How to create the dropdown arrow from Twitter's Bootstrap? - html

I've been checking/using Twitter Bootstrap for quite a while now. I like what they've done, but more than that, I like understanding what I do.
After inspecting the dropdown arrow with Chrome's inspector, it seems it is in fact a ↓ html entity. I've been trying to reproduce this but with no success. I'm getting an ugly arrow and not the simple triangle.
What are the minimum CSS properties to use in order to reproduce it?
PS: A link to a jsFiddle trying to reproduce it.

Here's a working example.
You don't need the extra ↓ in your HTML and the border-color was white, making it invisible on a white background to your very human eyes.

First avoid default browser styles. Then use your own. As an example:
select{
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
height: 60px;
border: 1px solid #ccc;
padding: 0 0 0 20px;
font-size: 18px;
font-weight: 300;
border-radius: 0;
color: #999;
letter-spacing: 1px;
background: url("../img/arrow#2x.png") calc(100% - 10px) 24px #fff no-repeat;
cursor: pointer;
}

Is there a way to style the blue focus ring on text links with CSS?

I'm having some issues trying to style the :focus state for text links in my SCSS design system, to ensure accessibility on keyboard navigation but also to make it look a bit nicer than the stock box outline.
I've managed to get it working cross-browser for text fields and buttons by using outline:none; and replacing it visually with box-shadow: 0 0 0 2px $color. I have to do this because Safari's focus outline doesn't follow border-radius.
Here's how it looks for form fields:
three text fields, the first of which has a custom focus state border
But for text, it still has the blue outline:
snippet of text with visited links, one has focus but still has a blue outline
html {
box-sizing: border-box;
font-size: 16px;
}
a {
color: #0000ff;
text-decoration: underline;
}
p {
color: #3b3b3b;
font-family: system-ui;
line-height: 1.5;
padding-left: 1rem;
padding-right: 1rem;
}
a:visited {
color: purple;
}
a:focus-visible {
text-decoration: none;
background-color: #0000ff;
color: white;
outline: 0;
box-shadow: 0 0 0 2px #0000ff;
border-radius: 2px;
}
a:visited:focus-visible {
text-decoration: none;
background-color: purple;
color: white;
outline: 0;
box-shadow: 0 0 0 2px purple;
border-radius: 2px;
}
<p>Here is some text. Here's one link. And here is some other text in between. And here is another link. Another link.</p>
Here's a CodePen demo.
As you can see, when you use tabs or keyboard navigation, when a visited link has :focus, it gets the correct background and text color, but still has a blue focus border, and I can't seem to get rid of it.
Using the Inspector, I can't see any other styles that are overriding it. It does follow the border-radius, so I'm just kind of confused as to where it's coming from.
CSS is supposed to let you stack basic selectors like :visited and :focus-visible, right?
For reference, this isn't exclusive to Safari, it happens in Chrome and Firefox as well, so it does seem to be CSS-related.

CSS property text-align being overridden by iOS Webkit for submit button

The following is my CSS code for a form's submit button:
.submit {
-webkit-appearance: none !important;
text-align: center !important;
border-radius: 0rem;
color: rgb(63, 42, 86);
display: inline-block;
float: right;
border: none;
font-size: 14px;
border-left: 0.05rem solid rgb(63, 42, 86);
width: 3.6rem;
height: 2.2rem;
line-height: 1.75rem;
transition: background-color 0.2s;
background-color: transparent;
}
After some initial formatting issues on iOS, I implemented -webkit-appearance: none which fixed most of the problems. But the "Submit" text for the Submit button is now right-aligned instead of centered on iOS, as shown in this image: http://ben-werner.com/screenshot/01.png
On the desktop version using chrome and safari however, the text displays centered as it should: http://ben-werner.com/screenshot/02.png
I don't think it is a specificity issue, as the !important declaration of text-align: center should prevent anything else in my CSS overriding it.
Does anyone have an idea what is happening on the iOS device that causes the Submit text to function differently? Any help is much appreciated, thanks!
CodePen Link: https://codepen.io/benwerner01/pen/BqErOE (Note: the html formats correctly on the CodePen site, but the same code running within safari or chrome on iOS breaks the button. I have hosted the code from CodePen at https://ben-werner.com , to demonstrate that on mobile it displays incorrectly)
Ok, I know what is happening now. You are giving your submit button a specific width and height that is affecting the text-align on iOS devices. Removed the width and height values and your text will align center on iOS devices. I would also use padding to give your button the desired width and height instead of those properties.
.submit#mc-embedded-subscribe {
border-radius: 0 !important;
-webkit-appearance: none !important;
color: rgb(63, 42, 86);
float: right;
border: none;
font-size: 14px;
border-left: 0.05rem solid rgb(63, 42, 86);
/* width: 3.6rem;
height: 2.2rem; */
text-align: center !important;
text-align: -moz-center !important;
text-align: -webkit-center !important;
line-height: 1.75rem;
transition: background-color 0.2s;
background-color: transparent;
margin: 0 auto;
}

