As long as the background property fixed value is not supported and might not be supported in the future at all, I have a massive problems to apply the background using CSS background property anyway. I'm building WP custom theme and all images inserted by background property are not visible on iOS devices. Is this normal? I have opened the thread here https://stackoverflow.com/questions/72633738 but no one knows why this is not working. My background is inserted like this: `.services { position: relative; background-image: url(https://exp-theme.local/wp-content/themes/exp-theme/img/brick-wall-mobile.jpg); background-position: right; background-repeat: no-repeat; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; }` Exactly the same story is with .svg icons they are not clickable on iOS devices, I must use .png instead otherwise users are not able to click on them.
