CSS: After deleting a style, it still shows up - css

After deleting some of my CSS code in a rails application, I restart the server and refresh the page and I find the code is still being used. I can still see it when I use the Chrome element inspector.
#media screen and (min-width: 961px) {
.logow { position:absolute; left:0px; top:0px;
}
body {
font-family: Verdana, Arial, Tahoma, sans-serif;
background-image: url('bg.png');
}
}
For example, if I delete the background-image: url('bg.png'); from my code, the background still stays the same. I am a CSS and rails noob so it is probably something very simple.

Press Ctl+Shift+Del and you can remove cache, cookies and whatever you want, then load your page.

This is happening because your browser is caching the page.
Make sure that you reload the page. Sometimes Opera still uses the old and cached style, which means that you should avoid Opera and use Chrome, Mozilla or Safari.
If you still have to work on Opera, delete history. Reload F5 will be sufficient on Chrome, Mozilla or Safari

CSS not working in Chrome but works in IE

It's on a simple asp.net web project. There's a Styles folder in the project and in that folder are four css files all pretty simple. Main.css has this:
body {
font-family: Arial, Helvetica, Sans-Serif;
font-size: 85%;
width: 700px;
height: 900px;
margin: 0px auto 0px auto;
padding: 10px;
border: 2px;
background-color: green;
}
The green (it was originally white) shows up in IE but not in Chrome. I reference the css files in the ASPX file:
<link href="Styles/CheckOut.css" rel="Stylesheet" type="text/css"/>
<link href="Styles/Main.css" rel="Stylesheet" type="text/css" />
The green was only one test. I made other changes to the css files and none showed up in Chrome. Aside from the css issue, the app performs fine in Chrome as well as IE.
The Page Inspector reflects the css files; but Chrome does not. There are a couple of similar seeming questions here but none address my issue, AFAIK.
When you refresh the page in Chrome, do you have dev tools open? And if you do, do you have "Disable cache (while DevTools is open)" checked? I've found that Chrome is pretty aggressive about caching stuff, so if you're not seeing your changes this might be something to look into. (You can verify if that checkbox is marked by hitting F12 on Windows or option-command-I on Mac, and clicking on the widget wheel. It's the first checkbox under "General".)

Rotated text using Courier font not displayed in Opera

I have the following HTML:
<div class='box'>text</div>​
and CSS:
.box {
/* non-essential */
display: inline-block;
margin: 2em;
background: plum;
/* ESSENTIAL */
transform: rotate(45deg);
font-family: Courier;
}​
And this is the fiddle. I've omitted the prefixes here, but they are in the fiddle.
Expected result:
It is also the result I get in Chrome, Firefox, IE9, Safari.
However, in Opera it looks like this:
If I take out the transform (that is, the div is not rotated
anymore), then the text is shown.
If I replace the font with another one, then the text is shown.
So why is this happening and what other solutions do I have?
In case this helps:
Why is this happening
It's happening because Opera has resolved Courier to courier.fon a bit-mapped font, and Opera has not implemented rotation for bit-mapped fonts.
You get the same results with Modern and Roman and any other font where you have a .fon version.
You can look in C:\Windows\Fonts for a complete list.
What other solutions do I have
If you are relying on the exact metrics of the font when it is presented on the page, you may want to consider using a web font.
If calling the font "courier" is important, then you could ignore opera: It's not very popular, this is a bit of an obscure bug, and since Opera is ditching Presto for Webkit, it simply involves waiting.
If you change the font-family tag to the below it works:
font-family:"Courier New", Courier, monospace;

