Strange border with custom box-shadow and focus indicator - html

I made sample with two number inputs with custom outline and box-shadow.
In Google Chrome I see strange black-gray border after focus on bottom input element.
For this input I use
.shadowBox:focus {
outline: 1px black dotted !important;
box-shadow: 1px 1px grey;
}
If I set box-shadow: none this strange border doesn`t appear. What I do wrong?
EDITED. Why this "strange border" appears on 'focus' if I use box-shadow? This border exists only in Google Chrome, but not in Mozilla Firefox.

If you want to have both, the dotted outline And border solid you can have this instead:
.shadowBox:focus {
outline: 1px dotted black;
border: 2px black solid;
}

outline property of input control doesn't respect border-radius

I have an input field with border-radius and when it's in focus the outline appears but it has rectangular property. I'm using Chrome. Is this a bug? I don't want to remove outline I just want it to respect border-radius.
No unfortunately it is not possible to keep an outline that is respecting the border-radius in all browsers.
Instead it would be much easier to remove the outline with outline: 0; and adding a custom border or box-shadow with CSS on focus.
Example:
input[type="text"] {
outline: none;
}
input[type="text"]:focus {
box-shadow: 0 0 3px blue;
}
(http://jsfiddle.net/3cggR/)
input[type=text]:focus{
box-shadow: 0px 0px 2px 1px orange;
outline:none;
}

Control the two colors of an inset border?

I'm trying to see if there's a way to change the two colors of the inset border in CSS
As you know, the inset style creates a border on an element that creates the illusion that that it has an embedded border. It achieves this by making the bottom and right border the color you selected, and changes the color of the top and left border a slightly darker shade.
Does anyone know of a way where you can control how dark, or maybe even different color the alternate shade would be?
#myElement{
border: inset 1px white;
}
Thanks.
I don't think you can control it the way I mentioned, but for sure you can control the individual color of each border:
#myElement{
border-style: solid;
border-width: 1px;
border-top-color: black;
border-left-color: black;
border-right-color: white;
border-bottom-color: white;
}
If you want to use the same color for all sides of the inset border, try this, which I used and worked fine.
border-style: solid inset solid solid;

remove inner shadow of text input

So I have a text input, im using html5, on chrome, and I want to change the look of a text input, I've removed the outline on focus (orange on chrome), I set the background to a light color #f1f1f1 but now there is like a thicker border on the top and left sides, like it's meant to look pushed in, when there is no change in background color this doesn't happen. How do I remove it? Sorry I can't provide a picture, on a mobile device.
It happens on chrome, ie, and Firefox, can't test any others.
border-style:solid; will override the inset style. Which is what you asked.
border:none will remove the border all together.
border-width:1px will set it up to be kind of like before the background change.
border:1px solid #cccccc is more specific and applies all three, width, style and color.
Example: https://jsbin.com/quleh/2/edit?html,output
This is the solution for mobile safari:
appearance: none;
-moz-appearance: none;
-webkit-appearance: none;
as per https://developer.mozilla.org/en-US/docs/Web/CSS/appearance
and as suggested here: Remove textarea inner shadow on Mobile Safari (iPhone)
None of the solution are working currently.
Here is my solution. You can add prefixes.
box-shadow: inset 0px 0px 0px 0px red;
Add border: none or border: 0 to remove border at all, or border: 1px solid #ccc to make border thin and flat.
To remove ghost padding in Firefox, you can use ::-moz-focus-inner:
::-moz-focus-inner {
border: 0;
padding: 0;
}
See live demo.
Set border: 1px solid black to make all sides equals and remove any kind of custom border (other than solid).
Also, set box-shadow: none to remove any inset shadow applied to it.
Try this
outline: none;
live demo https://codepen.io/wenpingguo/pen/KQgbXq
All browsers, including Safari (+ mobile):
input[type=text] {
/* Remove */
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
/* Optional */
border: solid;
box-shadow: none;
/*etc.*/
}
I'm working on firefox. and I was having the same issue, input type text are auto defined something looks like boxshadow inset, but it's not.
the you want to change is border... just setting border:0; and you're done.
here is a small snippet that might be cool to try out:
input {
border-radius: 10px;
border-color: violet;
border-style: solid;
}
note that: border-style removes the inner shadow.
input {
border-radius: 10px;
border-color: violet;
border-style: solid;
}
<input type="text"/>

How to change/remove form border color on selection?(Chrome)

So I'm using
-webkit-border-radius: 10px;
for a text entry field right now, but the problem is that once the field is selected, there is a border without the border radius modified.
So my question is does anyone know how to modify this?
I don't know if you can set the outline to have a radius like the border but you can remove it with
outline:none;
Besides the outline you may also use
-webkit-appearance: none;
No webkit equivalent to -moz-outline-radius at the moment
While there's no (so far as I'm aware) cross-browser implementation of outline-radius, or even a vendor-prefixed implementation other than the -moz- variant, you could perhaps emulate it with an inset box-shadow:
.elementClass {
padding: 0.2em;
outline: none;
border: 1px solid #000; /* in Chromium 18/Ubuntu 11.04 setting
the border is required for the outline
to be applied, this may not be true elsewhere */
border-radius: 0.4em;
}
.elementClass:focus,
.elementClass:active {
box-shadow: inset 0 0 1px 2px #f90;
}​

