So I'm designing the website for my dad's company and I'm trying to get rid of the whitespace above the header on the page. I tried making the margins 0 and paddings 0 but nothing is changing. Here is my code and a link to the website:
header {
font-size: 20px;
position: relative;
background-color: #DDDDDD;
height: 150px;
}
The problem is the the w3-sidebar-class you are using inside the page. It sets the top margin to a negative value. In order to analys these kind of problems, I suggest you start from a black html page and add new elements to it step by step. Then you can see which changes have which effect.

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 have trouble finding the correct css code for changing the looks of a toast in Ionic 4.
In Ionic 3 you could use padding in css to change the look of a toast.
--min-height changes the height but it also places the message text to the top of the toast which I don't want.
I have this in my global.scss:
ion-toast.toast-mess {
text-align: center;
color: var(--ion-color-light);
font-size: 30px;
--border-radius: 30px;
padding: 50px;}
In the above code, padding is not taken into account, all other parameters work fine.
The default .toast-message says padding is available because it contains some default values.
How can I use padding again in custom css code, or something similar ?
Thanks
have you tried with
--padding-end
--padding-start
--padding-top
--padding-bottom
I've got an inline-block element that contains a very long word. When I resize the viewport until I reach the breakpoint of the text wrapping to the next line, I get a substantial amount of space. However, I would like the inline-block element to wrap immediately to the width of its contents.
I found it hard to explain exactly what's going on, so below an animated gif to illustrate my issue:
Upon resizing the viewport:
To be clear, the image above is me continuously resizing the viewport.
Does anybody know a way to achieve what I'd like? Even with CSS hyphenation the white-space still remains (which I don't want).
JSFiddle. Resize the frames to see what I mean.
div {
display: inline-block;
background-color: black;
color: white;
padding: 5px;
}
The inline-block indeed extends on resizing as your animation shows, so that it keeps place for the long word to go into that space again.
One simple solution would be to add text-align: justify, but I'm afraid it may not exactly be what you want (see demo).
Another one would be the use of media queries, as #Parody suggested, but you would have to know the dimentions of the containing div, and that would not be very scalable as you mentionned.
The word-break: break-all suggested by #yugi also works but causes the words to to collapse letter by letter, regardless of their length.
The only way to achieve the exact behavior is (as far as I know) to use javascript. For example, you would have to wrap your text into a span element inside the div, and then add something like this :
var paddingLeft = parseInt($('#foo').css('padding-left')),
paddingRight = parseInt($('#foo').css('padding-left')),
paddingTop = parseInt($('#foo').css('padding-top')),
paddingBottom = parseInt($('#foo').css('padding-Bottom')),
cloned = $('#foo span').clone(),
cloned_wrap = document.createElement('div');
$(cloned_wrap).css({
paddingLeft : paddingLeft,
paddingRight : paddingRight,
display : 'inline-block',
visibility: 'hidden',
float: 'left',
});
$(cloned_wrap).insertAfter('#foo');
cloned.appendTo(cloned_wrap);
$(window).on('resize', function(){
$('#foo').css('width', cloned.width() + 1);
$(cloned_wrap).css('margin-top',- $('#foo').height() - paddingTop - paddingBottom);
}).resize();
Please see the jsfiddle working demo. (← edited many times)
That's quite a lot of code, but it works ; )
(PS : I assumed jquery was available, if not, quite the same is achievable in pure JS)
I don't think this is possible only with CSS for the one element. The reason for your behavior is that the width of the element is still 100% of its container. The only way I could think to accomplish this is by doing something a little bit "creative"...try setting the style to inline so you get the shrink-wrap behavior, but to get around the background color issue, also put it in a container that shares the same background. That should work.
If im understanding you correctly you could use the #media type to decide what css to use depending on the width of the screen
here is an example of what i mean
#media(min-width:0px) and (max-width:200px){
div {
display: block;
background-color: black;
color: white;
padding: 5px;
}
}
#media (min-width:200px){
div {
display: inline-block;
background-color: black;
color: white;
padding: 5px;
}
}
I am still very appreciative of #lapin's answer (which I accepted and awarded bounty to), I found out after the fact that it didn't quite work on multiple elements next to each other (that has nothing to do with #lapin, I just didn't mention it in my original question as I thought it would be irrelevant information).
Anyway, I've come up with the following that works for me (assuming the elements it should be applied to are .title and .subtitle):
$('.title, .subtitle').each(function(i, el) {
var el = $(el),
inner = $(document.createElement('span')),
bar = $(document.createElement('span'));
inner.addClass('inner');
bar.addClass('bar');
el.wrapInner(inner)
.append(bar)
.css({
backgroundColor: 'transparent'
});
});
function shrinkWrap() {
$('.title, .subtitle').each(function(i, el) {
var el = $(el),
inner = $('.inner', el),
bar = $('.bar', el),
innerWidth = inner.width();
bar.css({
bottom: 0,
width: innerWidth + parseFloat(el.css('paddingLeft')) + parseFloat(el.css('paddingRight'))
});
});
}
shrinkWrap();
$(window).on('resize', function() {
shrinkWrap();
});
Basically what I do is:
put the text in an inner wrap element
create an additional absolutely-positioned background element
get the width of the inline inner wrap element
apply said width to the background element (plus padding and whatnot)
The CSS:
.title, .subtitle {
position: relative;
z-index: 500;
display: table;
padding-left: 10px;
margin-right: 10px;
background-color: red;
}
.title .bar, .subtitle .bar {
position: absolute;
top: 0;
left: 0;
bottom: 0;
z-index: -10;
background-color: red;
}
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;
}
