So I've been working on a site that uses a JavaScript animation for the background of some of the sections. Right now, the section in question is broken down like this:
<section id="intro">
<div class="info">
<div class="container">
<div class="row">
<div class="col-full"><h1>My Name</h1></div>
</div>
<div class="row"><div class="col-1-4 centered line"></div></div>
<div class="row">
<div class="col-full"><h4>Video<span class="cool">s</span> and stuff</h4></div>
</div>
</div>
</div>
<nav id="nav">
<!-- The content between <span> </span> tags will be hidden on mobile version -->
<ul class="clearfix">
<li>Pro<span>file</span></li>
<li>Ski<span>lls</span></li>
<li>Exp<span>erience</span></li>
<li>Edu<span>cation</span></li>
<li>Por<span>tfolio</span></li>
<li>Con<span>tact</span></li>
</ul>
</nav>
</section>
Originally, I wanted to set the background of the entire section using
dataUrl = canvas.toDataURL();
document.getElementById("intro")[0].style.background='url('+dataUrl+')'
but that didn't work, so I ended up going with
dataUrl = canvas.toDataURL();
document.getElementsByClassName("info")[0].style.background='url('+dataUrl+')'
which did. However, the Nav bar scrolls with the page as you move down, and as soon as the script for scrolling it down kicks in, the background reverts to its default blue color.
My first thought was to simply add
document.getElementById("nav")[0].style.background='url('+dataUrl+')'
but that didn't work. I had some success with
document.getElementByClassName("clearfix")[0].style.background='url('+dataUrl+')'
but only the area immediately surrounding the text used the animated background; the rest was still blue.
So I'm not sure if it's some issue with getElementById, or if you can't use style.background with <section> and <nav>.
Anyone have any thoughts?
I dont think you need the array selector with getElementById so try it on the whole section again and see if that will fix it for you.
So do document.getElementById("intro").style.background='url('+dataUrl+')'

i have downloaded an html template and it has a banner after the nav bar, i am trying to replace the image banner with my image, i changed it to the same size of the image in the template and added, the html is like below:
<div class="single-creative-shop-banner parallaxBg bg-img" style="max-width:100%; height:auto;"
data-bg="assets/img/home-banner/home_shop_creative_01.jpg">
<div class="container">
<div class="row">
<div class="col-lg-12 text-center">
<div class="creative-shop-banner-content">
<h2>Minimal Collection</h2>
<p class="mb-0">Unlock The Goddess In You</p>
</div>
</div>
</div>
</div>
</div>
the css is so long , not able to post in the question, my website is https://likhaa.com
the problem is when i am adding the banner image, its not properly displaying, instead some part is hiding under the navbar, and the width is also not proper. is there any code in html to fix it or can anyone help me with my code
Please remove the inline margin of 131px from the div having the class "shop-creative-banner" also remove position fixed from the div which is children of div having id "jarallax-container-0"
I have experienced problem I have never faced before and even googling it did not help.
I have basic code from the official page of script TurnJS, which is the problem I have with.
<div id="flipbook">
<div class="hard"> Turn.js </div>
<div class="hard"></div>
<div> Page 1 </div>
<div> Page 2 </div>
<div> Page 3 </div>
<div> Page 4 </div>
<div class="hard"></div>
<div class="hard"></div>
This works as it should but is has transparent background so when you have any text on pages it overlays themselves so you cannot read the text properly.
When I add
#flipbook div{
background: white;
}
It somehow breaks. Pages skew when hovered etc.
I cannot insert a jsfiddle example because the link for turnjs script is not https and I am not allowed to insert http links. And here it shows me error in code.
The skewed page is shown on image below.
Does someone know how to add a bg-colorto that flipbook?
I would aprreciate any comments.
You can add another class to your pages which specifies a background colour:
<div id="flipbook">
<div class="hard"> Turn.js </div>
<div class="hard"></div>
<div class="pageStyle"> Page 1 </div>
<div class="pageStyle"> Page 2 </div>
<div class="pageStyle"> Page 3 </div>
...
And then specify everything you need in that class. The other method is to load background images for each page. This is generally how a magazine would be created in TurnJS as it's easier to automate.
Although I just went over their docs looking for this (I know it works, I've done it before) and couldn't find much about it.
Background/skill: I am starting to test out using bootstrap 4 (first time using bootstrap) for a custom Wordpress theme. I have the basic understanding of HTML and CSS, but with the newer CSS and with any jQuery or javascript, I am fairly clueless and usually just hacking code I find online to try and make it work for me, with little understanding of how/why it works if I succeed.
Missing out a bunch of page header info link links to scripts and stuff which I do understand may eventually affect any suggested method, and just to keep it simple. For now I have the following HTML so far:
<div id="page" class="site">
<div id="header" class="container-fluid">
<div id="masthead" class="site-header row row-eq-height">
<div id="logo" class="col-sm-4 col-md-6 col-lg-3"></div>
<!--logo-->
<div id="fruits" class="align-self-center d-none d-md-block col-md-3 col-lg-6"></div>
<!--fruits-->
<div id="social" class="d-none d-md-block col-md-3 col-lg-3"></div>
<!--social-->
</div>
<!-- #masthead -->
</div>
<!--header-->
<div id="jumbotron" class="row">
<div id="notice" class="align-self-center col-md-3"></div>
</div>
<!--jumbotron-->
<div id="content" class="site-content"></div>
<!-- #content -->
<div id="footer" class="container-fluid">
<footer id="colophon" class="row"></footer>
<!-- #colophon -->
</div>
<!--footer-->
</div>
<!-- #page -->
The jumbotron has a background image and a div (#notice) inside it which will float to the left with some text inside. I want the div to take up all remaining viewport space after the header. I have managed to get the jumbotron div be the height of the viewport minus the header using the following CSS:
height:calc(100vh - 155px);
But this only works if I know the height of the header is 155px. In reality, it changes at different screen widths and depending on content.
