Adjusting Text Size Depending on Width

I recently used an online converter to transform a PDF into HTML. Check out the result here: http://www.example.com/pdf-to-html-converted-file

The conversion did a decent job, but I'm wondering if it's feasible to have the content scale to 100% width for better mobile usability. While resizing the image width is straightforward, I've encountered issues with getting the text to scale proportionately. I've explored font scaling options, but they disrupt the text layout which is crucial. Both the image and text need to resize simultaneously. I've experimented with using "transform: scale(X)" which achieves the desired effect, but it's not ideal since the PDF width can vary. Is there a way to make this scaling dynamic? Any insights would be greatly appreciated.

Answer №1

To adjust the page scale using JavaScript, you can implement the following approach:

var targetPage = document.querySelector('#pf1');

var calculateScaleRatio = function(element){
    return document.body.offsetWidth / element.offsetWidth;
};

targetPage.style.transformOrigin = 'center top';

var applyZoomEffect = function(){
    targetPage.style.transform = 'scale(' + calculateScaleRatio(targetPage) + ')';
}

Ensure to trigger this function on events such as document ready, resize, and orientation change:

document.addEventListener('DOMContentLoaded', () => applyZoomEffect());
window.addEventListener('resize', () => applyZoomEffect());
window.addEventListener('orientationchange', () => applyZoomEffect()); // may not be necessary

Answer №2

One potential solution could involve incorporating the ONRESIZE event within your PDF's container:

<div id="PDFbox" onresize="DoScale();"></div>




 function DoScale(){

 // Retrieve the new dimensions of your container...

 var W=PDFbox.outerWidth;

 var H=PDFbox.outerHeight;  

 // Then, based on your chosen logic, dynamically adjust and scale accordingly...


AnotherID.style.transform='scale(2,2)';
}

I trust that I have grasped your query accurately.
