I have an HTML element textarea with defined CSS rule { resize: both }. In FF when the user mouse over the right bottom corner of textarea the cursor changed according to value of property resize, but in Chrome cursor doesn't change.
Please open this example in FF and Chrome to check the difference.
Is it a bug of Google Chrome and can I fix it with CSS on my side?
Update
I reported bug to Chromium:
https://bugs.chromium.org/p/chromium/issues/detail?id=942017
Update 2
The bug was fixed in Chrome 80.
Actually, there are, or at least were ways in which you could style the resizer and add cursor: se-resize; on hover. Check out this post: Can I style the resize grabber of textarea?
It describes how you can use ::-webkit-resizer to style the resizer:
::-webkit-resizer {
border: 2px solid black;
background: red;
box-shadow: 0 0 5px 5px blue;
outline: 2px solid yellow;
}
Unfortunately it stopped working in Chrome and I couldn't anything similar. (I think it still works in Safari).
But fear not, it's not hard to make a custom handle. Actually, I would encourage you to use a custom one as the default one is too small and hard to hit. Especially with touch. There are actually a lot of sites that use custom handles (or at least automatic resizers based which grows based on the content. Works great on touch too!).
Ie. Stackoverflow uses a custom handle (TextAreaResizer):

There are also lots of libraries for exactly that purpose, just do a Google search, and you'll find something that works for you :)
This is rendered by browser itself cant be designed using css
I'm styling some select inputs on a page, and it works fine on Windows Chrome. However, on Mac Chrome, the "native" implementation refuses to go away unless I apply -webkit-appearance: none; The problem with this, of course, is that I lose the down arrow that indicates it's a select element, which I would otherwise be able to add back in if inputs were allowed pseudo-elements (they're not).
Specifically, I'm trying to override the border-radius property, but no amount of border-radius: 0!important will override it.
Create or download a small down arrow and then give the following property to you select:
select{-webkit-appearance: none;
background:url(images/downarrow.png) no-repeat;
background-position: 98% 4px; }
I am developing a mobile website and testing on both iPhone and android phone.
I changed the appearance of select boxes on the page using CSS.
This displays good in the iPhone browser, but in Android does not apply the styles correctly.
The original dropdown arrow remains present (and is stretched vertically due to the height property).
Is there any way of telling the browser how to style this element on a android device? Or is it not supported?
Here is a sample of my code:
HTML:
<div class="filter-group">
<select class="bigInput" id="f_eventWho" name="f_eventWho" tabindex="1">
<option id="f_public" selected="selected">For Everyone</option>
<option id="f_private">By invitation</option>
<option id="f_both">All Gatherings</option>
</select>
</div>
CSS:
.bigInput
{width: 125px;
height: 50px;
background-size: 15px;
background: rgb(159, 209, 225) url(../img/small_down_arrow_20.png) no-repeat right;
border: none;
margin: 5px;
font-size: 14px;
}
There is no consistent way to style native selectboxes in browsers, let alone in mobile.
The best workaround I've found is to create an HTML dropdown that emulates the selectbox behavior - I highly recommend SelectBoxIt if you're using JQuery: http://gregfranko.com/jquery.selectBoxIt.js/
All you have to do is call $('select').selectboxit(); and it replaces all select boxes on the page with stylable html elements that behave the exact same way. Best of luck!
The best solution is to not try and style select elements, especially not on mobile devices.
Doing so is both damaging to usability and performance, it's raising your middle finger to visitors and letting them know you really don't care about them at all.
Please try and justify the enormous overhead (please look at what a lib like selectBoxIt will do to page-weight) you will be adding against the benefit you will provide to visitors (which is zero, at best).
I need to change background color of the navigation menu specified by this CSS file (it's used in this Jquery example). I cannot figure out where is this line. Please help.
