Change the color of buttons designed by table with CSS - css

Considering the following code displaying two different buttons structured by a table (<tbody class="btn btn-left"> is a button and <tbody class="btn btn-right"> is another button:
<table>
<tbody class="btn btn-left">
<tr>
<td class="btn-tl"></td>
<td class="btn-tc"></td>
<td class="btn-tr"></td>
</tr>
<tr>
<td class="btn-ml"></td>
<td class="btn-mc"></td>
<td class="btn-mr"></td>
</tr>
<tr>
<td class="btn-bl"></td>
<td class="btn-bc"></td>
<td class="btn-br"></td>
</tr>
</tbody>
</table>
<table>
<tbody class="btn btn-right">
<tr>
<td class="btn-tl"></td>
<td class="btn-tc"></td>
<td class="btn-tr"></td>
</tr>
<tr>
<td class="btn-ml"></td>
<td class="btn-mc"></td>
<td class="btn-mr"></td>
</tr>
<tr>
<td class="btn-bl"></td>
<td class="btn-bc"></td>
<td class="btn-br"></td>
</tr>
</tbody>
</table>
The css is working but doesn't target the td, which I need to
.btn-left {
background-color: red;
border-color: red;
}
.btn-right {
background-color: blue;
border-color: blue;
}
How would you set up the css so that one button displays a color and the other button displays another color ?
Thank you for your help.


at first - you must use the table tag.
Then put following classes in your Stylesheet:
.btn-left { color: blue; }
.btn-right { color: red; }

Table background color and responsive to mobile on Next.js using Tailwindcss

I have this table example from Tailwind. I want to change the background color for the even number of the item.
#layer utilities {
.no-scrollbar::-webkit-scrollbar {
display: none;
}
.no-scrollbar {
-ms-overflow-style: none;
scrollbar-width: none;
}
.tr:nth-child(even) {
background-color: #ccc;
}
.tr:nth-child(od) {
background-color: #fff;
}
}
I tried something like this and also wanted to change the background color of the thead.
I did <thead className="bg-orange-500"> and nothing happens to its background. I couldn't find any information about the background color of the table on the doc.

There are two mistakes
You are using class selector . for a element type .
Change:
.tr:nth-child(even) {
background-color: #ccc;
}
to:
tr:nth-child(even) {
background-color: #ccc;
}
Spelling of odd has become od in your code.
For thead bg-color try the following code:
<table class="table-auto">
<thead class="bg-cyan-300">
<tr>
<th class="px-4 py-2">Item</th>
<th class="px-4 py-2">Value</th>
</tr>
</thead>
<tbody>
<tr>
<td class="px-4 py-2">Item 1</td>
<td class="px-4 py-2">Value 1</td>
</tr>
<tr>
<td class="px-4 py-2">Item 2</td>
<td class="px-4 py-2">Value 2</td>
</tr>
<tr>
<td class="px-4 py-2">Item 3</td>
<td class="px-4 py-2">Value 3</td>
</tr>
<tr>
<td class="px-4 py-2">Item 4</td>
<td class="px-4 py-2">Value 4</td>
</tr>
</tbody>
</table>
<style>
tbody tr:nth-child(even) {
background-color: #ccc;
}
tbody tr:nth-child(odd) {
background-color: #ffec20;
}
</style>
Output:

CSS vertical-align, how can I remove the little spacing below the text?

I have this code. Despite of being inside a td, and having specified this CSS:

border: 1px solid black;

.day--hole {
color: lightgray;

There's a visible gap between the position where the text should be centered and the current position of the text. It looks "upper" than it should and not totally centered. Why does this happen and how can I solve it without recurring to change the HTML or use flexbox?

That's because these numbers technically are text, and text - when using letters - has letters like g, j, p etc. which extend below the baseline. That's part of the line-height, and the vertical centering centers that line-height, regardless if there are letters like g, j, p in the text or not. So it looks a bit vertically offset as you describe it.
To compensate that, you could apply a vertical offset, as I did it in the first and last row of this snippet, using a wrapper for the numbers and applying position: relative and transform: translateY(1px); (or any value you like) to it:
.day {
text-align: right;
padding: 5px;
vertical-align: middle;
border: 1px solid black;
}
.day--hole {
color: lightgray;
}
.day--today {
background: pink;
}
.offset {
position: relative;
transform: translateY(1px);
}
<table>
<tbody>

