css - DOMPDF page-break-inside:avoid; property is leaving a blank at start of the pdf -


in code trying add external border frame pdf, when so, content of pdf breaks in between , continue in second page. overcome issue used page-break-inside:avoid; property on parent div. resulted in new strange issue, keeping first page blank (without border) , adding whole content second page (with border) of pdf.

no way me understand doing wrong.

i detailing dummy code snippet below -

<style type="text/css"> @page { margin: 0px; } body { margin: 0px; } html { margin: 0px;} .back-img {     background: url('imageurl');     background-position: top left;     background-repeat: no-repeat;     background-size: 100%;     padding-top: 100px;     padding-left: 100px;     padding-right: 100px;     width:100%;     height:100%; } </style> <div style="page-break-inside:avoid;" class="back-img">     <div style="text-align: center;">         <h1>heading text</h1>         <br>         <img src="imgurl" height="100">         <br><br>         text here         <br>         text here.. text here..         <br>         text here         <br><br>         text here         <br><br>         3-4 lines of paragraph here         <br><br>         <img src="imgurl" height="50">         <br>         text here         <br>         text here         <br>         text here     </div> </div>

dompdf version 0.7.0 php version 7.0.18

your appreciated.

this because set width , height of container div 100%. dompdf doesn't best job flowing elements bumping against margins of page. have few options try address issuue:

  1. set height , width of container bit less containing page. easier if know page dimensions in pt , can specify specific lengths container dimensions.
  2. style container fixed-position element. won't affect document flow , apply generated pages. put margins on page , apply negative values border element.

for latter try like:

<style type="text/css"> @page { margin: 100px; } .back-img {   position: fixed;   background: url('imageurl');   background-position: top left;   background-repeat: no-repeat;   background-size: 100%;   top: -50px;   right: -50px;   bottom: -50px   left: -50px; } </style> <div class="back-img"></div> <div style="text-align: center;">...</div>
