html - Which is the correct way to horizontally center this Bootstrap form in MVC? -


when want center div inside div, re-read this post. works. doesn't , million years away expert in css.

here how form constructed:

<h2 class="no-margin-top">revisiones administrativas</h2>    @using (html.beginform())     {         @html.antiforgerytoken()          <div class="form-horizontal">             <hr />

note: layout page doesn't have other divs. deleted them. piece of code rendered alone between html body tags.

can help??

thank you!!

edit

as requested 1 member, here shorter snippet of rendered html

wrap content want centered inside .text-center (you can apply .container). additionally, in case, need:

.text-center select {   margin: 0 auto; } 

that's all. example:

body {    padding-top: 50px;    padding-bottom: 20px;  }      /* set padding keep content hitting edges */    .body-content {    padding-left: 15px;    padding-right: 15px;  }      /* override default bootstrap behavior horizontal description lists      truncate terms long fit in left column   */    .dl-horizontal dt {    white-space: normal;  }      /* set width on form input elements since they're 100% wide default */    input,  select,  textarea {    max-width: 280px;  }    .index-parent-div {    position: absolute;    top: 50%;    margin-top: -200px;    /* half of #content height*/    left: 0;    width: 100%;  }    .index-inner-div {    width: 50%;    margin-left: auto;    margin-right: auto;    height: 395px;  }    .width-100 {    width: 100%;  }    .no-margin-top {    margin-top: 0px;  }    .text-center select {    margin: 0 auto;  }
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />      <div class="container text-center">  <h2 class="no-margin-top">revisiones administrativas</h2>  <form action="/" method="post"><input name="__requestverificationtoken" type="hidden" value="unfimxtwxx4cz4baoodnvnwajrndatr9kxcpyrjgonejyn-xgfjybke088ya3r39smxlneapagu_bkzv2wbnvc3ifiprdrtzegrv_ebojas1" />    <div class="form-horizontal">      <hr />        <div class="form-group">        <label class="control-label col-md-2" for="tipovisitante">tipo de visitante: </label>        <div class="col-md-10">          <select name="tipovisitante" id="tipovisitante" class="form-control">          <option value="descripci&#243;n 1">                                      descripci&#243;n 1                                  </option>                                  <option value="descripci&#243;n 2">                                      descripci&#243;n 2                                  </option>                          </select>          <span class="field-validation-valid text-danger" data-valmsg-for="tipovisitante" data-valmsg-replace="true"></span>        </div>      </div>        <div class="form-group">        <div class="col-md-offset-2 col-md-10">          <input type="submit" value="create" class="btn btn-default" />        </div>      </div>    </div>  </form>  </div>


alternatively, if want center <form> element, easiest way in bootstrap make use of grid system:

<div class="container">   <div class="row">     <div class="col-lg-6 col-lg-offset-3 col-md-8 col-md-offset-2 col-sm-10 col-sm-offset-1 col-xs-12 col-offset-xs-0">        <form>form here...</form>     </div>   </div> </div> 

example:

body {    padding-top: 50px;    padding-bottom: 20px;  }    .dl-horizontal dt {    white-space: normal;  }    input,  select,  textarea {    max-width: 280px;  }    .width-100 {    width: 100%;  }    .no-margin-top {    margin-top: 0px;  }    .text-center select {    margin: 0 auto;  }  @media (min-width: 768px) {  form .form-horizontal .control-label {      text-align: center;      background-color: #f5f5f5;      line-height: 32px;      height: 34px;      padding: 0 15px;      border-radius: 4px;      border: 1px solid #eee;      width: 100%;    }  }  input[type="submit"] {    width: 280px;    max-width: 280px;  }
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />      <div class="container">    <div class="row text-center">      <div class="col-lg-6 col-lg-offset-3 col-md-8 col-md-offset-2 col-sm-offset-1 col-offset-xs-0 col-xs-12 col-sm-10">        <h2 class="no-margin-top">revisiones administrativas</h2>        <form action="/" method="post"><input name="__requestverificationtoken" type="hidden" value="unfimxtwxx4cz4baoodnvnwajrndatr9kxcpyrjgonejyn-xgfjybke088ya3r39smxlneapagu_bkzv2wbnvc3ifiprdrtzegrv_ebojas1" />          <div class="form-horizontal">            <hr />              <div class="form-group">              <div class="col-sm-6 text-center">                <label class="control-label" for="tipovisitante">tipo de visitante: </label>              </div>              <div class="col-sm-6">                <select name="tipovisitante" id="tipovisitante" class="form-control">          <option value="descripci&#243;n 1">                                      descripci&#243;n 1                                  </option>                                  <option value="descripci&#243;n 2">                                      descripci&#243;n 2                                  </option>                          </select>                <span class="field-validation-valid text-danger" data-valmsg-for="tipovisitante" data-valmsg-replace="true"></span>              </div>            </div>              <div class="form-group ">              <div class="col-xs-12 text-center">                <input type="submit" value="create" class="btn btn-default" />              </div>              </div>          </div>        </form>      </div>    </div>  </div>
