Hi there

I am trying to make this code move the pdf to the left. However, when I apply the css, the pdf disappears completely.

<style>
.left {
float: left;
}
</style>
<section class="left">


That is what I am trying to apply. I have closed the section tags as can be seen in the entire code above. You can see the page here: https://if-charts.000webhostapp.com/YSSY/YSSY_arr.html

As you will be able to see, the pdf is in the centre, and there is a large amount of space between it and the left border. As the pdf can be zoomed, I would like to take advantage of the whole space. I need to move it to the left, but I have no idea how to.

If it helps, the entire repo can be found here: https://github.com/IF-Apps/IF-Charts

And you can find the entire file here: https://github.com/IF-Apps/IF-Charts/blob/Blurfix/YSSY/YSSY_arr.html

Thanks in advance.

Answer

Try adding this to the css:

canvas #the-canvas {
 transform: translateX(-20vw);
}

Hope that helps!

EDIT:

Add it into the canvas element, with the id of "the-canvas" in your html

<canvas height="892" width="629" id="the-canvas" style="border:1px solid black; transform: translateX(-20vw);"></canvas>
