我有这个flexbox用于垂直居中两行文本.两行文字相距太远.这是我正在谈论的图像:

这是我的代码:

CSS

.vertical-center {
  min-height: 100%;  /* Fallback for vh unit */
  min-height: 100vh; /* You might also want to use
                        'height' property instead.

                        Note that for percentage values of
                        'height' or 'min-height' properties,
                        the 'height' of the parent element
                        should be specified explicitly.

                        In this case the parent of '.vertical-center'
                        is the  element */

  /* Make it a flex container */
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex; 

  /* Align the bootstrap's container vertically */
    -webkit-box-align : center;
  -webkit-align-items : center;
       -moz-box-align : center;
       -ms-flex-align : center;
          align-items : center;

  /* In legacy web browsers such as Firefox 9
     we need to specify the width of the flex container */
  width: 100%;

  /* Also 'margin: 0 auto' doesn't have any effect on flex items in such web browsers
     hence the bootstrap's container won't be aligned to the center anymore.

     Therefore, we should use the following declarations to get it centered again */
         -webkit-box-pack : center;
            -moz-box-pack : center;
            -ms-flex-pack : center;
  -webkit-justify-content : center;
          justify-content : center;

          flex-wrap: wrap;

}

p.white, h1.white, h2.white, h3.white, h4.white, h5.white, h6.white {
    color: white;
}

.flexbox-text {
    margin: -50px, 0px, -50px, 0px;
}

HTML

      
{{mottoText}}
      
{{mottoSubText}}
    

忽略角度两种语法.如何让两行文本更接近？
