Code and Methods to Make the Entire WordPress Website Turn Gray

To express the deep mourning of people of all ethnic groups across the country for the martyrs and deceased compatriots in the fight against the COVID-19 pandemic, the State Council has decided to hold a national mourning activity on April 4, 2020. During this period, national flags and flags at Chinese embassies and consulates abroad will be flown at half-mast, and public entertainment activities across the country will be suspended. Starting at 10:00 on April 4, people across the country will observe three minutes of silence, while cars, trains, and ships sound their horns, and air defense sirens wail. As website administrators, we can also remove the color from our websites, turning them entirely gray to pay tribute to the heroes and express our condolences. The method to make a WordPress website gray is very simple: click the customizer button on your website. Then, in the Additional CSS section, paste the following code and publish to see the effect. To revert, simply delete the code after graying out.