If I understood correctly, the class you need to change is called '.ui-widget-header', and it looks like this:
.ui-widget-header
{
border: 1px solid #aaaaaa;
background: #cccccc url(images/ui-bg_highlight-soft_75_cccccc_1x100.png) 50% 50% repeat-x;
color: #222222;
font-weight: bold;
}
Simply open your CSS file in any editor, use the Find function (usually CTRL + F) and look for '.ui-widget-header'. Then you can change the background color and image if you have basic CSS knowledge. If not, please ask for assistance.
As #drinchev said, in the future if you need to find a specific element just mouse over it and use 'Inspect Element', assuming you are using newer versions of Mozilla Firefox or Google Chrome. In case you are using Internet Exporer, press F12 and use the 'Select Element' pointer over the needed item.
You can also dynamically change values with those Developer Tools to see how would it look like if you made the changes for real.
P.S.: Keep in mind that I reformatted the CSS a bit, because it was put in a single line.
Use inspect element on chrome or the Firebug for Firefox.
Click on the element to obtain all the css styles and their parent styles. Change the value directly by double clicking & check for the result once.
How can I hide the div without using display:none or JavaScript?
In my country, a lot of Blackberrys come with the CSS support disabled (the mobile companies here are not so good to developers). I have text that says
<div class="BBwarn">
please activate your css support and a link
</div>
I want to hide that once the user activates CSS support, but i can't use display:none; because it is only supported in BB firmware 4.6. It is a public site and I can't make all my visitors upgrade.
Does anybody knows a solution to this? I hope the question is easier to understand now.
Update:
Thank you all for the answers but I can't use
position:absolute
overflow
because they are available from Blackberry firmware 4.6 and up
things to try:
use the z-index to put it behind some other element
move it off the screen by absolute positioning
visbility: hidden
make the content "invisible" by setting background to foreground color (works only for text)
opacity: 0
but the real question is: why?
This is a common way:
margin-left: -9999;
How about:
visibility: hidden;
That should hide the DIV, (note how it will still be rendered but be invisible, that means it will take space in the document as if it was visible, but be invisible (unlike display:none; where the div will not be rendered)).
<div style="height:0;width:0;overflow:hidden;">
<!-- content here -->
</div>
Incidentally, this is what I do to preload images, which is nice because it doesn't use javascript.
Visibility:hidden won't do the same thing because some browsers are smart and won't make the request unless it thinks its actually visible.
Why not try the simple:
position: absolute;
left: -1000px;
I can't see why it wouldn't work.
I'm not sure of the percentages you're talking about that are using < 4.6, but if it's that important to you, then I can see a rationale for accepting that you can't please all the people all the time, and an acceptable cascading solution to this should be achievable. Probably with a link to explain the benefits of upgrading and enabling css.
height: 0;
overflow: hidden;
visibility: hidden;
color: #fff;
background: #fff;
BTW - you'd better make sure that you're css is good if you're telling someone to turn it on... :-)
What makes you think display: none is not supported before version 4.6? Did you test that, or are you going by their documentation?
I'm not a mobile developer either, so I'm just going by what I gleaned from the documentation.
The BlackBerry Browser 4.6 CSS Reference indeed mentions "Availability: BlackBerry® Device Software version 4.6 or later" for the display property, but their BlackBerry Browser 4.3 Content Developer Guide indicates that 4.3 already supported a very limited version of the display property, including display: none. Versions before 4.3 don't support the display property (again, going by the BlackBerry Browser developer documentation).
Can you assume your users do at least have firmware version 4.3, or is that just as unacceptable as assuming they have 4.6?
Have you tried simply setting the width and height to zero? I'm not familiar with the BlackBerry (Browser), but I'm sceptically assuming its CSS support is less than perfect, certainly on the older versions. I wouldn't be surprised if this worked:
.BBwarn {
display: none; /* for 4.6 and up */
width: 0px; /* for 4.3 */
height: 0px;
}
But then width and height are only supported on all elements starting from version 4.3. Before that they could only be applied to <button> and <img> tags and some <input> types (according to the documentation).