Apply style ONLY on IE

Here is my block of CSS:
.actual-form table {
padding: 5px 0 15px 15px;
margin: 0 0 30px 0;
display: block;
width: 100%;
background: #f9f9f9;
border-top: 1px solid #d0d0d0;
border-bottom: 1px solid #d0d0d0;
}
I only want IE 7, 8, and 9 to "see" width: 100%
What is the simplest way to accomplish this?
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
#myElement {
/* Enter your style code */
}
}
Explanation: It is a Microsoft-specific media query. Using -ms-high-contrast property specific to Microsoft IE, it will only be parsed in Internet Explorer 10 or greater. I have used both the valid values of the media query, so it will be parsed by IE only, whether the user has high contrast enabled or not.
Update 2017
Depending on the environment, conditional comments have been officially deprecated and removed in IE10+.
Original
The simplest way is probably to use an Internet Explorer conditional comment in your HTML:
<!--[if IE]>
<style>
.actual-form table {
width: 100%;
}
</style>
<![endif]-->
There are numerous hacks (e.g. the underscore hack) you can use that will allow you to target only IE within your stylesheet, but it gets very messy if you want to target all versions of IE on all platforms.
Apart from the IE conditional comments, this is an updated list on how to target IE6 to IE10.
See specific CSS & JS hacks beyond IE.
/***** Attribute Hacks ******/
/* IE6 */
#once { _color: blue }
/* IE6, IE7 */
#doce { *color: blue; /* or #color: blue */ }
/* Everything but IE6 */
#diecisiete { color/**/: blue }
/* IE6, IE7, IE8, but also IE9 in some cases :( */
#diecinueve { color: blue\9; }
/* IE7, IE8 */
#veinte { color/*\**/: blue\9; }
/* IE6, IE7 -- acts as an !important */
#veintesiete { color: blue !ie; } /* string after ! can be anything */
/* IE8, IE9 */
#anotherone {color: blue\0/;} /* must go at the END of all rules */
/* IE9, IE10, IE11 */
#media screen and (min-width:0\0) {
#veintidos { color: red}
}
/***** Selector Hacks ******/
/* IE6 and below */
* html #uno { color: red }
/* IE7 */
*:first-child+html #dos { color: red }
/* IE8 (Everything but IE 6,7) */
html>/**/body #cuatro { color: red }
/* Everything but IE6-8 */
:root *> #quince { color: red }
/* IE7 */
*+html #dieciocho { color: red }
/* IE 10+ */
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
#veintiun { color: red; }
}
There are severals hacks available for IE
Using conditional comments with stylesheet
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="only-ie.css" />
<![endif]-->
Using conditional comments with head section css
<!--[if IE]>
<style type="text/css">
/************ css for all IE browsers ****************/
</style>
<![endif]-->
Using conditional comments with HTML elements
<!--[if IE]> <div class="ie-only"> /*content*/ </div> <![endif]-->
Using media query
IE10+
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
selector { property:value; }
}
IE6,7,9,10
#media screen and (min-width: 640px), screen\9 {
selector { property:value; }
}
IE6,7
#media screen\9 {
selector { property:value; }
}
IE8
#media \0screen {
selector { property:value; }
}
IE6,7,8
#media \0screen\,screen\9 {
selector { property:value; }
}
IE9,10
#media screen and (min-width:0\0){
selector { property:value; }
}
As well as a conditional comment could also use CSS Browser Selector http://rafael.adm.br/css_browser_selector/ as this will allow you to target specific browsers. You can then set your CSS as
.ie .actual-form table {
width: 100%
}
This will also allow you to target specific browsers within your main stylesheet without the need for conditional comments.
I think for best practice you should write IE conditional statement inside the <head> tag
that inside has a link to your special ie style sheet.
This HAS TO BE after your custom css link so it overrides the latter,
I have a small site so i use the same ie css for all pages.
<link rel="stylesheet" type="text/css" href="index.css" />
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->
this differs from james answer as i think(personal opinion because i work with a designer team and i dont want them to touch my html files and mess up something there) you should never include styles
in your html file.
A bit late on this one but this worked perfectly for me when trying to hide the background for IE6 & 7
.myclass{
background-image: url("images/myimg.png");
background-position: right top;
background-repeat: no-repeat;
background-size: 22px auto;
padding-left: 48px;
height: 42px;
_background-image: none;
*background-image: none;
}
I got this hack via: http://briancray.com/posts/target-ie6-and-ie7-with-only-1-extra-character-in-your-css/
#myelement
{
color: #999; /* shows in all browsers */
*color: #999; /* notice the * before the property - shows in IE7 and below */
_color: #999; /* notice the _ before the property - shows in IE6 and below */
}
Welcome BrowserDetect - an awesome function.
<script>
var BrowserDetect;
BrowserDetect = {...};// get BrowserDetect Object from the link referenced in this answer
BrowserDetect.init();
// On page load, detect browser (with jQuery or vanilla)
if (BrowserDetect.browser === 'Explorer') {
// Add 'ie' class on every element on the page.
$('*').addClass('ie');
}
</script>
<!-- ENSURE IE STYLES ARE AVAILABLE -->
<style>
div.ie {
// do something special for div on IE browser.
}
h1.ie {
// do something special for h1 on IE browser.
}
</style>
The Object BrowserDetect also provides version info so we can add specific classes - for ex. $('*').addClass('ie9'); if (BrowserDetect.version == 9).
Good Luck....
For IE9+
#media screen and (min-width:0\0) and (min-resolution: +72dpi) {
// IE9+ CSS
.selector{
color: red;
}
}
IE Edge 12+
#supports (-ms-ime-align: auto) {
.selector {
color: red;
}
}
This one works on Edge and all IEs
:-ms-lang(x), .selector { color: red; }
It really depends on the IE versions ... I found this excellent resource that is up to date from IE6-10:
CSS hack for Internet Explorer 6
It is called the Star HTML Hack and looks as follows:
html .color {color: #F00;}
This hack uses fully valid CSS.
CSS hack for Internet Explorer 7
It is called the Star Plus Hack.
*:first-child+html .color {color: #F00;}
Or a shorter version:
*+html .color {color: #F00;}
Like the star HTML hack, this uses valid CSS.
CSS hack for Internet Explorer 8
#media \0screen {
.color {color: #F00;}
}
This hacks does not use valid CSS.
CSS hack for Internet Explorer 9
:root .color {color: #F00\9;}
This hacks also does not use valid CSS.
Added 2013.02.04: Unfortunately IE10 understands this hack.
CSS hack for Internet Explorer 10
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
.color {color: #F00;}
}
This hacks also does not use valid CSS.
For /* Internet Explorer 9+ (one-liner) */
_::selection, .selector { property:value\0; }
Only this solution perfectly work for me.

