HTML Structure

Consider a div element with class:wrapper and inside that div element, consider the four div elements with class:btn and within the each btn div element, consider a p tag with text and two span elements with different classes(BorderTopBottom, BorderLeftRight).

<div class="wrapper">
  <div class="btn">
    <p>Button Effect</p>
    <span class="BorderTopBottom"></span>
    <span class="BorderLeftRight"></span>
  </div>
  <div class="btn">
    <p>Button Effect</p>
    <span class="BorderTopBottom"></span>
    <span class="BorderLeftRight"></span>
  </div>
  <div class="btn">
    <p>Button Effect</p>
    <span class="BorderTopBottom"></span>
    <span class="BorderLeftRight"></span>
  </div>
  <div class="btn">
    <p>Button Effect</p>
    <span class="BorderTopBottom"></span>
    <span class="BorderLeftRight"></span>
  </div>
</div>

CSS Structure

  1. Let’s style the wrapper div in such a way that, it should always be at the center of the browser. by setting its position value to absolute, top and left values to 50% and by using translate method of transform property, place the wrapper div exactly in the center of the browser. Set its width to 760px. 
    .wrapper{
        position: absolute;
        top: 50%;
        left: 50%;
        width: 550px;
        transform: translate(-50%,-50%);
}
  2. Style the all btn div element, by setting its width to 170px, margin to 0 10px, padding to 15px 0, background-color to #fff and float them to left and set its position value to relative, so that we can place its child elements(before and after elements) wherever we want. 
    .wrapper .btn{
    width: 170px;
    margin: 0 10px;
    padding: 15px 0;
    text-align: center;
    float: left;
    cursor: pointer;
    background: #fff;
    position: relative;
}
  3. Style the p tag, by setting its color, font-weight and font-size. 
    .btn p{
    color: #2b2f6c;
    font-weight: 900;
    font-size: 14px;
    text-transform: uppercase;
}

    4. As I mentioned above, here I’m going to use before and after pseudo-elements to achieve the four borders(top, bottom, left and right).

    Top and Bottom Border

  4. Style Top and Bottom borders, By setting its position value to absoltue, width to 50px, height to 3px and background color to #fff. and Now align the Top border by setting its top and left property values to -6px and -7px. and Now align the Bottom border by setting its bottom and right property values to -6px and -7px respectively. 
    .BorderTopBottom:before{
    content: "";
    position: absolute;
    width: 50px;
    height: 3px;
    top: -6px;
    left: -7px;
    background: #fff;
    transition: all 0.5s ease;
}

.BorderTopBottom:after{
    content: "";
    position: absolute;
    width: 50px;
    height: 3px;
    bottom: -6px;
    right: -7px;
    background: #fff;
    transition: all 0.5s ease;
}

    5. Left and Right Border

  5. Style Left and Right borders, By setting its position value to absoltue,width to 3px, height to 25px and background color to #fff. and Now align the Left border by setting its top and left property values to -3px and -7px. and Now align the Right border by setting its bottom and right property values to -3px and -7px respectively. 
    .BorderLeftRight:before{
    content: "";
    position: absolute;
    top: -3px;
    left: -7px;
    width: 3px;
    height: 25px;
    background: #fff;
    transition: all 0.5s ease;
}

.BorderLeftRight:after{
    content: "";
    position: absolute;
    bottom: -3px;
    right: -7px;
    width: 3px;
    height: 25px;
    background: #fff;
    transition: all 0.5s ease;
}

    6. Hover effect

  6. Whenever We hover over the btn, the width of the top and bottom borders change from 50px to 184px and the height of the left and right borders change from the 25px to 56px. and set the transition property for smooth animation effect. 
    .btn:hover .BorderTopBottom:before,
.btn:hover .BorderTopBottom:after{
    width: 184px;
    transition: all 0.5s ease;
}

.btn:hover .BorderLeftRight:before,
.btn:hover .BorderLeftRight:after{
    height: 56px;
    transition: all 0.5s ease;
}