As an example I made the height higher than needed. But give the example below a try. The height and line-height should be equal to center the text.
let height = document.getElementById('height');
let days = Array.from( document.querySelectorAll('.day') );
height.addEventListener('input', () => {
days.forEach( day => {
day.style.setProperty( '--height', `${height.value}px` );
});
});
.day {
text-align: right;
padding: 5px;
height: var(--height);
line-height: var(--height);
border: 1px solid black;
}
.day--hole {
color: lightgray;
}
.day--today {
background: pink;
}
:root {
--height: 40px;
}
<form>
<label for="height">Height (play with it to say that the text remains centered)</label>
<input type="number" id="height" min="1" value="40">

Aligning html tables to get vertical line same for both

Hello I have these following tables for which I want same vertical line. please check my code here link I have two vertical tables, I want same vertical line of alignment for both the tables so that The line between two tables appears same though the tables are different.
Here is what I want
Here is what I am getting if I add text to th .
please tell me how can I make it better.
table,
th,
td {
border: 1px solid black;
}
<table style="width:100%" cellpadding="10px" cellspacing="1px" padding="20px">
<tr>
<th>Month</th>
<td>Savings</td>
</tr>
<tr>
<th>January</th>
<td>$100</td>
</tr>
<tr>
<th>February</th>
<td>$80</td>
</tr>
</table>
<table style="width:100%">
<tr>
<th>Monthasnsandf</th>
<td>Savings</td>
</tr>
<tr>
<th>Januarydfsadfas</th>
<td>$100</td>
</tr>
<tr>
<th>Februarydfsadfsafa</th>
<td>$80</td>
</tr>
</table>

You could simply specify the width for the th and td elements, say 50%.
table, th, td {
border: 1px solid black;
}
table th, table td {
width: 50%;
}
table th {
text-align: left;
}
<table style="width:100%" cellpadding="10px" cellspacing="1px" padding="20px">
<tr>
<th>Month</th>
<td>Savings</td>
</tr>
<tr>
<th>January</th>
<td >$100</td>
</tr>
<tr>
<th>February</th>
<td >$80</td>
</tr>
</table>
<table style="width:100%" cellpadding="10px" cellspacing="1px" padding="20px">
<tr>
<th>Monthasnsandf</th>
<td>Savings</td>
</tr>
<tr>
<th>Januarydfsadfas</th>
<td >$100</td>
</tr>
<tr>
<th>Februarydfsadfsafa</th>
<td >$80</td>
</tr>
</table>

what I did is put the two tables in another table which has 2 rows to perfectly match vertical alignment
table, th, td {
border: 1px solid black;
}
table th, table td {
width: 50%;
}
<table>
<tr>
<td>
<table style="width:100%">
<tr>
<th>Month</th>
<td>Savings</td>
</tr>
<tr>
<th>January</th>
<td >$100</td>
</tr>
<tr>
<th>February</th>
<td >$80</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<table style="width:100%">
<tr>
<th>Monthasnsandf</th>
<td>Savings</td>
</tr>
<tr>
<th>Januarydfsadfas</th>
<td >$100</td>
</tr>
<tr>
<th>Februarydfsadfsafa</th>
<td >$80</td>
</tr>
</table>
</td>
</tr>
</table>
I assume this is what you expect!

Conditionally change color of angularjs element?

Im still pretty new to AngularJS. Im trying to change the color of the table element so that its yellow if the user voted on this choice.
<div ng-show="poll.userVoted">
<table class="result-table">
<tr ng-repeat="choice in poll.choices">
<td>{{choice.text}}</td>
<td>
<table ng-if="choice.text == poll.userChoice.text" style="background-color: yellow; width: {{choice.votes.length/poll.totalVotes*100}}%; text-align: right">
<tr>
<td>{{choice.votes.length}}</td>
</tr>
</table>
<table ng-if="choice.text != poll.userChoice.text" style="background-color: lightblue; width: {{choice.votes.length/poll.totalVotes*100}}%; text-align: right">
<tr>
<td>{{choice.votes.length}}</td>
</tr>
</table>
</td>
</tr>
</table>

This is done by using ng-class.
Use ng-class on your td like this:
<td ng-class="{yellowstyle: choice.text==poll.userChoice.text}">...</td>
that will put the css class yellowstyle on the item when your condition is true.
And in your example:
<table class="result-table">
<tr ng-repeat="choice in poll.choices">
<td>{{choice.text}}</td>
<td>
<table style="width: {{choice.votes.length/poll.totalVotes*100}}%; text-align: right">
<tr>
<td ng-class="{yellowstyle: choice.text==poll.userChoice.text, lightbluestyle: choice.text!=poll.userChoice.text}">{{choice.votes.length}}</td>
</tr>
</table>
</td>
</tr>
</table>
with a style.css file that has:
.yellowstyle {background-color: yellow;}
.lightbluestyle {background-color: lightblue;}

How to make fixed header table inside scrollable div?

