i see in your css:

#top .main_color .input-text, #top .main_color input[type="text"], #top .main_color input[type="input"], #top .main_color input[type="password"], #top .main_color input[type="email"], #top .main_color input[type="number"], #top .main_color input[type="url"], #top .main_color input[type="tel"], #top .main_color input[type="search"], #top .main_color textarea, #top .main_color select {
    border-color: #363636;
    background-color: #111111;
    color: #8c8c8c;
}

and this is in your vip.entertainment.css ( don’t know where this comes from- it is no enfold including css file)
or do you have renamed your child-theme?

change the background-color to your #fff

try to overwrite these rules on taking the contact-form 7 classes:

.wpcf7-form .wpcf7-select, 
.wpcf7-form .wpcf7-text {
	background-color: #fff !important
}

Maybe a plugin can give you this feature.
But you have to make a lot of css instructions to have main etc to be at least semitransparent.

Kriesi itself got a photo theme : flash – looks a bit of that you like to have : Link
but it does not have that brilliant Avia Layout Builder integrated.

so here is an old plugin – but it will do the job: https://wordpress.org/plugins/responsive-full-width-background-slider/

if you like to have shrinking header or fixed header you must have no margin on top !
if you can live with scrolling header : only a few settings are necessary!
you can place your content on left or center with a few css rules.

but: you see there must be some settings to do to have behind content a semi-transparent look and feel.

well – i can not simulate it on ipad and i don’t know where your break-point to mobile view is
but i would get rid of that align center method and try to position it in this way:

.av_secondary_right .sub_menu {
    padding-left: 0;
}

#avia2-menu {
    width: auto !important;
    position: relative !important;
    float: left !important;
    left: 50% !important;
    transform: translateX(-50%);
}

can you try this and have a look to your ipad if it works the way you want

you have clicked on one of those columns. because the visual hover-state of my test-page is in quick css.

you have downloaded the column.php again as in thread here https://kriesi.at/support/topic/make-entire-column-clickable/#post-909911

you have read this carefully: https://webers-testseite.de/edited-enfold-alb-elements/

i think you are using an old demo template
test.kriesi.at does not exist anymore since Kriesi switched to https.

You use Gym demo and the hero 2 is:

it is the background-image on that color-section.

link is now: https://kriesi.at/themes/enfold-gym/files/2016/02/hero-2.jpg

i’m now looking for the code error : why the link_target does not work on my end.

on my Enfold it works: https://webers-testseite.de/weber/clickable-columns/

you see that : https://kriesi.at/support/topic/make-entire-column-clickable/#post-909838

and think of Josues css code:

a.flex_column {
    text-decoration: none !important;
}

i guess i know: it does not make a sense to set for iconbox a link here !

First i edited again links are the same as above.
I added the option to set the link target !

1) on which version of enfold you are with your install ?
2) what is behind that custom-class (iconboxstyle) ? (css code please)

the problem is that josues edited columns.php shortcode is more than 2 Years old

here is one edited new columns.php file of Enfold 4.2.3 on pastebin : columns.php with clickable link

or as direct download: Download

i have inserted on the edited lines some comments !

1) Now download it – and upload it to your child-theme/shortcodes folder
2) insert in functions.php of your child-theme:

add_filter('avia_load_shortcodes', 'avia_include_shortcode_template', 15, 1);
function avia_include_shortcode_template($paths)
{
  $template_url = get_stylesheet_directory();
      array_unshift($paths, $template_url.'/shortcodes/');
  return $paths;
}

3) see how it looks on ALB:
see here in Action ( the red 1/2 column): https://webers-testseite.de/weber/clickable-columns/

update to enfold 4.2.3 this solves my trouble concerning to that topic.

i don’t know how big was the version-difference on your last update – but this could alwas happen when new features are added.
f.e. the hamburger menu changes on 4.0.x to 4.1.x

i always update via ftp. this wastes a bit more time – but it is the safest way.

my contact you can see on my Avatar – leads to my homepage

is it so bad to see a red dot when you know it has no safety nor performance relevance ?
I can live with the fact that the included version lags a bit behind ;)
