Sydney V. 1.33 Custom css in Apperance => Editor do not cause any change

Some custom css entries in Apperance => Editor worked great in Sydney V. 1.22. But in my new project with V 1.33, it does not cause any change.

Two examples:

/* special color menu frontpage */
.mainnavfp ul li a {
color: #FFFFFF !important;


/* special color menu background not mor than 1024 px */
@media only screen and (max-width: 1024px) {
.site-header {
background-color: #ffffff;

Has someone an explanation?


There an incorrect code, please try this instead:

#mainnav ul li a {
    color: red;

.site-header {
    background-color: #FFFFFF;

If its still not working, please share your site URL here, so I can check it for further.


I think it is correct. ‘mainnavfp’ only controls the frontpage. On my old website, made with Sydney V. 1.22, it works. The navigation color is white on the frontpages, black at the other pages.

Hi, could you please to share the URL of your site here?
