I am trying to make a table that when mouse hover on the row the first thead row column will change background. I know it can be done using jQuery, I just want to know if I can use CSS only.
Visit http://jsfiddle.net/G9G65/1/
<table>
<thead><tr><th></th><th>Title 1</th><th>Title 2</th></tr></thead>
<tbody>
<tr><th>List 1</th><td>Data 1</td><td>Data 2</td></tr>
<tr><th>List 2</th><td>Data 1</td><td>Data 2</td></tr>
<tr><th>List 3</th><td>Data 1</td><td>Data 2</td></tr>
</tbody>
</table>
<style>
table tbody tr:hover {background: yellow;}
table tbody tr:hover thead tr th {background: red;}
</style>
Unfortunately I don't think you can achieve what you're after with css alone.
Basically you would need a parent's sibling selector to make this work, and no such selector exists.
While you can hover over a parent element and effect a child element, CSS doesn't yet allow interactions with child elements to effect parent elements or a parent element's sibling.
So...
#parent:hover #child { /* this works */
background: green;
}
#child:hover #parent { /* this does not work */
background: yellow;
}

I have this two styles in CSS, both in an external linked css file, and applied to the same table, with class myTable (it's a simplified version of a larger problem):
.myTable th
{
background-color: gray;
}
.myTable tr:nth-child(odd)
{
background-color: blue;
}
When I run the page, the header is gray, but why? What I want to know is why the first rule is overwriting the second. If I understood well specificity calculations (and obviously I didn't) the second rule is more specific (all calculators give me 0, 1, 2 in the second rule and 0, 1, 1 in the first one). Why then, the header is gray and not blue, if the second rule has more specificity???? Could someone help me understand this, please? Thank you very very much...
You forgot th or td:
.myTable tr:nth-child(odd) th,
.myTable tr:nth-child(odd) td {
background-color: blue;
}
Because you are applying for th in your first class, you need to use that here. The th is inside the tr, so whatever you put, th will be in front showing the grey colour.
CSS specificity does not apply in your situation.
Your CSS targets two different elements; th and tr.
You have to think about this from a layer perspective.
Because th's are contained in tr's then the background-color of the th will be displayed above the background-color of the tr.
Take this code for example:
<tr style="background-color: gray">
<th>Heading One</th>
<th style="background-color: red">Heading Two</th>
<th>Heading Three</th>
</tr>
The first and third th have a transparent background-color, so the background-color of the tr shows through them. The second th has a background-color defined so it shows as expected.
You can take a look at this jsfiddle to see it in action.
Your first rule is not overwriting the second rule.
The reason is that your header is grey is because it contains th elements, and you only specified background: grey for the th elements. (And a th is not the same as a tr).
If you want alternating column colors in your header also, then modify your code to address both the th and the td, like so:
.myTable th {
background-color: gray;
}
.myTable td:nth-child(odd),
.myTable th:nth-child(odd) {
background-color: blue;
}
How can I collapse/show a table row using only CSS when I HOVER on the PREVIOUS row. Basically popup more information when I hover over a table row.
Lets say call the "previous row" class .previousRow, and the row you want to change .popUp.
Lets assume that the .popUp's display is display:none; and you can't see it currently.
Try using this in your CSS:
.previousRow:hover + .popUp {display:block;}
This selects the popUp class on the previousRow hover event and changes its display.
You could also interchange that display property to anything else you want to add on the previous row :hover.
Hope this helped!
I think this solve your question:
.table1 tr {
border: solid 1px #000;
display: block;
}
.table1 tr:hover + tr {
display:none;
}
<table class='table1'>
<tr><td>Row 1</td></tr>
<tr><td>Row 2</td></tr>
<tr><td>Row 3</td></tr>
</table>
The selector .table1 tr:hover + tr will select the next row of the row being hovered.
I have two styles, one which is at element level 'td' and another which is at class level '.specialTable td'. And I've run into some problems as the class level style is inheriting all the 'td' style properties if I have not specified them again.
I have a CSS style
td
{
background-color:black;
}
and then I have
.specialTable tr:nth-child(even) {
background-color: white;
}
and
.specialTable td
{
background-color:none;
}
What happens here is that even though I've asked.specialTable td to have no background, it inherits the black background from element style 'td' and this causes my element style 'tr' to be blocked out, because cells are on top of rows.
I am trying to set alternating row style to my table. Please help me with how I can stop the original 'td' element style from getting in the way.
