iPhone/iPad background image on wrong element - html

I have an issue where, ocassionally, when I set a background image on an HTML element it displays a completely random image that is also set as a background image elsewhere on the page.
For example, I have a list item that has a background image "myimage-abc.jpg".
I also have a div with a background image of "myimage-123.jpg". Everything is as expected for most people however for some Apple users (of which my Managing Director is one) the image "myimage-123.jpg" shows up on the list item as well as the div.
Has anyone else had this issue before? Any ideas how to get around it?
Thanks

Use inspect element on the element with incorrect background image and see which CSS selectors are overriding the background image that you want to have.
Then report back with the CSS selectors responsible for styling the elements in here. Keep in mind that CSS selectors are very particular about the way in which you use them.
Until then here's something that could be causing your problem, without my knowing your current CSS state.
From an answer on another question:
I've dealt with this before and it's always a strange issue. So here are some thoughts and examples of CSS behavior.
In CSS we have a hierarchy decided both on how you select an element and on its position within your stylesheet. Take for example the following CSS selectors:
body .test-parent .test-child {
color: red;
}
body .test-parent .test-child {
color: blue;
}
The result in this case would return color: blue; as the final style as it is the last read declaration for that elements color value.
However if we declare the following:
body .test-parent-two .test-child-two {
color: red;
}
body .test-child-two {
color: blue;
}
Then the final value is color: red;. This caught me off guard and it took me a while to notice the pattern and fix.
The problem here lies in the selectors. A more in-depth selector (longer / includes more in-between children) will override any others as can be seen by this JSFiddle.
Hope that also helps!

Force/3dTouch gesture on iphone gives weird background for <a> element

I have button which is <a> element with href, which doesnt have any background set on :active/:focus/:visited, but on force/3dTouch tap it gets this weird #b8b8bc background under the text only (while <a> doesnt have any children e.g. <span> etc so I suppose this is the text node highlight).
here's the gif to illustrate the behavior.
I've tried adding -webkit-tap-highlight-color: transparent but it changes only regular tap color, not the forced/3d one
also I thought maybe that's selection color (as I can reproduce this on various websites) so tried to use selection selectors which didn't help as well
::selection {
background: transparent;
}
::-webkit-selection {
background: transparent;
}
::-moz-selection {
background: transparent;
}
Any ideas about possible origin of this?
Good job digging up.
I had the same issue plus another one and here are my solutions.
Post is old but someone could find it useful like me today.
First of all, the forced background was covering my link text totally because I was using user-select: none; on my header links.
So that's something to check, just in case.
Regarding the background color, Force Touch doesn't use the link parent element background but the one that's under it.
If you want to "feel it", we could say that Forced Touch digs into the direct parent background and let the under layer appears.
So, to counter that without having to touch to background color, I use some z-index in the parent element to elevate it, preventing Forced Touch to "dig" :)
So if your links parent element is named card, you can add to your CSS:
.card {
isolation: isolate;
z-index:1;
}
Now, Force Touch will use the parent background color as we want to.
Okay so I found sort of "solution" based on parent's color.
Try to set *{background: red}.
If worked try set same on few parents .parent1 { background: pink}, .parent2 { background: lightblue}, .parent1 { background: salmon} etc.
In my case I found the color applied to force touched text was menu wrapper's background that takes most of the screen when menu is opened.
Side effect of this change - all forcetouched elements will have same color, no option to specify :hover or :active colors (you can see the color is slightly different on the 1st click) and ALL links will have same background:
I imagine you can try setting wrapper's background via JS based on what is clicked. Not sure if that will work. see docs here:
WebKit DOM Programming Topics
So far this seems to me too fragile to touch and I would not recommend doing this. Though you can change this color I've decided to let OS do what it wants here.

