display: none in <iframe> specific element - css

In my html webpage I insert an iframe
but in this iframe bottom show a div which's class name mobile-desktop-link

So you want to hide the "view web version" link? Alright, than you can use this:
.mobile-desktop-link a.home-link { display: none; }
Add this to your stylesheet and you are ready to go. Of course this is only possible if the iFrame is on your domain. If you have tried the snippet I shared here above, with or without !important statement and it did not work? Well than, you can't remove it.

how to disable header media in wordpress?

I am facing header media issues. I don't want that header area on my top of the website. I tried CSS code
.home #wp-custom-header {
display: none;"
}
but it's not working. please check my site for more details hindizone.in
It would be a better solution to change your theme template file so there is no such div container to be hidden. This can normally be found in header.php file of your theme. Delete the div with the class header-bottom.
Another way would be using CSS as you already tried. But you do not have an element with id wp-custom-header so this code is doing nothing. You can find out the right element to target with using the inspector of your browser.
I did this with your code and therefore found the classes you need to address in your css file.
Add following code to your custom css in the theme editor, or inside style.css of your theme:
#site-header.top-header .header-bottom {
display: none !important;
}
With the !important statement you make sure, that the display value is not being overwritten somewhere else in your stylesheet.
#site-header {
display: none;
}
...should work for your site.

How do I show a div on fancybox load

I have a page that contains CSS that hides a div class
.sectiondiv.showhide {
display: none;
}
But when loading the same page within a fancybox iframe I'd like to have that same content to be visible. I've tried the following CSS in the jquery.fancybox.css but that doesn't help. Any suggestions for this fix?
Why don`t you simply check if page is inside fancyBox iframe and just add custom CSS if needed? You can create links like 'mypage.html?fancyboxed=true' to make checking easier.
Another solution would be to use aferLoad callback to access iframe contents and do some modifications.
This is how you can access some element within iframe:
$.fancybox.getInstance().current.$content.find('iframe').contents().find('body')

Css–selector for when a html-document is inside an iframe?

I'm trying to make a css-selector that assigns diffrent properites based on weather the html is inside an iframe or not. I tried this:
html:not(:root) body {
background: black !important;
}
I expect this to apply background: black; to the body if it's inside an iframe, but it doesn't, why? And are there any css options? I could always check with javascript if html is root.
IE8 support not requierd.
CSS is only scoped within the same document. An iframe is an entire document in its own right, and so a CSS rule that applies to the page that contains that iframe cannot apply to the page that's within that iframe.
This means that as far as HTML and CSS are concerned, html is always :root (and therefore can never be :not(:root)).
Unless you are able to transfer this CSS from the containing page to the page within the iframe (using a script for example), I don't believe there is a way using just CSS.
It is probably possible to do the styling in an iframe with JavaScript.
document.querySelector('iframe').contentDocument.body.querySelector('#some-element').style.background-color = 'red';
IMPORTANT: Make sure that the iframe is on the same domain, otherwise you can't get access to its internals. That would be cross-site scripting.
Accessing elements inside iframes with JavaScript document futher here: Javascript - Get element from within an iFrame
Posting my comment as an answer for better display, you should:
Put "is in iframe" detection code in JS, as I don't see any other way of doing so
Put CSS code inside the iframe depending on the JS result
So if all code is inside the iframe, do:
if (window.parent !== window) {
document.documentElement.classList.add('inside-iframe');
}
html.inside-iframe {
bkacground-color: black;
}
If you want the detection-JS-code to be inside the parent frame, go for:
document.querySelectorAll('iframe')
.forEach(i => i.contentDocument.documentElement.classList.add('inside-iframe'));
Assuming the iframe is loaded when executing this JS (otherwise, contentDocument/documentElement will not exist). You may rely, in such case, on load event of the iframe (but it seems better anyway to put "is-in-iframe" detection indise the iframe itself, as the corresponding CSS is inside the iframe too)
html:not(root) body {
background: black !important;
}
Works

Avoid overriding by css

I have created a UI (for wordpress plugin) in which I give user choice to add text, image, and video in a div ( lets call this div, container).
I have been working on it for a quite sometime. I recently added tinyMCE (WYSIWYG editor) to add text inside container.
Now, I realized that I did a big mistake. The text user writes is being overridden by css rules defined for wp admin panel.
for example,
User enters <h1>Hello</h1> (with the help of tinyMCE), and then I grab that content from tinyMCE and append that in the container.
But here the problem arises, wordpress's admin css can have css rule like this,
h1 {
color : #d6d6d6;
line-height: 40px;
font-size: 30px;
}
So, it looks different in tinyMCE and in my container. (as tinyMCE's code is inside iframe and that remains unaffected by wordpress's css rules, but my container doesnt)
I want something so that any element inside container remains unaffected by wordpress's admin css.
I know a good solution would be putting container inside iframe. But I have written a lot of code without thinking of an iframe and I would need 3-4 days just to adjust everything for iframe. There may be some cross browser issues.
I can reset some wordpress rules, but it will fail sometimes, as user may enter anything. I need something fullproof.
well if you want to undo a specific rule (say the h1 rule you mentioned) you can use css to override it by being more specific.
.container h1 {
color:#000000;
line-height: 24px;
font-size: 24px;
}
This will overwrite the css rule you mentioned with the given values but only when the element is inside the container class, (I'm guessing at the default values you want to use.)
Unfortunately you would have to add in an undo rule for everything that wordpress's admin css changes.
Another possible solution is to edit the page tinyMCE returns in it's frame to add in wordpress's CSS file. This means the end user will see the same formatting when they enter the information as when it gets posted.
Do you have code-level access to the iframe contents tinyMCE creates?
Use !important in your CSS document. This way your CSS will not be overridden as it takes precence over everything, including inline styles.
h1 {
color:#ff0 !important;
}

Independent CSS for Fancybox

I have a page from which I call fancybox which contains some html template (something like an email template). The problem is that all CSS from the main page affects the content in the fancybox and vice versa. What I would like is to isolate them somehow, so that their CSSs don't affect each other.
Example: I have background image set for h3 for the main page. Also, in fancybox I have h3 element which has no CSS assigned to it, but it pulls the style from the main page and gets the same background image (which shouldn't happen).
Is this somehow possible?
You could split your CSS into multiple files, only pulling in what you need to for each html. If you aren't able to do that you can give the body a specific #id for your template that gets loaded into the fancybox.
<body id="fancy_content">
and then adapt your styles for that template
body#fancy_content h3 {
color: green;
}
You may still end up with a bit of style clash if you leave it in one file but this will give you a method to go on to get it working.
You have 3 options really.
Run the fancybox content in iframe mode which means the content will have to be on it's own page without the main stylesheet. You can do any styling you like here or none at all.
Reset styles in the fancybox content, though this may be quite tedious depending on the number of elements affected.
Place the fancybox content outside the main #wrapper div of your page, and make all page styles inherit from #wrapper. i.e. instead of h3 {...} use #wrapper h3 {...}
try adding IDs to your html elements then use CSS IDs
h3#idname { color: #FF0000; }
