Well, I thought that worked. It's now causing a different problem. I have individual image tiddlers that contain an <img> tag, pointing to an external image and specifying a CSS class. I then have a series of macros that transclude said tiddler within divs that are modified by other CSS classes. Since I wanted the image tiddler to show an image without knowing its file extension, I did the following to make an image fallback:
Example Image Tiddler: <object data="x.jpg" class="basic_image"> <object data="x.png" class="basic_image"> <img src="x.bmp" class="basic_image"> </object> </object> I have the following macros that I use with the image tiddler: \define single_image(target_image) <div class="single_image"> <<basic_image $target_image$>> </div> \end \define basic_image(target_image) <$button message="tm-modal" param="$target_image$" class="button_image"> <div class="image_container"> {{$target_image$}} </div> </$button> \end I use the following CSS styles: .basic_image { min-width: 150px; } html .image_container { background: #444444; border-radius: 5px; padding: 5px; } .button_image{ padding: 0px; margin: 0px; background-color: #444444; border: none; } .single_image { float:right; width: 150px; margin: 5px; } If both of the object tags are pointing to non-existent files but the image tag is pointing to an existent one, this is the result: https://goo.gl/photos/nyvmxDc2zEaX9sov8 However, if one of the object tags is pointing to an existent file, this is the result: https://goo.gl/photos/bUamzuVp4sAkAYpa8 The first situation is the intended result. It looks like the <object> tag isn't inheriting the width of the div with the single_image class, and I'm not sure how to rectify this problem.
