如何將行內塊居中-有解無憂

嗨，我有一個簡單的問題。

好吧，我認為對于知道在做什么的人來說很簡單

我試圖將最后一個瓷磚“瓷磚 5”居中

我對這些東西有點陌生，我只是在玩，看看可以做些什么

謝謝

所有代碼都在這里...................................................... ………………………………………………………………………………………………………………………………………………………………………………

uj5u.com熱心網友回復：

你只需要添加text-align: center;到.Tiles 類。

console.clear();

var $allTiles = $(".js-tile");
var $Tiles = $(".Tiles");

$(".Tiles > .Tile").each(function(i, el) {

  var $tile = $(el);
  var target = $tile.children(".Tile-flyout");

  // get each items flyout height with extra buffer
  var thisHeight = target.children(".Tile-content").outerHeight()   20;

  // Create ne timeline in paused state
  var tl = new TimelineMax({
    paused: true,
    reversed: true //,
    //forward: true // not a valid GSAP property 
  });

  TweenLite.set(target, {
    height: 0,
    autoAlpha: 0,
    display: "none" //,
  });
  // animate stuff
  tl.to(target, 1, {
    delay: 0.6,
    height: thisHeight,
    autoAlpha: 1,
    display: "block",
    ease: Cubic.easeInOut,
    overwrite: "none"
  });
  // store timeline in DOM node
  el.animation = tl;

  // create element event handler
  $(el).on("click", function(event) {

    event.preventDefault();

    var that = this;
    var currentTile = $(this);

    $(".Tiles > .Tile.is-expanded").not(this).each(function(i, element) {
      console.log('reverse?');
      element.animation.reverse();
      currentTile.removeClass("not-expanded");
    });

    $allTiles.not(currentTile).removeClass("is-expanded");
    $allTiles.not(currentTile).removeClass("not-expanded");

    currentTile.toggleClass("is-expanded");

    if (this.animation.reversed()) {
      console.log('1');
      $allTiles.not(currentTile).addClass("not-expanded");

      this.animation.play();
      target.removeClass("reversing");
    } else {
