could of check out? great little bit of help!

thanks, yngvar

setting height 100% using css work, you'll have revise html structure in order maintain it's flow when window resized.

otherwise, can try following code snippets:

js:

var $imagewrapper = $('#background-image'),     $contentspacer = $('section#wrapper > header'),      // buffer value, adjust rest of content aligned     buffer = 200;  // set div height on pageload $(document).ready(function() {    var windowheight = $(window).height();     $imagewrapper.height( windowheight );    $contentspacer.height( windowheight ); });  // change div height on window resize $(window).resize(function() {   var $this = $(this),       thisheight = $this.height();    // set height of image container window height   $imagewrapper.height( thisheight );   $contentspacer.height( thisheight - buffer ); });

css:

#background-image {   background-size: cover;    // change minimum height page support   min-height: 600px; }

the rest of code have seems correct, adding these should fix things up. couple of things keep in mind here:

  • the js isn't placing limitation on height being applied here, css still apply if window resized 10px height. designs have minimum height/width before breaking, using min-height on #background-image div might idea.

  • check browser support before implementing, if need support 1 of unsupported browsers, you'll need either write fallback or restructure code in such way degrades gracefully. ie9+, chrome21+ , ff26+ should enough though.

  • looks you're using spacer in main section ensure page content comes in after main slider. structure of page can modified don't have modify 2 element heights. mentioned @ beginning, can use pure css solution if restructure.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