Is there a way to set the CSS to use a calculation for the dynamic header?
If not, do I need to use some kind of jquery or javascript? If so, I would be very grateful for some fairly detailed instructions.
Note: I do not want the #jumbotron to be the height of the page and sit behind the header div as a solution because the background image display is important.
Thank you in advance :)
Since you can't know easily the height of the header in every device because it is a percentage of the height... And because it depends on a big bunch of CSS rules form BootStrap and your Wordpress theme... You will just measure it to deduct the remaining space.
<script>
$(document).ready(function(){
function adjustJumbotronHeight(){
var headerHeight = $("#header").outerHeight();
var viewportHeight = $(window).innerHeight();
var remains = viewportHeight - headerHeight;
$("#jumbotron").css({"height":remains});
}
// On page load
adjustJumbotronHeight();
// On resize (or mobile orientation change)
$(window).on("resize",function(){
adjustJumbotronHeight();
});
});
</script>
I just implemented imageScroll.js on my website and for the images in between my paragraphs it works fine. When entering the website I would like to have the first image with the parallax effect as well. The images are either loaded via the data-image html tag or via image option (JS).
When I set the image as "background", I think the image is fix and the parallax effect can't be applied. But when I load the image into a div, as I do it with the other two images in between my paragraphs, it shifts the menu as well as the welcome text below.
I tried to realize it with z-index, but couldn't make it run yet.
Does anyone of you have an idea for me how I could make this happen?
Thanks a lot in advance!
Eric
I didn't see the wood for the trees. Just had to put everything inside the div from the parallax:
<div class="img-holder" data-image="../images/other/home-min.jpg" data-image-mobile="../images/other/home-min.jpg">
<!-- Home Page -->
<div id="home" class="container-fluid">
<div class="row">
<nav class="navigation">
<div class="col-md-3"><a class="navigation" href="#about">About</a></div>
<div class="col-md-3"><a class="navigation" href="#portfolio">Portfolio</a></div>
<div class="col-md-3"><a class="navigation" href="#contact">Contact</a></div>
<div class="col-md-3"><a class="navigation" href="#blog"></a></div>
</nav>
</div>
<div id="welcome" class="row">Welcome</div> <!--Welcome Text-->
</div>
</div>
maybe someone else is also confused and perceive this as helpful.
Cheers

I'm using picturefill to do responsive images. The issue that I am having is that I am calling picturefill(); method on the success callback of an ajax call. When the dynamically loads, picturefill is called.
This works fine but the issue is that the picturefill'd picture covers up all of the elements that are overlayed on top of it for about 1 second. this causes an uncomfortable effect because the overlayed elements shows up abruptly. so the sequence is that we see the elements, elements dissapear, and then elements reappear from under the picturefill'd picture.
has anyone else run into this problem and does anyone have any suggestions on how I can deal with it? I already tried changing the z-index of the picture fill'd pictures to z-index:1 and everything else to z-index: 200 but still no luck.
Adding some code:
<!-- Begin centerimage Container -->
<!-- Begin rightcaption -->
<div class="rightcaption">
OVERLAID CAPTION
</div>
<!-- End rightcaption -->
<!-- Begin flip-container -->
<div class= "flip-container">
<div class= "flipper">
<div class= "front">
<div class="main-pic-wrap" id="bloop">
<div data-picture data-alt="name" data-class="relative_image">
<div data-src=source> </div>
<div data-src=img2%> data-media="(min-width: 480px)"></div>
<div data-src=img3%> data-media="(min-width: 767px)"></div>
<!--[if (lt IE 9) & (!IEMobile)]>
<div data-src="medium.jpg"></div>
<![endif]-->
<!-- Fallback content for non-JS browsers. Same img src as the initial, unqualified source element. -->
<noscript>
<img src=img3 alt="Image of Activity">
</noscript>
</div>
</div>
</div>
<div class = "back">
<div id="map"></div>
</div>
</div>
<!-- End flipper -->
</div>
<!-- End flip-container container -->
<div id="moreShowHideGroup">
<div id="mapShowHide" class="icon-globe"></div>
</div>
Alright - finally figured it out. So I believe what is happening is that the container which is holding my picture fill'd picture and my position:absolute floating element is losing it's width property on execution of picturefill since I think picturefill.js removes the picturefill div from the DOM and then replaces it.
While it's removed, the container element which I have set to width:100% has nothing inside to give it an actual width so it collapses for a split-second and my fixed position elements dissapear for a split second.
To prevent this, I put another position:absolute div with 100% width into the container and then dropped my other position:absolute divs into this new container. So the structure looks like this:
<div class="main" style="position:relative">
<div data-picture data-alt="name">div data-src=source> </div></div>
<div class="always-here" style="position:absolute" top:0; left:0;>
<div class="fixed" style="position:absolute; top:2%; left:2%; ">
</div>
</div>
</div>