Here is the fiddle:
http://jsfiddle.net/PIyer/phADs/1/
you have a type in your css, but im not sure if that is the problem
specialTable tr:nth-child(even) {
background-color: white;
}
should be
.specialTable tr:nth-child(even) {
background-color: white;
}
aslso background-color:none is not valid css , maybee background-color:transparent
none is not a valid property for the background color. Try this:
.specialTable tr {
background-color: black;
}
.specialTable tr:nth-child(even) {
background-color: white;
}
Or you might use in your example just
.specialTable td
{
background-color: transparent;
}
This should let the white shine through.
You could simplify things, by using basic CSS overriding.
Let's say you have this:
<table class="specialTable">
<tr>
<td>This is an odd row</td>
</tr>
<tr>
<td>This is an even row</td>
</tr>
<tr>
<td>This is an odd row</td>
</tr>
<tr>
<td>This is an even row</td>
</tr>
</table>
And your default <td> style is this:
td {
background-color:black;
color: #FFF;
}
To make alternating (zebra) styling to .specialTable, you can simply do this:
.specialTable tr:nth-child(even) td {
background-color: blue;
}
This will override the original CSS defintion for <td> for all <td> tags within an even <tr> tag.
Check out a working example here: http://jsfiddle.net/rh5vV/
It's important to note that the nth-child sudo selector does not work in versions of IE8 and lower, so you may want to apply a class of .even to your even <tr> tags.
Try this out
.specialTable tr td {
background-color:transparent;
}
using background none is incorrect, use transparent instead
http://jsfiddle.net/RBY2v/1/
You can use background-color:transparent; or depending on background:none;:
.specialTable td {
background-color:transparent;
}
I am new to CSS and am working on an intraweb application which will render in modern standard browsers (IE support is not necessary). I have spent much time looking for answers on this and other sites, only to find the answers "It's impossible because..." or "Do this hack instead...." but I just won't accept that.
Here's what I need:
A table with one header row and multiple body rows;
A solid border under the header row;
Vertical white space (padding? margin? spacing?) between the header row and first body row only;
Body rows being highlighted on mouse hover.
I couldn't get (2) to be visible until I styled the table border-collapse: collapse;. Fine. But (3) apparently only works with border-spacing, and only on <td> elements (not <tbody> or <tr>), which is anyway disabled by the collapse. Meanwhile, for some unknowable reason, margin's are not recognized for <thead>, <tr>, or <th> elements, but having padding-top on the first row of the body's <td>'s works, except it doesn't, because when I mouse over that first row, the whole margin-which-is-implemented-as-padding gets highlighted as well, which nauseates me.
I know having a few pixels of margin between a table's header and body is like a really out-of-left-field, why-would-anyone-ever-want-that thing to want, but what should I tell you? I'm no cheap date.
Please be as brutal and condescending as you can in pointing out my stupidity in understanding CSS, provided you also either 1) say how to do it without changing the markup (thereby preserving the separation of presentation from content CSS was evidently designed to encourage) or 2) agree with me that CSS is weird.
<head><style>
table {
border-collapse: collapse;
border-spacing: 0;
}
thead {
border-bottom: 4px solid #123456;
}
/*** something goes here ***/
tbody tr:hover {
background-color: #ABCDEF;
}
</style></head>
<body>
<table>
<thead>
<tr><th>Fruit</th><th>Color</th><th>Yummy?</th></tr>
</thead>
<tbody>
<tr><td>Apple</td><td>Green</td><td>Yes</td></tr>
<tr><td>Banana</td><td>Yellow</td><td>Yes</td></tr>
<tr><td>Pear</td><td>Brown</td><td>Yes</td></tr>
</tbody>
</table>
</body>
This would fix your problems without any hacks and ofcourse its completely possible. The updated code(only CSS changes) is shared below with explanations.
Problem 3 :
We can make use of the CSS selector :first-of-type(targeting only the first row) in succession with all the <td> under it and use attribute padding-top. Simple :-)
<tr> cannot have margin values by default. Again hacks are available(above mentioned answers) but I wouldn't go there as you don't want it.
And also since we have used padding, the hover effect would work perfectly on the entire row content. Hence getting the desired change without any markup changes.
Problem 2 :
We can remove the attribute border-collapse from table and instead apply the border on the <th>tags (let the border-spacing: 0 remain or the border would be discontinuous). Simple again :-)
Problem 1 and 4 are already covered. No markup changes as you wished. Here is the Fiddle
So the updated style code would look like
<head><style>
table {
border-spacing: 0;
}
thead tr th {
border-bottom: 4px solid #123456;
}
tbody tr:hover {
background-color: #ABCDEF;
}
/*** added ***/
tbody tr:first-of-type td {
padding-top: 10px;
}
</style></head>
Okay, in order:
1: A table with one header row and multiple body rows:
This is what the elements thead and tbody were designed for:
<table>
<thead>
<tr><th>heading one</th><th>Heading two</th></tr>
</thead>
<tbody>
<!--
all body table rows in here
-->
</tbody>
</table>
There's also tfoot (see references), which, if used, must be declared before the tbody element.