Can't identify CSS or element controlling background color

I'm having trouble changing the background color of a certain button on a WordPress plugin.
The button and text are set to white and I'm trying to identify the CSS file that controls it, unfortunately I've had no luck within the inspect element of my browser.
It is incorporated in a popup form - so multiple other files come into play.
I changed the color within the browser during inspect but need a fix.
You can overwrite CSS attributes by setting !important after your definition or by defining the scope better (e.g. by writing body or html before the class selector).
make sure your css file is able to "access" the dom element – if the element is in an iframe the css wont work.
body .wpforms-page-button {
background-color: green !important;
}
Using !important is generally considered hacky. Both rules in your screenshot have the same CSS specificity in that they are both firing on input[type="submit"] and .button.
Without seeing the corresponding HTML I can't give you the exact syntax, but something like
.parentclassname input[type='submit'] and or .parentclassname .button should make your style more specific than the original rule and therefore give it precedence.
Did you try to set !important after the #fff; ?
like this:
input[type=submit] {
background-color: #fff!important;
}
the best way is to define the button in a class, so you can change only the color for this specific button. Otherwise it will changes all the buttons to color #fff if you put the css in a general style.

unwanted block appears over text when div size is

On our site http://reiner-lemoine-institut.de/ueber-uns/team/kathrin-goldammer/, whenever the window is minimized to a certain size, a blue block appears over part of the text.
I have added a screenshot that specifies the exact place within the code that seems to be affected. I am not an expert in CSS or HTML, so I am hestitant to change the code myself:
Apparently though, the problem appears when the div.column_attr = exactly 339.833 x 908. Anything below this size or above it is fine.
I had a play around with your CSS and think I found what your problem is.
.get_in_touch, .infobox {
background-color: #0f3b64;
}
if you remove/comment out this background-color your problem should be fixed.
This is caused by the following line:
.get_in_touch, .infobox {
background-color: #0f3b64;
}
Change to transparent should solve the problem:
.get_in_touch, .infobox {
background-color: transparent !important;
}
Your theme has a custom.css file to put your custom styles in it and is located at: css/custom.css so try to add the above code there.
I have a answer for your question. The following class has a background color in your css file. You can remove thet color if not required in the website.
.get_in_touch, .infobox{background-color: #0f3b64}
Or you can use where inline background image is define i.e in infobox
.infobox{background-size:cover;}

Difference between <a> and <button>

I recently modified a bit of a button to give it a 3d effect in a bootstrap site.
The result satisfied me, but when I applied the style to tag <button> instead of <a> I had several problems.
You can find the code in question here: http://jsfiddle.net/wctGM/3/
I hope someone can help me, because I can not in any way to move forward
You must use border: none:
button {
border: none;
margin-top : 50px;
}
Your code:
http://jsfiddle.net/wctGM/7/
There are some things which are different to each other. For an instance if you set the border:none; property for a button you will get rid of that border. But the width and height remains different. What I mean to say is go through the default properties which are set on each html tag and try to understand them and then try to change.
See this link. I have added border property like below.
button {
margin-top : 50px;
border:none;
}

target multiple html properties with css:hover

I'm trying to use the css hover, and I have it working on a div by doing:
#complete-paper:hover{
background:url('/static/images/blue-aarow.jpg') no-repeat;
background-position:192px 35px;
background-color:#17aedf;
color:#ffffff;
}
my question is, is there a way to target another html element, like a totally unrelated div, when I hover over the property with the ID of complete-paper? So when you hover over the div with complete-paper, it'll do the above hover css changes, as well as change another div on the page?
Thanks
Edit: The question I had is if it's possible if the div's are unrelated. But in this case they are related, It's actually a p inside a div when you hover over the div, I want the p to also change
Not unless the other div is nested in #compete-paper where the css would look like:
#complete-paper:hover{
background:url('/static/images/blue-aarow.jpg') no-repeat;
background-position:192px 35px;
background-color:#17aedf;
color:#ffffff;
}
#complete-paper:hover .other-div{
/* different css */
}
Not unless the other div is a descendant or sibling of the hovered element.
Since you said it's a descendant, then do it like this:
#complete-paper:hover #decendant_id {
// stuff
}
While the actual HTML elements in the file must be either nested or contained in a single element to be valid ':hover' targets to each other, the css 'position' attribute can be used to display any element where ever you want. I used position:fixed to place the target of my ':hover' action where I wanted it on the user's screen regardless to its location in the HTML document.
So the element is where the browser wants it in the code, and where the user wants it on the screen.
