最小化网格CSS的麻烦

时间：2018-06-29 16:51:38

标签： html css

我已经使用HTML和CSS创建了一个网格，如您所见： enter image description here 但是，当我最小化页面时，填充仅在右侧起作用，最终像这样： enter image description here 我希望它最小化并保持在中央，以便可以在移动设备以及较小的屏幕上查看它。

这是HTML的摘录：

<div align="center" style="padding-top: 60px;">
<div class="wrapper" >

    <div class="box-1"><h1><font face="impact">WELCOME PERSON</font></h1>
      </br>
      <p><font face="impact" size="+2">Cupcake ipsum dolor sit. Amet lemon drops apple pie chocolate. Pudding tart gummi bears. Lollipop fruitcake I love cake cookie. Carrot cake I love pie jujubes bear claw tart chocolate bear claw. Ice cream sweet roll gingerbread gingerbread tart chupa chups cake. Pastry apple pie tiramisu jelly beans caramels jelly. Cheesecake tootsie roll icing. Cake donut jelly beans oat cake caramels oat cake sesame snaps. Pastry candy canes I love cake sesame snaps I love.

  </div>
  <div class="box-2" id="one" onClick="one()"><h1><font face="impact" >Number one</font></div>

  <div class="box-3" id="two" onClick="two()"><h1><font face="impact" >Number two</font></div>

  <div class="box-4" id="three" onClick="three()"><h1><font face="impact" >Number three</font></div>

  <div class="box-5" id="four" onClick="four()"><h1><font face="impact" >Number four</font></div>
     </div>

答案 0 :(得分：2)

width和row height应该具有灵活的值，以便能够适应： 例子：

.wrapper {
  display: grid;
  grid-template-columns: 40% 1fr 1fr;
  grid-template-rows: minmax(250px,1fr) minmax(250px,1fr);/* allow the rows to grow */
  grid-template-areas: "box-1 box-2 box-4" "box-1 box-3 box-5";
  width: 1500px;
  max-width:94%;/* 100% should be a max to be seen without overflow, les than 100% will leave some margin on the sides. pickup the value that fits the best  your needs */

}

请参阅：https://developer.mozilla.org/en-US/docs/Web/CSS/minmax

  

minmax() CSS函数定义了一个大于或等于min且小于或等于max的大小范围。 它与CSS网格一起使用。 

// JavaScript Document
var slidesWrapper = $('.cd-hero-slider');

//check if a .cd-hero-slider exists in the DOM
if (slidesWrapper.length > 0) {

  var sliderNav = $('.cd-slider-nav');
  var slidesNumber = slidesWrapper.children('li').length;
  var visibleSlidePosition = 0;
  var autoPlayId;