HTML: Sub-pixel border

Is it possible to have a border that is thinner than 1px and works in IE6+ and is not an image and renders properly visually?
Thank you.
I think you could define the width of a border using units like em which would come out to less than 1px, and it would be valid. However, like Will Martin said, for display purposes it would just round it up or down to a whole pixel.
Edit: I have overseen the IE6 restriction, but I leave the answer here for others ...
Its possible with transform:scale(0.5) and put a border element with border:1px; inside. So you get a half pixel border, that (although tricked and browser dependend) is displayed on screen. But I use that trick for printing.
sure, you have to adapt the content of the element, or play with position
.outer {
border:1px solid green;
}
.halfpix {
-ms-transform-origin: 0 0;
-webkit-transform-origin: 0 0;
transform-origin: 0 0;
-ms-transform:scale(0.5);
-webkit-transform:scale(0.5);
transform:scale(0.5);
width:200px;
height:100px;
border:1px solid black;
}
<div class="outer">
<div class="halfpix">
</div>
zoom browser window if your browser does not display
</div>
I don't know about IE8-10 (IE6-7 definitily no go) , but in Chrome and FF I get the thinnest border with box-shadow. Works best to get a 1px <hr> instead of the autorendered 2px, but can be used on a border as well.
The thin border on the HR is more prominent in FF than Chrome, but also Chrome renders 2px.
http://jsfiddle.net/GijsjanB/3G28N/
.thin {
border: 1px solid white;
box-shadow: 0 0 1px black;
}
No. You can't show a size smaller than one pixel because pixels are the basic unit of the monitor. And anyway, no browser I know of allows you to specify sub-pixel widths. They just get rounded up to 1px or down to 0px.
Although this isn't (currently) possible in any version of IE or Edge, on the latest versions of Firefox and Chrome you can now use border width values less than 1px.
.borderTest {
box-sizing: border-box;
display: block;
margin: 0.5em;
padding: 0.5em;
width: calc( 100% - 1em );
}
.borderTest:nth-child(1){
border: 1px solid #000
}
.borderTest:nth-child(2){
border: 0.75px solid #000
}
.borderTest:nth-child(3){
border: 0.5px solid #000
}
.borderTest:nth-child(4){
border: 0.25px solid #000
}
<div class="borderTest">1px</div>
<div class="borderTest">0.75px</div>
<div class="borderTest">0.5px</div>
<div class="borderTest">0.25px</div>
This outputs the following on a UHD screen:
you can transform the line like that:
.thin{ -ms-transform:scale(1, 0.5); -webkit-transform:scale(1, 0.5); transform:scale(1, 0.5);}
or, if the line is vertical
.thin{ -ms-transform:scale(0.5, 1); -webkit-transform:scale(0.5, 1); transform:scale(0.5, 1);}
To render native 1px borders on high DPI/#2x/retina displays, there are a couple of tricks.
On Firefox and Safari (macOS and iOS), use a 0.5px border:
/* Fallback: Most browsers now render 0.5px as 1px though */
.el {
border: 1px solid red;
}
.retina .el {
border: 0.5px solid red;
}
On Chrome, use a box-shadow with a 0.5px spread:
.retina-chrome .el {
box-shadow: 0 0 0 0.5px red;
}
Use JS to add a class to the HTML element to only target #2x+ displays.
if (window.devicePixelRatio >= 2) {
document.documentElement.classList.add(
window.chrome ? 'retina-chrome' : 'retina'
);
}
For #1x displays, use a slightly lighter color 1px border.
Try adding a box-shadow
box-shadow: 0px 0px 1px 0px black;
Edit: Chrome 98 (February 1, 2022) added direct support for border-width values less than 1px.
As of mid 2020, current versions of Safari and Firefox both support border-width: .5px.
On the other hand, Chrome will treat it as 1px.
You can detect whether the browser supports it with something like:
var el = document.createElement('div');
el.style.position = 'fixed';
el.style.borderTop = '.5px solid';
document.body.appendChild(el);
var hasSubpixelBorder = el.getBoundingRect().height < 1;
document.body.removeChild(el);
Make sure this is called after document.body is created if you are doing it at startup.
If this is not supported (e.g. Chrome) you can add a class to document.body or some parent element to cause descendants to take on a different border style:
#media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 2dppx) {
.noSubpixelBorder .border-top {
border-top-width: 0;
background-image: linear-gradient(180deg, var(--mycolor) 0, var(--mycolor) .5px, transparent 0);
}
}
#media (-webkit-min-device-pixel-ratio: 3) and (-webkit-max-device-pixel-ratio: 3.5), (min-resolution: 3dppx) and (max-resolution: 3.5dppx) {
.noSubpixelBorder .border-top {
background-image: linear-gradient(180deg, var(--mycolor) 0, var(--mycolor) .333333px, transparent 0);
}
}
You can use multiple linear gradients to achieve borders on multiple sides. This takes over background-image so if you are using it for something else you will need to find another way (there are a couple others).
This is not particularly clean, but it seems to consistently work.
If you wanted to be super crafty, you could support oddball pixel ratios by computing the stylesheet on the fly.
0.1em displays border smaller then 1px try dotted border with 1px and compare it with 0.1em
Maybe late post ,
<table>
<tr>
<td style="border:1px ridge">
....text....
</td>
</tr>
<table>
using ridge(alternative) for thin border //IMO
For me this worked:
I needed a white border with less than 1px
So I added some opacity to the border color and it started to look thiner than 1px
like this:border-top: 1px solid #ffffff26;
try
border-top: 1px solid #c9d6df;
smaller than
border: 1px solid #c9d6df;
You could use CSS border-image to set an SVG or other image as the border, and then you could make the image line as narrow as you would like. It may still be rendered on screen as 1px, but if you then print or save the webpage out, the true size will be kept.
With border you have a hard time to achieve thinner line!
If you want to have a horizontal line like me, you can do that with height instead of border:
Note: Maybe you need to zoom in to see the real difference between the two lines!
.normal {
height: 1px;
background-color: #8bacda;
}
.thinner {
height: 0.01em;
background-color: #8bacda;
}
<p>Normal Line</p>
<div class="normal"></div>
<p>Thinner Line</p>
<div class="thinner"></div>
