I need to change the css of the home page only, I have googled and a lot of the suggestions were to add the page id as part of the css selector. But when I try it, it doesn't seem to work? I want to change the class ".contentclass" and the pages id is "599" so here's what I've tried:
.post-id-599 .contentclass {}
.page-id-599 .contentclass {}
.body-id-599 .contentclass {}
none of them seems to be working...
Link to the webpage I'm working on: Link
Try using the right click "inspect element" or equivalent for your browser.
When I look at your site I see something like this
<body class="page page-id-624 woocommerce-cart woocommerce-page boxed varukorg" style="">
So for example for this page: http://witdesign.se/wp/varukorg you would use
body.post-id-624 .contentclass {}
Any styles within the braces will be applicable to the pages with a body class of post-id-668
To be sure, you will need to check what renders in your browser using an inspector.
If your theme uses body_class() in the body tag, you will have a specific css class for the front page (.home), which you could use in the stylesheet;
Example (might be different for your theme):
.home #content .entry { color: #123edf; }
to overwerite the genral stylesheet style.css, you could use a conditional statement in header.php to link a specific stylesheet for the front page:
Example:
<?php if( is_home() ) { ?>
<link rel="stylesheet" type="text/css" media="all" href="<?php echo get_stylesheet_directory_uri(); ?>/front-style.css" />
<?php } ?>
the code needs to be after the link to the general stylesheet.
(instead of is_home() you might need to use is_front_page() )
Check: Conditional_Tags and get_stylesheet_directory_uri
--
alternative, to load a different stylesheet instead of the general stylesheet, use the conditional statement with an else:
(this code would replace the link of the general stylesheet)
Example:
<?php if( is_home() ) { ?>
<link rel="stylesheet" type="text/css" media="all" href="<?php echo get_stylesheet_directory_uri(); ?>/front-style.css" />
<?php } else { ?>
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<?php } ?>
body.home in your CSS file instead of .home just in case the theme author has used a home class anywhere else.
