On this page I"ve been working on forever, I have this column headed "Bid x Ask": http://www.sellmycalls.com/so-bg-pos.png
in each of whose cell backgrounds there is supposed to be a bar chart that conveys the ratio of the numbers in the cell to each other.
So in each cell I have a background-color: gray; and a background-image:all-white;. I can't properly position the (plenty big enough) image on the gray background. In fact, in its current incarnation, the image doesn't show up at all.
How can I properly set the background-position of the image? The top <td> in the column is styled this way:
<td class="main_td bxa bxa_val"
style="background-color: #ecf1ef;
background-image:url('http://www.sellmycalls.com/pics/cell/bxa-white.png');
background-repeat:repeat-x repeat-y;
background-origin: 0px 0px;
background-attachment:fixed;
background-position:53px 0px;
-moz-background-position:53px 0px;
-webkit-background-position:53px 0px;
-khtml-background-position:53px 0px;
-o-user-background-position:53px 0px;">
<div> 543 x 470</div></td>
Thanks so much for your help!
Your image is 49x1px which I think is showing, however, with Firebug your TD shows a style of background-repeat:repeat-x; X not Y as you show in your example code snippet above.
UPDATE:
Try
style="background-color:#ecf1ef;
background-image:url('http://www.sellmycalls.com/pics/cell/bxa-white.png');
background-position:50px 0px;
background-repeat:repeat-y;"
you cannot adjust the dimensions of the image so (1) always make the image at least as wide as the TD itself (i.e. wider than 49px) and always use the background-image as the right hand side bar and the background-color for the left side bar. I hope this is all clear
It seems your image's path is incorrect. However the div child of each cell has a background-color rule, so this color cover any background of <td>

I searched a lot, but every solution was to include some constant CSS class names into the page, and use the Column's ClassNameGenerator to set the proper classname on the cell/row.
Now this might be a good solution when the developer can decide on formatting a cell, however when a user can decide (especially with a script written as cell renderer) how a cell will look like, it is not possible to use the ClassNameGenerator.
So question is, how can I format the cell/row background programmatically, not using any CSS? I can provide custom component as cell value. So it's fine to render a label with icon, or just icon, or a checkbox, however coloring this rendered component is not enough, since this is smaller than the cell itself, making it look really ugly. I need to access the root element of the cell, and color it using getStyle().set("background", "xxxx"). How to achieve this?
Thanks!
You can use a TemplateRenderer.
For example:
Grid<Person> grid = new Grid<>();
grid.setItems(people);
grid.addColumn(TemplateRenderer
.<Person>of("<b>[[item.name]]</b>")
.withProperty("name", Person::getName)
).setHeader("Name");

OK, finally I solved. I use a template renderer with a proper template structure. I modified the cell style in a way, that my renderer DIV fills the entire cell (removed any padding/margin from the original cells)
<dom-module id="grid-style" theme-for="vaadin-grid">
<template>
<style>
[part~='cell'] ::slotted(vaadin-grid-cell-content) {
padding: 0px;
height: 100%;
display: flex;
align-items: center;
justify-content: center;
--cellopa: 255;
}
[part~='cell'][aria-selected~="true"] ::slotted(vaadin-grid-cell-content) {
--cellopa: 0;
}
</style>
</template>
</dom-module>
I also added some simple CSS declarations to one of the main CSS:
vaadin-grid-tree-toggle flow-component-renderer {
width: 100%;
height: 100%;
}
vaadin-grid-cell-content flow-component-renderer {
width: 100%;
height: 100%;
flex-grow: 1;
}
This way the rendered DIV fills the whole cell and I can color it's background.
Now the problem comes with the selection, since the selection is not visible any more. For this you find the --cellopa variable set to 255 normally and set to 0 for selected cells.
Now when I define a background-color on the div, I use rgba and I set the alpha to the var(--cellopa) variable, like this for example rgba(255, 0, 0, var(--cellopa))
Now when the row is not selected, the cellopa is 255, so the background is visible, when I select the row the cellopa is set to 0, so the background of the DIV gets transparent, and the row selection color on the row is visible. This is super fast, and changing the selection does not cause any glitch, and also the previous coloring state is restored properly.
I also managed to get around with the treegrid and managed to color even the hierarchy column fully using a special template for the hierarchy column with some padding taking the level into account.
I am trying to position the control nav in flexslider 2 (the dots for each slide). Default is text-align:center. If you change to the left it positions to the left no problem. If you change to right then while it positions to the right it also shows text numbers of each slide over each dot.
How can I position this to the right WITHOUT the text numbers showing up? Furthermore, why are they showing up when aligned to the right?
You can see this happen out of the box in its default state by just changing the value to the below.
/* Control Nav */
.flex-control-nav {width: 100%; position: absolute; bottom: 0px; text-align: right;}
I thought that changing the -9999px to a positive had worked for me, until I realized that it just pushed the text way off the screen. But you could still scroll to it. My fix, leave the text-indent at -9999px; and add
color: rgba(0, 0, 0, 0); .
The last 0 in this controls the alpha, and with it at 0, that makes the numbers completely invisible.
removing width allows positioning without the number issue
I had problems with this, removing the width doesn't work. Here is a solution that does work:
.flex-control-nav {
text-align: right;
}
.flex-control-paging li a {
text-indent: 9999px;
}
When aligning the control nav to the right, you need to change the text indent from negative -9999px to a positive 9999px.
Use this code to adjust the positioning without the numbers.
/* Control Nav */
.flex-control-nav {position: absolute; bottom: 25px; right: 20px;}
Im trying to set a vertical carousel with AnythingSlider. But, I need to set a fix width for UL, and the script dont allow this. Is that possible?
Here is my code: http://jsfiddle.net/ycUB6/5230/
But the list stay with a blank space ;/
Anyone could help me?
AnythingSlider isn't, at this time, set up to allow multiple vertical slides. So, you will see some blank space below the last slide until it reaches the top.
To fix your demo, change this bit of css (updated demo):
ul#slider img {
width: 300px;
height: 100px;
list-style: none;
}

What I am trying to accomplish is to hide the content when it is outside of the background area (1280x800). I like the way the backgrounds are coming in when you scroll to a new section, but I want to hide the content until it gets into that 1280x800 viewport? Any suggestions on how I can accomplish this?
Bonus...It would be great if I could also hide the content under the top navigation once it scrolled up under it as well. A guy can dream. :)
Thanks!
For the first part you can add another div and target with css something like this:
.viewport {
width: 1280px;
height: 100%;
position: fixed;
top: 0;
left: 50%;
margin-left: -640px;
background: black;
clip: rect(800px, 1280px, auto, auto);
}
Basically, set the background to the same color as the page background and use clip to only display the portion of the div that sits below your desired viewport area hiding the content outside the viewport area.
If you add content to the footer later you may need to tweak some z-index settings to make sure it sits on top of the viewport div.
I'm building a Magento shop for a client, I uploaded some test images for the products but they seem to have a black background whenever I mouse over using chrome. Does anyone understand why? I don't see any problems with css so it has to be the images themselves.
URL: (I'm talking about those images below 'New products' and 'featured')

I made those using photoshop and the png-24 save-for-web option (http://bit.ly/zGXTAo). Been doing that for years and this is actually the first time happening.
The problem is in your css. Look at the background image:
a.product-image {
margin-bottom: 10px;
width: 182px;
height: 239px;
border: 1px solid #2F3238;
background: url("/images/thumb_bg.png") 50% top no-repeat;
display: block;
border-image: initial;
If you right click on the images, and view in new tab you will see that they are transparent. Your background is dark, so the image picks that up.
