2,233 PointsWhy background-blend-mode does not render in the customizer real time postMessage?
Hello, Does anyone have an idea on why background-blend-mode is not applied in postMessage (real time) when using the WordPress Customizer?
I have an image_control that looks like this
$wp_customize->add_setting(
'parallax_image',
array(
'default' => get_stylesheet_directory_uri() . '/images/big-team.jpg'
'transport' => 'postMessage'
)
);
$wp_customize->add_control(
new WP_Customize_Image_Control(
$wp_customize,
'parallax_image',
array(
'settings' => 'parallax_image', //cta_image_uploader
'section' => 'team_parallax', // cta_section
'label' => __( ‘Photo’ ),
'description' => __( 'Upload an image of your team.', 'namastethemecustomizer' )
)
)
);
My styles are these:
function namaste_style_header() {
<style type ="text/css">
<?php if ( 0 < count( strlen( ( $parallax_image_url = get_theme_mod( 'parallax_image' ) ) ) ) ) { ?>
.meet-our-team-parallax {
background: #232222 url( <?php echo $parallax_image_url; ?> ) no-repeat fixed;
background-position: center top;
background-blend-mode: overlay;
position: relative;
height: 240px;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
line-height: 200%;
color: #fff;
overflow: hidden;
padding-top: 0;
margin-bottom: 0;
}
<?php }
?>
</style>
<?php
}
And the JS to make the postMessage work looks like this:
wp.customize( 'parallax_image', function( value ) {
var styles = {
backgroundPosition: "center top",
position: "relative",
height: "240px",
backgroundRepeatepeat: "no-repeat",
backgroundAttachment: "fixed",
backgroundSize: "cover",
lineHeight: "200%",
color: "#ffffff",
overflow: "hidden",
paddingTop: "0",
marginBottom: "0",
backgroundBlendMode: "overlay"
};
value.bind( function( to ) {
$( '.meet-our-team-parallax ' ).css( 'background', 'url( ' + to + ')' );
$( '.meet-our-team-parallax ' ).css( styles );
} );
});
All the code runs ok, and the results after saving and when refreshing the actual page on the browser are the expected , but the issue is: the background-blend-mode: overlay; would not work within the Customizer when previewing real time.
Many thanks in advance.
