Filter applied to css selector

comment:1 @nacin3 years ago

Why might modifying this selector be necessary?

comment:2 @Horttcore3 years ago

With the filter you could set it to any other element i.e. html which could be better for the theme.

Here is a sample code:

body {
   margin: auto;
   width: 965px;
}

With the current selector just a part of the site will have the custom background.
The background should be applied to the highest element in the DOM by default and that would be html.

We could add this filter or just change the selector to the html element.

What do you prefer?

Having a filter in a custom callback doesn't sound like a good plan, since we cannot ensure that plugin/theme authors are including the filter in a custom callback too.

Replying to ocean90:

Having a filter in a custom callback doesn't sound like a good plan, since we cannot ensure that plugin/theme authors are including the filter in a custom callback too.

Right, when the custom-background theme support is added, the theme may supply a customwp-head-callback callback which would not be required to the proposed filter. However, if there was a filter, then themes would have much less cause to have to override wp-head-callback's default callback of _custom_background_cb to begin with. I would imagine that providing a custom callback for wp-head-callback is usually due to a different selector being needed.

As an alternative to providing a filter, there could be a new default element-selector property of the custom-background theme support. A custom theme callback would still need to honor element-selector, but they also have to do this already for background repeats, positions, and attachments. See 21627.diff.

+1 for 21627.diff.

comment:11 follow-up: @SergeyBiryukov11 months ago

The selector also appears in customize-preview.js. Should it be updated there as well?

Sorry, ignore .3

21627.4.diff builds on @westonruter's patch to include:

  • customize-preview.js
  • take theme authors preference in get_body_class()

customize-preview.js requires the element be selectable without the class, so I've split the element and the selector into two options applied to the theme-support array.

Thanks, but accessing settings from the parent frame via window.parent._wpCustomizeSettings isn't going to make it into Core. So either you need to use postMessage passing, or export the settings directly into the preview instead via WP_Customize_Manager::customize_preview_settings().

Thanks for the feedback, I've updated in 21627.5.diff to use the correct method.

Whilst this code allows theme authors to customise the element and the class, it still enforces the overloaded element.classname selector, is it worth including a third setting and defaulting to the overloaded selector?