Removing Safari input glow [duplicate]

I am wondering if its possible to remove the default blue and yellow glow when I click on a text input / text area using CSS?
Edit (11 years later): Don't do this unless you're going to provide a fallback to indicate which element is active. Otherwise, this harms accessibility as it essentially removes the indication showing which element in a document has focus. Imagine being a keyboard user and not really knowing what element you can interact with. Let accessibility trump aesthetics here.
textarea, select, input, button { outline: none; }
Although, it's been argued that keeping the glow/outline is actually beneficial for accessibility as it can help users see which Element is currently focused.
You can also use the pseudo-element ':focus' to only target the inputs when the user has them selected.
Demo: https://jsfiddle.net/JohnnyWalkerDesign/xm3zu0cf/
This effect can occur on non-input elements, too. I've found the following works as a more general solution
:focus {
outline-color: transparent;
outline-style: none;
}
Update: You may not have to use the :focus selector. If you have an element, say <div id="mydiv">stuff</div>, and you were getting the outer glow on this div element, just apply like normal:
#mydiv {
outline-color: transparent;
outline-style: none;
}
On textarea resizing in webkit based browsers:
Setting max-height and max-width on the textarea will not remove the visual resize handle. Try:
resize: none;
(and yes I agree with "try to avoid doing anything which breaks the user's expectation", but sometimes it does make sense, i.e. in the context of a web application)
To customize the look and feel of webkit form elements from scratch:
-webkit-appearance: none;
I experienced this on a div that had a click event and after 20 some searches I found this snippet that saved my day.
-webkit-tap-highlight-color: rgba(0,0,0,0);
This disables the default button highlighting in webkit mobile browsers
Carl W:
This effect can occur on non-input elements, too. I've found the following works as a more general solution
:focus {
outline-color: transparent;
outline-style: none;
}
I’ll explain this:
:focus means it styles the elements that are in focus. So we are styling the elements in focus.
outline-color: transparent; means that the blue glow is transparent.
outline-style: none; does the same thing.
This is the solution for people that do care about accessibility.
Please, don't use outline:none; for disabling the focus outline. You are killing accessibility of the web if you do this. There is a accessible way of doing this.
Check out this article that I've written to explain how to remove the border in an accessible way.
The idea in short is to only show the outline border when we detect a keyboard user. Once a user starts using his mouse we disable the outline. As a result you get the best of the two.
If you want to remove the glow from buttons in Bootstrap (which is not necessarily bad UX in my opinion), you'll need the following code:
.btn:focus, .btn:active:focus, .btn.active:focus{
outline-color: transparent;
outline-style: none;
}
This solution worked for me.
input:focus {
outline: none !important;
box-shadow: none !important;
}
some times it's happens buttons also then use below to remove the outerline
input:hover
input:active,
input:focus,
textarea:active,
textarea:hover,
textarea:focus,
button:focus,
button:active,
button:hover
{
outline:0px !important;
}
<select class="custom-select">
<option>option1</option>
<option>option2</option>
<option>option3</option>
<option>option4</option>
</select>
<style>
.custom-select {
display: inline-block;
border: 2px solid #bbb;
padding: 4px 3px 3px 5px;
margin: 0;
font: inherit;
outline:none; /* remove focus ring from Webkit */
line-height: 1.2;
background: #f8f8f8;
-webkit-appearance:none; /* remove the strong OSX influence from Webkit */
-webkit-border-radius: 6px;
-moz-border-radius: 6px;
border-radius: 6px;
}
/* for Webkit's CSS-only solution */
#media screen and (-webkit-min-device-pixel-ratio:0) {
.custom-select {
padding-right:30px;
}
}
/* Since we removed the default focus styles, we have to add our own */
.custom-select:focus {
-webkit-box-shadow: 0 0 3px 1px #c00;
-moz-box-shadow: 0 0 3px 1px #c00;
box-shadow: 0 0 3px 1px #c00;
}
/* Select arrow styling */
.custom-select:after {
content: "▼";
position: absolute;
top: 0;
right: 0;
bottom: 0;
font-size: 60%;
line-height: 30px;
padding: 0 7px;
background: #bbb;
color: white;
pointer-events:none;
-webkit-border-radius: 0 6px 6px 0;
-moz-border-radius: 0 6px 6px 0;
border-radius: 0 6px 6px 0;
}
</style>
I found it helpful to remove the outline on a "sliding door" type of input button, because the outline doesn't cover the right "cap" of the sliding door image making the focus state look a little wonky.
input.slidingdoorbutton:focus { outline: none;}
I just needed to remove this effect from my text input fields, and I couldn't get the other techniques to work quite right, but this is what works for me;
input[type="text"], input[type="text"]:focus{
outline: 0;
border:none;
box-shadow:none;
}
Tested in Firefox and in Chrome.
Sure! You can remove blue border also from all HTML elements using *
*{
outline-color: transparent;
outline-style: none;
}
And
*{
outline: none;
}

