<div class="btn"><input type="submit" class="wpcf7-form-control wpcf7-submit" value="Send"><img class="ajax-loader" src="http://5unit.com/test/wp-content/plugins/contact-form-7/images/ajax-loader.gif" alt="Sending ..." style="visibility: hidden;">
          </div>
<p></p></div>

The CSS

.contact-box .box .bd {
  padding: 28px 0;
}

.clearfix::after {
  clear: both;
  content: ".";
  display: block;
  height: 0;
  line-height: 0;
  visibility: hidden;
}

.contact-box .box .bd ul li {
  float: left;
  padding-bottom: 2px;
  padding-left: 43px;
  width: 580px;
}

.contact-box .box .bd ul li label {
  display: block;
  font-size: 18px;
  height: 55px;
  line-height: 55px;
}

You can see only first li centered and others and floated left well

Can someone please help me to fix this strange error

Found a solution it happened because WordPress original css had some css effect for this but it's not directly effect somehow when i remove this css it worked

.entry-content h1,
.entry-summary h1,
.comment-content h1,
.textwidget h1 {
    font-size: 28px;
    font-size: 1.75rem;
    line-height: 1.25;
    margin-top: 2em;
    margin-bottom: 1em;
}

Answer 1

I looked at your test site and I see the problem.

The reason is that the element before it (.box .hd. h3) has a large margin-bottom, and the floated element is pushing against that.

Ideally, override that margin-bottom and it will allow the float to work properly.

Alternatively, you can add a "clear:both;" to the first li in your ul.
