Adjusting the size of HTML checkboxes for creating PDF documents

Currently facing a dilemma. When it comes to resizing checkboxes in HTML, the common recommendation is to use JavaScript to prompt the browser to adjust the size of the elements.

However, in our scenario, we rely on wkhtmltopdf, a command line tool that utilizes webkit to generate HTML output for PDF conversion, and as far as I know, it does not support the execution of JavaScript.

In this situation, we are in need of a solution to resize numerous checkboxes and radio buttons (to be precise, a considerable amount of them!)

What approach can be taken to achieve this, and if there are multiple methods, what would be considered the best practice?

Answer №1

Even though this thread is quite old, I encountered the same issue and couldn't find a satisfactory solution anywhere. Therefore, I decided to share my find to assist others facing a similar problem. My issue revolved around adjusting the size of checkboxes in a PDF generated by mdpf. The only effective solution turned out to be altering the font-size. You can try the following code:

<input type='checkbox' style='font-size: 20pt;'>

I hope this information proves helpful to someone in need.

Answer №2

Did you experiment with creating a separate print stylesheet to observe its impact on the final display?

@media print { /* include your css code here */ }

Answer №3

Have you attempted using CSS to adjust the size of the elements? It has been tested successfully in Chrome, which is a webkit based browser.

input.big{
  height: 2em;
  width: 2em;
}

input.small{
  height: 0.5em;
  width: 0.5em;    
}

<input type="checkbox" id="small" class="small"/><label for="small">Small</label>
<input type="checkbox" id="big" class="big"/><label for="big">Big</label>

Answer №4

My attempts to change the font size were unsuccessful in altering the output as desired. However, I discovered that the PDF property 'transform' was effective in achieving the desired result. This property allows for the use of decimal points, with a value of 1.5 proving to be most suitable. A value of 2, on the other hand, resulted in the radio-button or checkbox being too large.

$"<input style=\"transform: scale(1.5);\" type=\"checkbox\" id=\"{q.Id}\" data-pdf-form-field=\"true\" name=\"foobar\" {check}>"
