html - Why does "overflow: hidden" cause the text to change size and shape? -

-

under following html , css:

here fiddle of below:

/*css*/    .header {    margin: 0px;    padding: 0px;    width: 100%;  }  .headertable {    padding: 0px;    margin: 0px;    width: 100%;    border-spacing: 0px;  }  .headertabletr {    width: 100%;    padding: 0px;    margin: 0px;  }  .logoanimation {    text-decoration: none;    color: black;  }  .logoanimation p {    display: inline-block;    margin: 0px;  }  .logodisapear1 {    overflow: hidden;    width: 0px;    -webkit-transition: 0.2s linear;    -moz-transition: 0.2s linear;    -o-transition: 0.2s linear;    transition: 0.2s linear;  }  .logoanimation:hover .logodisapear1 {    width: 23px;  }  .logoanimation:hover .logodisapear2 {    width: 56px;  }  .logodisapear2 {    overflow: hidden;    width: 0px;    -webkit-transition: 0.4s linear;    -moz-transition: 0.4s linear;    -o-transition: 0.4s linear;    transition: 0.4s linear;    -webkit-transition-delay: 200ms;    -moz-transition-delay: 200ms;    -o-transition-delay: 200ms;    transition-delay: 200ms;  }
<div class="container">    <div class="header">      <table class="headertable">        <tr class="headertabletr">          <td class="headerlogo">            <div class="logoanimation">              <a href="">                <p>                  <</p>                    <p>c</p>                    <p class="logodisapear1">ode</p>                    <p>u</p>                    <p class="logodisapear2">niversity</p>                    <p>/></p>              </a>            </div>          </td>        </tr>      </table>    </div>  </div>

why 'ode' , 'niversity' move , go smaller?

when delete 

overflow: hidden;

it goes normal size, text overlaps?

the scroll bar takes height in <p> element.

add vertical-align: bottom:
