Best way to hide previous border? - css

I have a menu with several div. Every div has a 1px left border. On hover, I change the background of the current div, but as you can see with the following JSFiddle, it's ugly that the previous (grey) border is still visible.
I would like to hide it when I'm on the current selected div. Any ideas?
Fiddle
<div id="main_menu">
<div class="menu_item"><div class="link">Example</div></div>
<div class="menu_item"><div class="link">Example</div></div>
<div class="menu_item"><div class="link">Example</div></div>
<div class="menu_item"><div class="link">Example</div></div>
</div>
To make it more clear, from this:
To this:
Possibly without using any JS.

Change your .menu_item hover css to this:
#main_menu .menu_item:hover {
background-color:#00437f;
cursor:pointer;
position:relative;
left:-1px;
}
and to maintain text at its position update below css:
#main_menu .menu_item:hover .link {
color:#fff;
border:0px;
position:relative;
left:1px;
}

CSS on hover image blinking issue

I tried to make a simple CSS hover but got a blinking image issue. Is there something I can do to fix that?
In the meantime, there is a empty gap between a H3 title and .term-image class because of my CSS settings for a class (.term-desc). Is there a way to eliminate this gap? It appears that the gap created by position:relative is not easy to be removed.
I need to hide the image when mouse hovers.
http://jsfiddle.net/fveqkcnj/
<div class="categorywrapper">
<div class="views-row views-row-1 views-row-odd views-row-first">
<h3 class="term-title">
Arts & Culture
</h3>
<div class="term-desc">
<p>This is Arts & Culture</p>
</div>
<div class="term-image"> <img src="http://placehold.it/235x150/ffffee" />
</div>
</div>
.categorywrapper {
width: 720px;
clear:both;
}
.categorywrapper .views-row {
float:left;
position:relative;
width:235px;
}
.categorywrapper .views-row h3 {
position:relative;
margin-left:30px;
border-bottom-width: 2px;
border-bottom-style: solid;
border-bottom-color: #000;
width:80%;
min-height:38px;
}
.categorywrapper .views-row .term-desc {
position:relative;
top:100px;
left:20px;
width:200px;
}
.categorywrapper .views-row .term-image {
position:relative;
}
.categorywrapper .views-row .term-image:hover {
z-index:-2;
}
Add to your css: pointer-events:none; in the .categorywrapper .views-row .term-desc
Basically the result is:
.categorywrapper .views-row .term-desc {
pointer-events:none;
position:relative;
top:100px;
left:20px;
width:200px;
}
Additionally you use a negative z-index on your hover element which means it goes behind the parent elements and triggers the mouseout event which turns off the hover.
You can fix that by instead of applying the following css to the row instead of the image:
.categorywrapper .views-row:hover .term-desc {
z-index:2;
}
Here is the JSFiddle
If you want it over the image do the same but put the .term-desc element inside the tag.
I've never used z-index for image hovers, but I would imagine that if you move the z-index down, the browser no longer considers you to be hovering over the image, so you get the blinking effect you mention. Try producing your hover effect using an alternative background image instead. Or else by changing opacity.
I assume your intention is to show the text when hovering the image. If that is true, you've chosen not only a cumbersome approach, but also one that doesn't work.
Since your image is wrapped in a div already, it is extremely easy to achieve your goal: Just put the div with text that should appear inside the same container that has the image. Apply proper positioning and give it a default opacity: 0; so it's initially invisible.
Then
.categorywrapper .views-row .term-image:hover .term-desc {
opacity: 1;
}
To also get rid of the unwanted whitespace between your h3 and your image, just set the h3's margin-bottom: 0;

How do I hide the underlying text of a div without background color?

I'm trying to overlay two div elements, the underlying has a background the overlaying can not have one, since later there will be a background image in the back.
I want the underlying text to be cut off at the place where it is behind the overlaying div.
The only way I found was to set background-color: white; to the overlaying div, as mentioned this is not possible.
Any tip/solution how do I accomplish this?
<div style="background-color:red;z-index:1;overflow:hidden;position:absolute;left:262px;top:222px;width:191px;height:48px;">
This is a TEST text.
</div>
<div style="border:1px solid black;z-index:2;overflow:hidden;position:absolute;left:152px;top:177px;width:199px;height:156px;">
Top Element
</div>
Would this work for you? Basically, I've added a third div with the background color white that you can set it's display to none when the image goes into the lower div. This is mainly just a thought, it can probably be applied to the lower div instead.
<html>
<head>
<style>
#botDiv{
background-color:red;
z-index:1;
overflow:hidden;
position:absolute;
left:262px;
top:222px;
width:191px;
height:48px;
}
#topDiv{
border:1px solid black;
z-index:2;
overflow:hidden;
position:absolute;
left:152px;
top:177px;
width:199px;
height:156px;
}
#interSectingDiv{
background-color:#fff;
position:relative;
top:26px;
left:109px;
overflow:hidden;
width:191px;
height:48px;
display:block;
}
</style>
</head>
<body>
<div id="botDiv">
This is a TEST text.
</div>
<div id="topDiv">
Top Element
<div id="interSectingDiv"></div>
</div>
</body>
</html>
[ updated ]
Another thought, is that you can probably shorten the width of the lower div by the amount of space it consumes from the higher div and position it at the right edge of the higher div until the image goes in (you'll most likely have to use animation in your css that's triggered by some form of javascript).

