Fixed size DIV with CSS (generate PDF with MPDF)

Question

I need a DIV with fixed size in centimeters width:12.5cm; and height:7.5cm;. I can keep these sizes when loading the view, but when I use PHP’s mPDF class, it ignores the height and increases it according to content. I need that regardless of the content, the size is maintained, even if for that the content goes over the edges.

CSS I’m using in DIV:

.container-ficha {
        background-color:#ffffff;
        width:12.5cm;
        height:7.5cm;
        border:1px solid black;
        margin: 0 auto 0 auto;
    }

Answer 1

The solution I found was to add position:fixed; the class .container-ficha. In so doing he obeyed the width and height.

Answer 2

CSS works in the form of cascades, that is, by hierarchies.

try to use the code !important in their properties which must not be overwritten.

example:

 .container-ficha {
            background-color:#ffffff;
            width:12.5cm !important;
            height:7.5cm !important;
            border:1px solid black;
            margin: 0 auto 0 auto;
        }
