Is there a way to make placeholder text automatically adjust its size to fit within the text input element and display its complete content?

Question

Is there a way to make placeholder text automatically adjust its size to fit within the text input element and display its complete content?

I am working on a piece of HTML code that includes a form with a table for traveler information. However, I am having trouble ensuring that the placeholder text remains fully visible at all times.

To give you a visual example, here is what I currently have:

<form>
    <table border="1">
        <tr>
            <td>Traveler's name:</td>
            <td>
                <input type="text" id="travelername" placeholder="Last Name, First Name, Middle Initial"/>
            </td>
        </tr>
        <tr>
            <td>Traveler's E-mail:</td>
            <td>
                <input type="email" id="traveleremail"/>
            </td>
        </tr>
    </table>
</form>

Despite my attempts to adjust the CSS by reducing the font size and altering the width, the placeholder text remains truncated within the input field. Here is an image showing this issue:

If you have any insights or solutions on how to expand/widen the placeholder text area within the input field while keeping the text fully visible, your help would be greatly appreciated!

If you're looking to adjust text width dynamically using jQuery, here's one approach. You can use jQuery to calculate the text width and set it accordingly in CSS. The code snippet below demonstrates how you can achieve this by checking for empty input fields and adjusting font size based on that.

setInterval(function() {
    $('input').each(function(){
        if($(this).val() === ''){
            $(this).css({
                "width":$(this).width()+"px",
                "height":$(this).height()+"px"
            });
            if(parseFloat($(this).css('font-size'))<=14){
                $(this).animate({
                    "font-size":10+"px"
                });
            }
        }
        else {
            $(this).finish().clearQueue().css({
                "font-size":14+"px"
            });
        }
    });
}, 100);

You can adjust the interval time for better performance based on your needs. Feel free to modify the code as required.

To enhance the functionality and reduce manual input dependence, consider this updated solution:

Create CSS styles for input fields and their clones
Loop through input elements, create a clone, and compare widths with font-size adjustments
Remove inline font-size styling upon user input

// Adjust font-size step value
var step = 0.1;

setInterval(function() {
    $('input').each(function() {
        if ($(this).val() === '') {
            $clone = $('<span></span>')
                .appendTo('body')
                .addClass('inputClone')
                .text($(this).attr('placeholder'));
            
            var fontSize = $(this).css('font-size');
            do {
                fontSize = parseFloat($clone.css('font-size')) - step;
                $clone.css({
                    'font-size': fontSize
                });
            } while ($clone.width() > $(this).width());
            
            $(this).css({
                "width": $(this).width() + "px",
                "height": $(this).height() + "px"
            });
            
            $(this).animate({
                'font-size': fontSize
            });
            
            $clone.remove();
        } else {
            $(this)
                .finish()
                .clearQueue()
                .attr('style', function(i, style) {
                    return style.replace(/font-size[^;]+;?/g, '');
                });
        }
    });
}, 100);

Adjust the step value for font-size reduction and customize CSS styles according to your design requirements.
