I am toggling the header visibility and when I hide it, I need it to be transparent and show the scrolling content.
I tried several ways but the header is not transparent. Please note it's hidden correctly but it left a white background instead. So I wanted to make it transparent:
$('.ui-header').hide().animate({opacity: 0.0});// Hide the header but its opacity doesn't get to 0
$(".ui-header").css("backgroundColor", "transparent");// No effect
How to make the header transparent so it will show the content underneath?
$(".ui-header").hide();
Should be sufficient. Hiding the element means not showing it, which is equivalent to setting the opacity of the element to zero.
When reading the documentation for the jQuery function .hide(), it clearly states that .hide() without any parameters is the equivalent to display: none; in CSS.
If you can't find the error with JS, I suggest giving display: none; to the ui-header class in CSS. If neither works we need more code to track down the error and give you a proper answer.
Edit: A JSFiddle demo available here.

I'm trying to figure out how to change the thick light blue border that appears while the mouse button is down when clicking on a pagination number. I have tried border-color on the a element but that doesn't do it.
ul.pagination a.page-link:active {
border-color: #f00;
}
Don't remove outlines (or their visual substitutes). They have an important purpose.
It's actually a box-shadow variable. But just restyle it. Don't remove it.
.page-link:focus {
box-shadow: var(--bs-pagination-focus-box-shadow);
}
You'll want to learn how to use your browser's document inspector to discover what CSS rule is styling an element. You can force states to find :active and :hover styles, for example.
I've got an app which leverages a WKWebView for most of the content. In a few screens we have buttons in a div which leverages position: fixed; so that they're always in the same place as a long form scrolls underneath. When the virtual keyboard is shown I add a class to the document body that can be used to adjust other things, for example, tweaking the bottom property on the div containing these buttons so they move above the keyboard.
So far, so good, they're always visible. The problem arises when the form is then scrolled, the buttons visibly move up with the rest of the page (which they shouldn't), but the browser actually acts as if they're still position where they're supposed to be. The screen shot shows where the browser believes the buttons are, and if you touch those areas then the buttons get activated.
I'm happy to chalk this up as a bug with WebKit or specifically WKWebView, but is there a known workaround for this so that they render in the correct place? I read that adding a translation to trigger hardware rendering could help, but it doesn't seem to have done the job here. I also read that changing the position to absolute could solve this issue, but for me it just results in them being rendered off screen somewhere altogether.
You can add fixed position to button wrapper
.btn-bar-fixed {
position: fixed;
bottom: 0px;
right: 0px;
}
I have recently started using Vaadin. I am stuck at one point. I can disable the scrollers. But the bars are visible when I resize the grid how can I hide the bars? You can see view attached image to get the issue.
In order to hide the scrollbar, you need to override some CSS. Steps to overriding CSS are:
Set your theme in the application
setTheme("yourThemeName")
Then in your Table you can use your own style
table.addStyleName("yourStyleName")
Now you have to define your own CSS style in
VAADIN/themes/yourThemeName/styles.css
#import "../reindeer/styles.css";
.v-table-mymodel .v-scrollable {
overflow: hidden;
}
Once you've done this, clear your browser's cache and refresh your page. You should not see your scroll bar.
I know about css sprites.. Now i want some examples of css sprites....
How did you manage to get css sprites work?
I usaully use the CSS background property. This property allows you to set a scroll argument of top and left as you can see in the example below. So the idea is to create one image with all states and simply position it based on the event like hover or other custom event in which you alter the elements CSS. I hope this helps.
.mySprite a
{
background: transparent url(/images/spriteButton.gif) no-repeat scroll 0 0
}
.mySprite a:hover
{
background: transparent url(/images/spriteButton.gif) no-repeat scroll 30 0
}

If you are using Firefox here is a simple way to get an idea of what a sprite is. Go to yahoo.com, right-click and View Page Info, click Media. Look for a file name having "sprite" in it.
This is one of the links:
http://d.yimg.com/a/i/ww/met/gsprite_071309.gif
You will see many background gradient images. You can use this file to play with. Now you have to adjust background position in your CSS depending on which background you want to use, like this:
background-image: url('http://d.yimg.com/a/i/ww/met/gsprite_071309.gif') left -30px repeat-x;
This should give you an idea of how to manage sprites.
If you are looking to create a CSS sprite - you can check out the site spriteme.org, which is very cool and shows you how to easily create a CSS sprite.
For a nice example you can check out this page:
http://www.programmerinterview.com/index.php/general-miscellaneous/css-sprite-example-and-tutorial/
Gives a good explanation and shows how the website owner uses a sprite.
I use them for button images. I use the top half of an image for the normal button state and the bottom half for the mouse-over state. That way the mouse over image is loaded when the page loads and there's no delay which just looks bad and slow. CSS code is here.

It has a great interactive example and everything you need to know about CSS Sprite.
As far as I use sifr.setup(); every h2, h1, and so on becomes invisible. But I don't want that.
I just want the "selectors" to provide a replacement and become invisible and replaced.
How can I prevent that?
I also have another problem where every font is blue and it never gets that color from anywhere.
Sounds like you've kept the original CSS, which hides those elements. Have a look at the CSS file and remove the original .sIFR-hasFlash h1 selectors.
Can you post an example for the color problem?
