非画布菜单和固定定位标题

Question

我正在创建一个非常基本的画布菜单,一切都工作出色,但这一件小事我无法解决!

1. 访问www.loaistudio.com并将窗口重新调整为1000px以下.
2. 向下滚动一下,然后单击标题左上角的"菜单"按钮.

为什么绝望？它实际上并不绝望,但它只是移动到页面的顶部!这是为什么？如何修复它并将其保持在视图区域的顶部...

这是HTML

            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

JavaScript的:

$(document).ready(function() {

    //Prevent clicking on .active links
    'use strict'; $('.active').click(function(a) {
        a.preventDefault();
    });

    //Smart Navigation
    $(".secondHeader-menuButton").on('touchstart click',  function(e) {
        e.preventDefault();
        $("#page").toggleClass("pageOpen");
        $("#headerWrapper").toggleClass("headerOpen");
        $(this).toggleClass("secondHeader-menuButton-active");
    });

    $('.content').on('touchstart click', function() {
        $("#page").removeClass("pageOpen");
        $('#headerWrapper').removeClass('headerOpen');
        $('.secondHeader-menuButton').removeClass("secondHeader-menuButton-active");
    });

}); 

Answer 1

尝试将#headerWrapper转换更改为:

-moz-transition: -moz-transform 0.2s ease-out;
-o-transition: -o-transform 0.2s ease-out;
-webkit-transition: -webkit-transform 0.2s ease-out;
transition: transform 0.2s ease-out

至于翻译后标题变为"不固定":这似乎是Webkit中的一个已知错误.

您可以通过以下方式修复:

1)在#page之外移动#secondHeader:

    <body>
      <header id="headerWrapper"></header>
      <div id="secondHeader"></div>
      <div id="page"></div>
    </body>

2)添加一个新的CSS类:

    #page.pageOpen, #secondHeader.pageOpen {
        -webkit-transform: translate(200px, 0px);
        -moz-transform: translate(200px, 0px);
        -o-transform: translate(200px, 0px);
        -ms-transform: translate(200px, 0px);
        transform: translate(200px, 0px);  
    }

3)向#secondHeader添加转换

    #secondHeader {
      -moz-transition: -moz-transform 0.2s ease-out;
      -o-transition: -o-transform 0.2s ease-out;
      -webkit-transition: -webkit-transform 0.2s ease-out;
      transition: transform 0.2s ease-out
    }

4)通过Javascript切换这个类:

$(".secondHeader-menuButton").on('touchstart click',  function(e) {
    e.preventDefault();
    $("#page, #secondHeader").toggleClass("pageOpen");
    $("#headerWrapper").toggleClass("headerOpen");
    $(this).toggleClass("secondHeader-menuButton-active");
});

$('.content').on('touchstart click', function() {
    $("#page, #secondHeader").removeClass("pageOpen");
    $('#headerWrapper').removeClass('headerOpen');
    $('.secondHeader-menuButton').removeClass("secondHeader-menuButton-active");
});
