Disable resizing of textarea with SimpleMDE

I'm using SimpleMDE as editor on my page. The code is the following:

    <div class="main">
        <div class="container">
            <div class="main_content">
                <div class="row">

                                <div class="padd_box05">
                                    <form method="post" id="task_create_form">
                                        Description:
                                        <div class="padd_box_top1" name="description">
                                            <textarea name="description" class="task_create_textarea">{{ task.description }}</textarea>
                                        </div>

                                    </form>
                                </div>
                            </div>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>

    <script>

        if ($(".task_create_textarea").length) {
            var task_create_textarea_mde = new SimpleMDE({ element : $(".task_create_textarea")[0], spellChecker: false, previewRender: function(plainText, preview) {
                  setTimeout(function() {
                    markjax(plainText, preview);
                  }, 50);
                  return preview.innerHTML;
                } });
        }
    </script>

</body>

CSS classes: 

.main  {
    padding-top: 3em;
}
.row  {
    margin-left: 0;
    margin-right: 0;
}
.wall  {
    flex-basis: 0;
    flex-grow: 3;
    margin-right: 2em;
}
.box_roundbox  {
    border: 0.15em solid #AAAAAA;
    border-radius: 0.5em;
}
.padd_box05  {
    padding: 0.5em;
}
.padd_box_top1  {
    padding-top: 1em;
}

My problem is: when I type really long strings in textarea generated by SimpleMDE, it just enlarges uncontrollably. How to disable horizontal resizing of padd_box_top1? I tried resize: none;, but nothing changed.

Solution

  • Try setting a max-width like this:

     .padd_box_top1 {
     max-width: 40%;
 }

    This will prevent the textarea from enlarging, if you want a min-width as well you can add that too, just add: min-width: 25%; Change the amount of pixels to whatever you like.
