How to arrange Bootstrap alerts into two columns?-CodePudding

I have a very simple to-do like page where I can enter members and remove them or mark them as done. The members are Bootstrap alerts, so far so good.

My problem is, that the alert/members are too wide and should be in two or three columns, to be able to view more of them on the screen.

This is where I get stuck, because the grid system doesn't want it. I don't know what am I missing...

Can someone please help me, how to rearrange the member list into two or three columns?

I tried with the columns with the team1 button.

This is the JSFiddle URL for it: https://jsfiddle.net/voriand/zsfo65wb/

$(document).ready(function() {
  $('.btn-addmember').click(function() {
    if ($('#text').val().length != 0) {
      var x = $('#memberlist').html();
      var y =
        `<div >
        <a href="#"  data-dismiss="alert" aria-label="close">×</a>
                            `   $('#text').val()   `</div>`;
      $('#memberlist').html(y   x);
      $('#text').val("");
    } else alert("Please, enter the name of the member");
  });
  
  //Adding members of team1
  $('.btn-team1').click(function() {
    if ($('#team1').val().length != 0) {
      var members = $('#team1').val().split('\n');

      for (var i = 0; i < members.length; i  ) {
        var x = $('#memberlist').html();
        var y =
          `<div ><div >
                                        <a href="#"  data-dismiss="alert" aria-label="close">×</a>
                                        <b>`   members[i]   `</b></div></div>`;
        if (members[i].trim().length > 0) {
          $('#memberlist').html(y   x);
        }
      }
    }
  });

  //Adding members of team2
  $('.btn-team2').click(function() {
    if ($('#team2').val().length != 0) {
      var members = $('#team2').val().split('\n');

      for (var i = 0; i < members.length; i  ) {
        var x = $('.container').html();
        var y =
          `<div >
                                        <a href="#"  data-dismiss="alert" aria-label="close">×</a>
                                        <b>`   members[i]   `</b></div>`;
        if (members[i].trim().length > 0) {
          $('.container').html(y   x);
        }
      }
    }
  });
  // When Member is clicked
  $(document).on('click', '.alert', function() {
    if ($(this).css('text-decoration-line') == "none") {
      $(this).css('text-decoration-line', 'line-through');
      $(this).css('background-color', '#dddddd');
      $(this).css('border-color', '#dddddd');
    } else {
      $(this).css('text-decoration-line', 'none');
      $(this).css('background-color', '#dff0d8');
      $(this).css('border-color', '#d6e9c6');
    }
  });

clarify HTML:
- use CSS margin property instead of <br>
- use the text-center class instead of center tag
- place footer at the end of HTML in the <footer> tag
- use .container instead of .container-fluid and empty columns
- use hierarchy .form-inline > .input-group > .input-group-btn to organize inputs and buttons as inline form
CSS:
- I've removed some CSS instructions and restored original behavior of Bootstrap's container. I recommend to use Bootstrap 4 or 5 with flex-boxes to achieve more flexible possibilities.
- I've added styles for form-inline block to improve its layout on he narrow screen.
Redo JS:
- wrap the alert HTML code in a separate function addMember
- add one more function for adding of teams by the textarea's id
- simplify click code for the buttons with a help of these two functions
- use .toggleClass() instead of .css() to change the alerts appearance on click
- use .append() to add new alert at the end of the list
Make columns:
- Wrap alerts in the column block to place several alerts in a line.
- Add two classes col-xs-6 col-sm-4 to organize alerts in 2 columns on mobile and in 3 columns on the wide screen.
- Now Bootstrap's dismissible alerts are not enough, because we have to remove the column block too. So we can remove the alert-dismissible class and the data-dismissattribute. I've added alternative member closing code by jQuery too.

CodePudding user response：

However much your layout can be improved, other answers here have already did that for you. But if you're looking to just break the alert into 3 columns without having to change your entire code, just add the class col-sm-4 (which will produce 3 columns on the viewport from the small screen size) on your JS line where you assign the value to y. So that particular statement now becomes:

var y = "<div class='alert alert-success alert-dismissible fade in'><a href='#' class='close' data-dismiss='alert' aria-label='close'>×</a>" $('#text').val() "</div>";
