使此Javascript倒计时计时器响应

Question

我目前正在为即将上线的网站使用JS倒计时元素的修改版本。我一直在学习大量如何使用flex网格，但是没有用block / inline-block等做很多事情。

目前当倒计时大约945px时，4个内嵌块框保持为4列并最终溢出到屏幕边缘：

我想要的结果是大约945px，4列将并排折叠成2个，文本仍然在他们正确的方框下。我正在乱搞改变chrome中的“inspect”中的代码并意外地成功完成了这一操作，但是4行文本仍然位于带有框的元素下面而不是在适当的位置。这是我想要的结果：

以下是代码：

$(function (){

function countdown() {

var now = new Date();
var eventDate = new Date(2019, 0, 1);
var currentTime = now.getTime();
var evenTime = eventDate.getTime();

var remTime = evenTime - currentTime;

var sec = Math.floor(remTime / 1000);
var min = Math.floor(sec / 60);
var hur = Math.floor(min / 60);
var day = Math.floor(hur / 24);

 hur %= 24;
 min %= 60;
 sec %= 60;

hur = (hur < 10) ? "0" + hur : hur;
min = (min < 10) ? "0" + min : min;
sec = (sec < 10) ? "0" + sec : sec;

$('.seconds').text(sec);
$('.minutes').text(min);
$('.hours').text(hur);
$('.days').text(day);

setTimeout(countdown, 1000);
}

countdown();
});

   </div>

Answer 1

您将.container班级宽度设置为初学者的800px硬值。

.container {
    max-width: 800px;
    width: 90%;
    height: 350px;
    margin:  auto;
    text-align: center
}

进行这种简单的更改将使您的计时器方块在下方开始崩溃。你必须自己做一些更改，但我会研究媒体查询和％的响应式设计。无论何时硬编码800px这样的数字，当你达到较小的尺寸时，你都会遇到问题。

我还会考虑重构你的HTML，以便时间方块和标题在一起。

<div class="time-square">
    <div class="time-square-time">88</div>
    <div class="time-square-title">Days</div>
</div>

您可以通过这种方式更清晰地移动HTML，您将遇到一些与当前结构中的标题匹配的问题

Answer 2

我建议稍微重组您的标记 - 将数字和文本（＆＃39; day＆＃39;，＆＃39; hour＆＃39;等）包装在同一个父级中。这将确保在内容被包装时它们保持在一起。

对于CSS，将width: 800px更改为max-width - 这可确保内容在小于800像素的屏幕上调整大小。

然后，您可以使用CSS Grid来布局框并简化代码。

Answer 3

只要分成div的两个部分，它看起来会很好。

如果我误解了你的问题，请告诉我。

$(function (){

function countdown() {

var now = new Date();
var eventDate = new Date(2019, 0, 1);
var currentTime = now.getTime();
var evenTime = eventDate.getTime();

var remTime = evenTime - currentTime;

var sec = Math.floor(remTime / 1000);
var min = Math.floor(sec / 60);
var hur = Math.floor(min / 60);
var day = Math.floor(hur / 24);

 hur %= 24;
 min %= 60;
 sec %= 60;

hur = (hur < 10) ? "0" + hur : hur;
min = (min < 10) ? "0" + min : min;
sec = (sec < 10) ? "0" + sec : sec;

$('.seconds').text(sec);
$('.minutes').text(min);
$('.hours').text(hur);
$('.days').text(day);

setTimeout(countdown, 1000);

countdown();

Answer 4

您可以使用 CSS媒体查询，如下所示：

@media (max-width: 992px) {
 .container .content > div, .container .title span {
  width: 20%;
 }
}
@media (max-width: 768px) {
 .container .content > div, .container .title span {
  width: 50%;
 }
}