2: A solid border under the header row:
thead tr th {
border-bottom: 2px solid #000;
}
Select the th elements within the thead element, the tr selector is probably unnecessary here, and, while it does no harm, can be simplified to: thead th {/*...*/}.
3: Vertical white space (padding? margin? spacing?) between the header row and first body row only. padding, it seems, cannot be applied to the thead, tbody or tr elements, since they're, essentially (I suppose) 'non-visual', so it has to be defined on the td elements. This does, on hover, mean there's a disconcertingly large 'row' occupied by the first row during the :hover (see the next part).
tbody tr:first-child td {
padding-top: 1em;
}
4: Body rows being highlighted on mouse hover.
tbody tr:hover td {
background-color: #ffa;
}
While you can apply a :hover to the currently-hovered cell, and later siblings (with the general sibling ~ combinator) you can't apply a style to siblings that appear previously, so here we're styling the td elements in response to the :hover of their parent tr.
The reason that we have to style the td (rather than directly change the background-color of the tr is because td elements don't typically default to a transparent background, which means the changed/highlighted background-color is 'hidden' by the background-color of the td elements.
JS Fiddle demo.
References:
Table row-groups, thead, tbody, tfoot elements.
In order to apply margin to the first table row you need to make it display: block; first, as margin can only be applied to block elements (including inline-blocks)
But here is another solution using positioning:
<head><style>
table {
border-collapse: collapse;
border-spacing: 0;
position: relative; /* Add positioning */
margin-top: 40px; /* Add some margin */
}
thead {
border-bottom: 4px solid #123456;
}
/*** something goes here ***/
thead {
position: absolute; /* Position this element absolute */
top: -40px; /* And move it up */
}
tbody tr:hover {
background-color: #ABCDEF;
}
</style></head>
<body>
<table>
<thead>
<tr><th>Fruit</th><th>Color</th><th>Yummy?</th></tr>
</thead>
<tbody>
<tr><td>Apple</td><td>Green</td><td>Yes</td></tr>
<tr><td>Banana</td><td>Yellow</td><td>Yes</td></tr>
<tr><td>Pear</td><td>Brown</td><td>Yes</td></tr>
</tbody>
</table>
<p>Thats how its done!</p>
</body>
Basically we apply position: relative; to the table and position: absolute; to thead.
Now you can move the thead inside the table using top, bottom, left and right properties. We are going to move it up by 40px using top: -40px;
We do not apply position: absolute; to tbody, because if we do - this element will no longer 'strech the page' or in other words all the following elements will ignore its height. (try doing it and see what happens to the following block)
The only thing we got left - is to apply some margin-top to the table itself, moving it down (as we moved the thead up)
Yes, CSS can seem a bit weird from time to time, but this is mostly because we forget how some page elements are supposed to be handled (namely tables and their child elements)
What about adding an empty row at the beginning like
<tbody>
<tr><td> </td></tr>
<tr><td>blablablabla</td></tr>
And use this CSS
tbody tr:first-child td{
padding-top: 15px;
}
tbody tr:first-child:hover{
background-color: transparent;
}
So the padding will be added to first row and first row won't highlight on mouse over? :)
All your 4 points are covered there-
First download metro ui css here http://metroui.org.ua/
Include its two css file 1. metro-bootstrap, 2.metro-bootstrap-responsive into your project.
Register that in BundleConfig.
bundles.Add(new StyleBundle("~/Content/css/metroUI").Include("~/Content/css/metro-bootstrap.css",
"~/Content/css/metro-bootstrap-responsive.css"));
Now use class "gr-items" for table
< table id="divAllActivities" class="gr-items">
<thead>
<tr><th><span>Comment</span></th></tr>
</thead>
<tbody>
<tr>
<td><span>OperationDateTime</span></td>
</tr>
<tr>
<td><span>OperationDateTime</span></td>
</tr>
</tbody>
Hope this is what you want.
I want to give good background effect to rows using this css
tr:hover td{background-color:#ddd; }
imagine a table inside a table,
naturally all td's inside, also effected by this css. How can I prevent?
<table
<tr
<td -->color change is good
<tr
<td
<table
<tr
<td --> color change is bad
I tried using
form>table>tr:hover td still same
form>table>tr:hover>td not working at all
thanks for help
Use this to style only your outer tds on hover.
form > table > tbody > tr:hover > td {
background-color: #ddd;
}
Notice the tbody selector. See this answer for why it's needed.
Use a second selector:
tr:hover table td { background-color: black; } /*change to default*/