So perhaps the safest way to really make it work on all BlackBerry firmware versions is to use an image for the warning, and use CSS to set its width and height to zero.
If an image is not an option (due to lozalization issues or so, perhaps), an ugly hack might be to specify an empty/illegal image source and put the warning text in the alt attribute. I don't know if setting its width and height to zero would still hide that alt text then.
visibility: hidden; will work, but the space taken up by that particular div will still appear. If you are going to use the negative left-margin method, remember that you will need to set the object's position to absolute.
How about this:
clip: rect(0,0,0,0);
Note: Please note the clip property does not work if "overflow:visible" is used.
In your case:
<div class="BBwarn">
please activate your css support and a link
</div>
just add this css:
.BBwarn{
position: absolute;
clip: rect(0,0,0,0);
}
You could position it absolutely off the screen.
But I, also, am not a mobile developer.
I assume You don't want to use JavaScript because the Blackberrys don't support it.
What about if you did the opposite and displayed the block of code with JavaScript, rather than tried to hide it?
<script type="text/javascript"><!--
document.open();
document.writeln('<div class="BBwarn">');
document.writeln('please activate your css support and a link');
document.writeln('</div>');
document.close();
//--></script>
This is a bit of a hack, but would not display the text with disabled JavaScript...
You can do something like wise:
.class{
opacity:0; overflow:hidden; visibility: hidden; height:0;
}
for being more precise you can add :
color:transparent; background-color:transparent;
What exactly is wrong with (the earlier mentioned)
width: 0
height:0
visibility: hidden
width: 0 height:0 visibility: hidden
...Does not always work with firmware 2.2 and older. Sometimes you can get an element to be hidden, but it will reappear with certain keystrokes (like underscore, for instance).
Or you could use Please enable Javascript
And use an image that reads "Enable CSS" and style it using "display:none".
So that whenever the corresponding feature is enabled these warnings wont show.
Alternately, I presume you are using some server side code? You could try detecting for the most common known platforms that support specific versions of css/javascript and deliver content accordingly. You might not even have to write it all yourself.
I had a similar problem when I was trying to customize a select box using javascript in BlackBerry Curve 8530 (OS 5.0). But, the menu created couldn't be hidden because the css following properties still don't work:
display
overflow
position: absolute
visibility
z-index
And destroying and recreating the HTML elements didn't work either, so I got here and could solve my problem.
I know my answer isn't exactly about the question raised here, but once I got here when had problems, I think I'm not the only one with it happened and is going to.
Anyway, even if those css properties worked, what I needed was some code that could work on the most of the BB models.
My solution was made using all the answers found here. It was simple. I made two classes:
.element
{
width: 100px;
height: 100px;
font-size: 12px;
color: black;
background-color: transparent;
border: 1px solid black;
}
.element_hidden
{
width: 0px;
height: 0px;
font-size: 0px;
color: white;
background-color: white;
border: none;
}
Yes. I've made two of them for each kind of element I had in my page.
Initially, all classes are set to class="element_hidden", so when the mouse is over the select box menu, all the classes are changed to class="element" and they are shown and hidden as if they were made invisible/visible.
I hope this can be useful to someone! ;D
We can use the transform property to scale the element along the x and y axis.
. BBwarn{
transform : scale(0,0);
}
I used font size to obtain this without using display none
font-size: 0px;
As you said in question that you need solution for Blackberry version below 4.6 and there are very few CSS properties supported for Blackberry version below 4.6 so we can use some sort of hack for this purpose. Try and set the text color to whatever the background is or set font-size to 0. It's a hack, but it makes it invisible. Run the following snippet and let me know if its works for you.
.alert1 {
color: #fff; //3.8 or later
}
.alert2 {
font-size: 0; //3.8 or later
}
<b>Alert1</b>
<div class="alert1">
please activate your css support and a link
</div>
<b>Alert2</b>
<div class="alert2">
please activate your css support and a link
</div>