fixed position of button above image

I have a problem with my webpage. I placed a button on top of an image inside a scrollable <div></div>, and this <div></div> is inside the <td></td> of the table. The button on top of image has the following CSS styles:
border:none;
background-color:transparent;
color:#FFF;
z-index:101;
top:2px;
background-image:url(count.png);
background-size:40px;
width:40px;
height:40px;
padding:0 15px;
font-size:16px;
margin-left:-5px;
cursor:pointer;
position:absolute;
Now the problem is when I scroll down, the button stays on the same position. What I want is when I scroll down the button hides on top together with the image at the same position. How can I make this? Any help would be so much appreciated.
jsFiddle: jsFiddle
The issue that you might be facing is something like positioning. You are position the image position: relative to the div, Not the image. If you wrap the image in a div and then set the position then it will go up too.
However, that is only the issue, try using something like:
<div class="image-div>
<img src="src_to_file.png" alt="photo" />
<button class="button">Button</button>
</div>
You can use this as the css:
.image-div {
position: relative;
}
.button {
position: absolute;
}
Also make sure that .image-div is not the main or parent div, as if it is! The button will float over it, but if the div .image-div is the child, it will slide (scroll).

highlight div1 and div2 on div2 mousover, highlight nothing on div1 mouseover

Div highlighting question
I have 2 divs stacked on top of each other inside a container.
Here is the behavior I want: when you mouseover the top div, nothing happens. when you mouse
over the bottom div, the top div background changes color, and the bottom div's background
changes a different color. In the sample code I tried, mousing over the container div makes
the top turn green and the bottom turn vlueviolet. I want a mouseover on the bottom to cause
this behavior, but I want a mouseover on the top to do nothing. I feel like I could get this
done in jQuery using a parent selector or something, but it seems like I should be able to
do this in pure CSS. Thanks!
Here is what I've tried, which of course doesn't work, but gives an idea of what I'm trying to do.
<html>
<head>
<style>
div
{
display:inline;
border:1px dotted black;
font-family:Courier;
background:white;
}
div#outer{
display:inline-block;
border:2px solid red;
}
div#outer:hover #top{
background:green;
}
div#outer:hover #bottom{
background:blueviolet;
}
div#top:hover, div#bottom:hover{
background:white;
}
</style>
</head>
<body>
<div id=outer>
<div id=top>
top
</div>
<br>
<div id=bottom>
bottom
</div>
</div>
</body>
</html>
I changed up your CSS a little bit. Basically to make it bigger.
The order is important here.
This is not perfect due to the outer div's border.
<style>
div {
border:1px dotted black;
font-family:Courier;
background:white;
}
div#top, div#bottom {
height: 200px;
width: 200px;
}
div#outer:hover #bottom:hover {
background:blueviolet;
}
div#outer:hover #top {
background:green;
}
div#outer #top:hover{
background:white;
}
div#outer{
display:inline-block;
border:2px solid red;
}
</style>
Is this what you're looking for?
div#outer:hover div#top:hover, div#bottom:hover{
background:white;
}
Alternatively, you could also use !important:
div#top:hover {
background: white !important;
}
I don't think you can do this... CSS selection only works one way, from parent to child or in cascade.... so you can only change the CSS of divs below another div.
For example look this jsFiddle: as you can see, only the bottom divs' style can change.
This code
div#fourth:hover ~ #first{
background:green;
}
doesn't work because the "first" div is above the "fourth" div...
Anyway, if you want to set the background of top div to white, you will see a rollover with the delay.
PS: Sorry for my bad English.

CSS Tooltip inside scrolling div

I have a simple CSS help popup that's been working well for me in most simple layouts. But now it needs to work inside a scrolling div.
Given the example HTML:
<div style="overflow:scroll; width:80px">
<a href="#" class="tooltip">
an image
<span>some hidden tooltip which is a bit longer in here</span>
</a>
</div>
(Note: in the real world there will be multiple things with tooltips inside the scrolling div)
I have the CSS:
a.tooltip span
{
display:none;
position:absolute;
padding:0px 0px 2px 2px;
background:yellow;
text-decoration:none;
vertical-align:top;
}
a.tooltip:hover span
{
display:inline;
position:absolute;
padding:0px 0px 2px 2px;
top:0;
left:18px;
background:yellow;
text-decoration:none;
vertical-align:top;
z-index:5;
}
a.tooltip
{
border-width:0px;
text-decoration:none;
}
a.tooltip:hover
{
border-width:0px;
text-decoration:none;
position:relative;
}
Is it possible to have the popup pop out of the scrolling div so it's readable without causing the div to scroll?
Is this achievable in CSS alone, without using javascript?
edit: Live Example kindly provided by Kyle Sevenoaks.
You can set the :hover on the entire DIV. and place your span directly in the div. (This solution does not work in IE6 for example).
see a working example here: http://jsfiddle.net/5mASU/1/
Or you could set i higher z-index to the tooltip and use position fixed, it works:
http://jsfiddle.net/5mASU/3/
also avoid resetting the same values in the hover here is a cleaned up version:
http://jsfiddle.net/5mASU/4/
if for example you set
a {
padding: 5px;
}
a:hover {
// no need to reset the padding here
}
you don't need to reset the padding in the :hover the hover heritages the padding form the style set for the a. Just reset values you want to change between the normal and the hover status.
I don't think it's possible, because z-indexes work from the parent, the child element won't be able to display the span over the top. This CSS tooltip just adds another element when the <a> is hovered. I think you might have to go the jQuery route.
Also, try to post live examples of your problem instead of a long list of HTML and CSS, it's easier for us to help you :)
