The following CSS gives a red outline to any img having a missing or blank alt attribute:

css

img:not([alt]),
img[alt=''] {
    outline: 8px solid red;
}

If you are using Visual Studio Code, you can install the webhint extension. It will automatically detect the issue and show the details when you hover on the element.
