thumbnails

问题 I have a website on which there is a "shop" page. Each product has a thumbnail assigned to it. I set a custom thumbnail size with this code: if ( function_exists( 'add_image_size' ) ) { add_image_size( 'products', 150, 84, true ); } Cropping works fine, but when the image is too tall WordPress crops it to the "height" parameter and the final result is a thumbnail too narrow to look good. Is there a way to make WordPress select a part of an image (150x84 px fragment) and use it as a thumbnail

问题 I trying to overlay a play icon on top of thumbnail with css, but not successful. <ul class="thumb-grid"> <li class="play-icon"><img src="image.url"/></li> </ul> You can see the icon when hovering but can't get the icon to go on top of the thumbnail. Does anyone know how? Here is the Fiddle 回答1: Use a pseudo element and change the position style. To preserve your hovering effect you can attach the :hover selector to the list item and target the img inside: html, body { margin: 0; padding: 0;

Vimeo seem to want me to make a HTTP request, and extract the thumbnail URL from the XML they return - what? Who's got time for that?!!! Plus, I'd have to store these URLs too, I can't get them