I want to make header of my table fixed. Table is present inside the scrollable div. Below is my code.
<div id="table-wrapper">
<div id="table-scroll">
<table bgcolor="white" border="0" cellpadding="0" cellspacing="0" id="header-fixed" width="100%" overflow="scroll" class="scrollTable">
<thead>
<tr>
<th>Order ID</th>
<th>Order Date</th>
<th>Status</th>
<th>Vol Number</th>
<th>Bonus Paid</th>
<th>Reason for no Bonus</th>
</tr>
</thead>
<tbody>
<tr>
<td><%=snd.getOrderId()%></td>
<td><%=snd.getDateCaptured()%></td>
<td><%=snd.getOrderStatus()%></td>
<td>Data Not Available</td>
<td>Data Not Available</td>
<td>Data Not Available</td>
</tr>
</tbody>
</table>
</div>
</div>
Below is my CSS, which I am using for the above div:
#table-wrapper {
position:relative;
}
#table-scroll {
height:250px;
overflow:auto;
margin-top:20px;
}
#table-wrapper table {
width:100%;
}
#table-wrapper table * {
background:white;
color:black;
}
#table-wrapper table thead th .text {
position:absolute;
top:-20px;
z-index:2;
height:20px;
width:35%;
border:1px solid red;
}

How about doing something like this? I've made it from scratch...
What I've done is used 2 tables, one for header, which will be static always, and the other table renders cells, which I've wrapped using a div element with a fixed height, and to enable scroll, am using overflow-y: auto;
Also make sure you use table-layout: fixed; with fixed width td elements so that your table doesn't break when a string without white space is used, so inorder to break that string am using word-wrap: break-word;
Demo
.wrap {
width: 352px;
}
.wrap table {
width: 300px;
table-layout: fixed;
}
table tr td {
padding: 5px;
border: 1px solid #eee;
width: 100px;
word-wrap: break-word;
}
table.head tr td {
background: #eee;
}
.inner_table {
height: 100px;
overflow-y: auto;
}
<div class="wrap">
<table class="head">
<tr>
<td>Head 1</td>
<td>Head 1</td>
<td>Head 1</td>
</tr>
</table>
<div class="inner_table">
<table>
<tr>
<td>Body 1</td>
<td>Body 1</td>
<td>Body 1</td>
</tr>
<!-- Some more tr's -->
</table>
</div>
</div>

Using position: sticky on th will do the trick.
Note: if you use position: sticky on thead or tr, it won't work.
https://jsfiddle.net/hrg3tmxj/

Some of these answers seem unnecessarily complex. Make your tbody:
display: block; height: 300px; overflow-y: auto
Then manually set the widths of each column so that the thead and tbody columns are the same width. Setting the table's style="table-layout: fixed" may also be necessary.

None of the other examples provided worked in my case - e.g. header would not match table body content when scrolling. I found a much simpler and clean way, allowing you to setup the table the normal way, and without too much code.
Example:
.table-wrapper{
overflow-y: scroll;
height: 100px;
}
.table-wrapper th{
position: sticky;
top: 0;
background-color: #FFF;
}
<div class="table-wrapper">
<table>

I needed the same and this solution worked the most simple and straightforward way:
http://www.farinspace.com/jquery-scrollable-table-plugin/
I just give an id to the table I want to scroll and put one line in Javascript. That's it!
By the way, first I also thought I want to use a scrollable div, but it is not necessary at all. You can use a div and put it into it, but this solution does just what we need: scrolls the table.

This is my "crutches" solution by using html and css.
There used 2 tables and fixed width of tables and table cell`s

A Fiddle would have been more helpful nevertheless from what I understand, I guess what you need is persistent headers, look into this
http://css-tricks.com/persistent-headers/

This code works form me. Include the jquery.js file.

$(headerRow).wrap(headerDiv);
$("#"+headerDivId).insertBefore("#"+contentDivId);
/*End : Place header table inside <DIV> and place this <DIV> before content table*/
fixColumnWidths(headerDivId,contentDivId);
}
function fixColumnWidths(headerDivId,contentDivId){

use StickyTableHeaders.js for this.
Header was transparent . so try to add this css .
thead {
border-top: none;
border-bottom: none;
background-color: #FFF;
}

I know this question is old, but if anyone have this same issue, an easy way without having to write lots of CSS, just wrap your <table> with <div> and your <div> should have a style with overflow-y: auto; and some height.
As below example:
<div style="overflow-y: auto; height: 400px;">
<table>...</table>
</div>
Add a style to the thead as below:
thead {
position: sticky;
top: 0;z-index: 2;
}
