Troubleshooting ng-bind-html issue with displaying images loaded using CSS within HTML content

I followed the instructions provided in a related post on the same topic. I used 'ngSanitize' and formatted the HTML content using 'sce.trustAsHtml()', and it rendered correctly when the HTML contained both text and images. However, I encountered an issue when the HTML content had an image loaded using CSS. Here is the HTML content that I am attempting to bind:

<html> <head> <style> body{ padding: 0 0; margin: 0 0; } .img-wrapper{ 
width: 100%; height: 50%; margin: 0 auto; background: url('http://www.fnordware.com/superpng/pnggrad8rgb.png')
 no-repeat center; -webkit-background-size: contain; -moz-background-size: contain; 
-o-background-size: contain; background-size: contain; } </style> </head> <body> <div>
<div class='img-wrapper'></div><div style='font-size: 20px;' >Test the image upload or not 
successfully</div> <div align=center style='font-size: 17px;'>Address goes here</div>
</div> </body></html>

My JavaScript code is as follows:

$scope.content = $sce.trustAsHtml(adTemp.content);

And the HTML code to bind the content is as follows:

<div ng-bind-html="content"> </div>

Answer №1

After some trial and error, I have discovered a solution. When binding HTML with images rendered using CSS background properties, it's crucial to specify the size of the div. Angular tends to ignore image sizes set in external CSS files within style tags. Additionally, it's best practice to avoid nesting the original div within a parent div when setting a background image. Here is the initial HTML code snippet:

<div style="width:500px; height:600px;" ng-bind-html="myHtml"></div>

And here is the modified HTML content that needs to be bound:

<html> <head> <style> body{ padding: 0 0; margin: 0 0; } .img-wrapper{
width: 100%; height: 50%; margin: 0 auto; background: url('http://www.fnordware.com/superpng/pnggrad8rgb.png') no-repeat center; -webkit-background-size: contain; -moz-background-size: contain; -o-background-size: contain; background-size: contain; } </style> </head> <body>
<div class='img-wrapper'></div><div style='font-size: 20px;'>Test the image upload or not successfully</div> <div align=center style='font-size: 17px;'>Address goes here</div> </body></html>