windows phone 8 highlight colors in input fields

in internet explorer 10 (mobile version), a selectbox () gets highlighted blue as soon as it gets focused, (it´s the blue of the whole Modern UI surface of the phone). the styles for the select tag:
border-radius: 5px 5px 5px 5px;
font-size: 14px;
height: 25px;
letter-spacing: -1px;
float: left;
font-weight: 400;
padding: 0 5px 0 5px;
-webkit-appearance: none;
-ms-user-select: none;
background-origin: content-box, content-box;
background-repeat: no-repeat, repeat;
background-size: 11px 6px, 1px 160px;
background-position: right center, 0 -1px;
background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABcAAAAMAQMAAACz9bS7AAAABlBMV…vQuZgJjsYojkBJQf75i4cGzcXt5HJQ/Djs7L5sApGeVNPJDzbGEbOb/85rAAAAAElFTkSuQmCC), url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAlgCAIAAADGR8ryAAACZ0lEQ…tDzV5P+JnOAzg9qR2Xlg+a8jAvtyK/P5fSI6Sf3c3NhwADAJ0Rj8qbukvYAAAAAElFTkSuQmCC);
border: 1px solid #CCCCCC;
I was hoping the "-ms-user-select: none" would fix it, but didnt.. Has anyone experience similar?
I've encountered a similar problem on WP7 an WP8, the solution is to move focus from select box to fake input on click event.
jQuery:
$('select').on('click', function() {
$('input.fakeInput').focus().blur()
})
CSS:
.fakeInput {
display: block;
width:0;
height:0;
top: -999rem;
position: absolute;
}
Note: do not forget to add this code only for mobile device, on desktop browsers it will work not as expected.
IE has its own CSS pseudo-element to deal with this highlight.
CSS:
select::-ms-value{ background-color: transparent; color: black; }
You may read more about this on this page.
it´s interesting but since I add this line to my style sheet, it keeps highlighting blue, but doesn´t stay that way after you select something from the selectbox.
Thought I add it as an answer if somebody comes back with the issue.
:focus{outline: none;}

How to normalize a button and an anchor with CSS?

Check out this code sample of a button and an anchor: http://jsbin.com/ecitex/2/edit
I'm trying to make them identical in all browsers. But differences remain, and different differences in every browser (tried Chrome, Safari, Firefox, IE8).
Which CSS normalizations am I missing?
Update:
Per suggested:
I added line-height: 50px (although my user agent's (Chrome's) default line-height for button elements is normal, and still it vertically centers text – how?!)
I added cursor: pointer to normalize mouse cursors.
http://jsbin.com/ecitex/11/edit
So, now check out the result in Firefox: notice the padding on the button?
Then check out the result in IE8: whoa, notice how the two are completely and utterly different?!
Update 2:
It seems that IE's problems are known and non-resolvable: http://www.quirksmode.org/css/tests/mozie_button2.html
I haven't found anything on Firefox's padding though. (The quirksmode article mentions an issue with Mozilla, but that's a different issue.)
Update 3:
Awesome, we fixed the Firefox issue: http://jsbin.com/ecitex/15/edit
Okay, so far every single answer has been providing part of the solution so there's not really one single best answer. I'll grant the best answer to the person that either:
Explains why we have to specify a line-height: 50px to vertically center text in an a, while a button has vertically centered text with a mere line-height: normal.
Provides a solution for the IE issue.
You can remove that extra padding in Firefox by using:
button::-moz-focus-inner {
border: 0;
padding: 0;
}
Here's a good explanation from Eric Meyer about line height which hopefully explains why you need to explicitly set it as 50px: http://meyerweb.com/eric/thoughts/2008/05/06/line-height-abnormal/.
Here's some new CSS that fixes the font size issue in IE:
button, a {
display: inline-block;
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
margin: 10px 0;
padding: 0px;
height: 50px;
border-width: 0;
background-color: Red;
color: White;
font-family: sans-serif;
font-weight: normal;
font-size: inherit;
text-decoration: none;
line-height: 50px;
cursor: pointer;
font-size: 100%;
}
button {
#width:0px;
overflow: visible;
}
button::-moz-focus-inner {
border: 0;
padding: 0;
}
You need to use line-height property to bring your anchor tag text vertically centered
Demo
CSS
button, a {
display: inline-block;
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
margin: 10px 0;
padding: 0;
height: 50px;
border-width: 0;
background-color: Red;
color: White;
font-family: sans-serif;
font-weight: normal;
font-size: inherit;
text-decoration: none;
line-height: 50px; <-------- Here
}
add the attribute cursor:pointer; in order to add a pointer when the mouse is hover (the input not always have it)
and at last use line-height:46px; for the vertical align
