Question

css

I need to check a post for content in it, how can I do this in wp?
Option: add content to a div with display:none and check if there is content, not an option) the page with a list of posts takes a very long time to load

Answer 1

This can also be done with border-radii https://jsfiddle.net/kuwLs2wa/
And with gradients in the background
And with shadows
And substitute a picture (svg?) into the background, as it was done there.
And also via clip-path.

Answer 2

$checkThis = 66;   // сюда id проверяемой записи. Как получить id записи - зависит от места, где вам нужно это всё проверять.
$checkContent = get_the_content($checkThis);
if($checkContent && $checkContent !== ""){
 // Если контент есть - делаем магию
}
