Align The Form To The Center In Bootstrap 4


Answer :

You need to use the various Bootstrap 4 centering methods...

  • Use text-center for inline elements.
  • Use justify-content-center for flexbox elements (ie; form-inline)

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">     <div id="cover-caption">         <div id="container" class="container">             <div class="row">                 <div class="col-sm-10 offset-sm-1 text-center">                     <h1 class="display-3">Welcome to Bootstrap 4</h1>                     <div class="info-form">                         <form action="" class="form-inline justify-content-center">                             <div class="form-group">                                 <label class="sr-only">Name</label>                                 <input type="text" class="form-control" placeholder="Jane Doe">                             </div>                             <div class="form-group">                                 <label class="sr-only">Email</label>                                 <input type="text" class="form-control" placeholder="jane.doe@example.com">                             </div>                             <button type="submit" class="btn btn-success ">okay, go!</button>                         </form>                     </div>                     <br>                      <a href="#nav-main" class="btn btn-secondary-outline btn-sm" role="button">↓</a>                 </div>             </div>         </div>     </div> </section> 

<div class="d-flex justify-content-center align-items-center container ">      <div class="row ">           <form action="">             <div class="form-group">                 <label for="inputUserName" class="control-label">Enter UserName</label>                 <input type="email" class="form-control" id="inputUserName" aria-labelledby="emailnotification">                 <small id="emailnotification" class="form-text text-muted">Enter Valid Email Id</small>             </div>             <div class="form-group">                 <label for="inputPassword" class="control-label">Enter Password</label>                 <input type="password" class="form-control" id="inputPassword" aria-labelledby="passwordnotification">              </div>         </form>      </div>  </div>

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">   <div class="row justify-content-center align-items-center">     <h1>Form</h1>       </div>   <hr/>   <div class="row justify-content-center align-items-center h-100">     <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">       <form action="">         <div class="form-group">           <select class="form-control">                     <option>Option 1</option>                     <option>Option 2</option>                   </select>         </div>         <div class="form-group">           <input type="text" class="form-control" />         </div>         <div class="form-group text-center">           <div class="form-check-inline">             <label class="form-check-label">     <input type="radio" class="form-check-input" name="optradio">Option 1   </label>           </div>           <div class="form-check-inline">             <label class="form-check-label">     <input type="radio" class="form-check-input" name="optradio">Option 2   </label>           </div>           <div class="form-check-inline">             <label class="form-check-label">     <input type="radio" class="form-check-input" name="optradio" disabled>Option 3   </label>           </div>         </div>         <div class="form-group">           <div class="container">             <div class="row">               <div class="col"><button class="col-6 btn btn-secondary btn-sm float-left">Reset</button></div>               <div class="col"><button class="col-6 btn btn-primary btn-sm float-right">Submit</button></div>             </div>           </div>         </div>        </form>     </div>   </div> </div>

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
