办法只在x轴上固定位置？

Is there a way to fix a position on the x-axis only? So when a user scrolls up, the div tag will scroll up with it, but not side to side?

答

它是一个简单的技术使用脚本。您也可以查看演示。

Its a simple technique using the script also. You can check a demo here too.

JQuery

$(window).scroll(function(){
    $('#header').css({
        'left': $(this).scrollLeft() + 15 
         //Why this 15, because in the CSS, we have set left 15, so as we scroll, we would want this to remain at 15px left
    });
});

CSS

#header {
    top: 15px;
    left: 15px;
    position: absolute;
}

如所注释的，使脚本支持css中的更改，而不必在脚本中重新编码。您可以使用以下命令。

As commented, to make the script support the changes in the css without having to recode them in the script. You can use the following.

var leftOffset = parseInt($("#header").css('left')); //Grab the left position left first
$(window).scroll(function(){
    $('#header').css({
        'left': $(this).scrollLeft() + leftOffset //Use it later
    });
});
