javascript - 如何将文本对齐到标签的底部？

Question

我在开发的元素中遇到了视觉方面的问题

问题与标签中的文本对齐有关。我无法将文本与标签底部对齐。如果你运行代码片段，你可以检查我的问题。

片段:

jQuery(function() {
Date.prototype.addDays = function(days) {
  var dat = new Date(this.valueOf());
  dat.setDate(dat.getDate() + days);
  return dat;
}
Date.prototype.yyyymmdd = function() {
  var mm = this.getMonth() + 1; // getMonth() is zero-based
  var dd = this.getDate();

  return [this.getFullYear() + "-",
          (mm>9 ? '' : '0')  + mm + "-",
          (dd>9 ? '' : '0')  + dd 
         ].join('');

如果您运行该代码段，请检查标签文本(Chegada、Saída、Quartos、Adultos)是否与其他文本相关。

有什么办法可以通过css解决这个问题吗？

Answer 1

您可以使用下面给定的 CSS 将文本对齐到标签的底部

display: table-cell;
vertical-align: bottom;

只需将您的 CSS 替换为 label，如下所示

label{
  /*display: block;*/
  display: table-cell;
  vertical-align: bottom;
  width: 75px;
  height: 40px;
  text-align: center;
}

请看下面的片段

jQuery(function() {
Date.prototype.addDays = function(days) {
  var dat = new Date(this.valueOf());
  dat.setDate(dat.getDate() + days);
  return dat;
}
Date.prototype.yyyymmdd = function() {
  var mm = this.getMonth() + 1; // getMonth() is zero-based
  var dd = this.getDate();

  return [this.getFullYear() + "-",
          (mm>9 ? '' : '0')  + mm + "-",
          (dd>9 ? '' : '0')  + dd 
         ].join('');
};

var date0 = new Date();
date0 = date0.yyyymmdd();
var date1 = new Date();
date1 = date1.addDays(1);
date1 = date1.yyyymmdd();
jQuery("#datepiker_0").datepicker({
      dateFormat: 'yy-mm-dd'
   }).datepicker('setDate', date0)
jQuery("#datepiker_1").datepicker({
      dateFormat: 'yy-mm-dd'
   }).datepicker('setDate', date1)

jQuery("#datepiker_1").focusout(function(){
  
});

jQuery("#num_quartos").focusout(function(){