How to Hide CSS from Older Browsers Like Internet Explorer
Here is a COMPLETE Javascript-free, CSS-based solution that allows you to target Internet Explorer 1-11! My solution below works by hiding IE1-7 from all your modern sheets using #import, giving IE1-7 a clean, white page layout, then uses three simple CSS media query "hacks" to isolate IE8-11 in the imported sheet. It even affects IE on Mac. And no IE conditional comments are needed.
With this solution you will never have to customize your web applications for Internet Explorer ever again, and can safely move forward using cutting edge CSS in all your websites. Best of all it requires NO JavaScript to work!!
HOW IT WORKS
First create three CSS style sheets:
"OldBrowsers.css"
"ModernBrowsers.css"
"Import.css".
The first style sheet, "OldBrowsers", is a basic element "reset" style sheet that gives all browsers, old and new, a simple white, block-level layout and where you can style all the elements for every web browser ever made. This allows 20+ years of web browsers and their elements to all use the same HTML designs and look alike. This sheet is also seen by IE1-11. Add in this sheet all basic styles needed to style the elements only. The second sheet, "ModernBrowsers.css", is where you can safely put all your modern, cutting-edge CSS that styles both the elements with HTML5 modern designs, but control layouts, etc. IE1-7 will NOT see this sheet. The third sheet is an import sheet, "Import.css", that will load the second sheet mentioned above and all your advanced CSS style sheets using a single #import rule. This hides your modern style sheet from wide range of older browsers, including IE1-7. IE1-11 will see the "Import.css" sheet, but IE1-7 will not see "ModernBrowsers.css" sheet because of the #import rule.
<link media="screen" rel="stylesheet" type="text/css" href="OldBrowsers.css" />
<link media="screen" rel="stylesheet" type="text/css" href="Import.css" />
In your "Import.css" sheet add this #import rule exactly as formatted below. This "ModernBrowsers.css" sheet will be hidden from IE1-7 and a wide range of older browsers listed below:
#import 'ModernBrowsers.css' all;
All CSS in this imported sheet will be hidden from Internet Explorer 1-7 and a wide range of older browsers. IE1-7, and a wide range or older browsers, do not understand media type "all", nor the specific #import format shown above, so will fail to import this sheet. This specific version of import is not recognized by many older browsers (pre-2001). Those browsers are so old now, you just need to deliver them a clean white web page with stacked blocks of content.
The CSS you add to "OldBrowsers" allows you to set up old browsers and IE1-7 to use plain styling you control. I personally add only HTML "reset" element styling in this sheet and make sure all the HTML5 elements have simple clean designs. Newer browsers will cascade over these in the "ModernBrowsers.css" style sheet.
In "ModernBrowsers.css" you want to add all your modern styles, but also have special CSS hacks to target Internet Explorer 8-11 using CSS media queries (alongside all your normal selectors and classes). Simply add the following IE-only fixes to your modern style sheet to target these last specific IE browsers. Drop into these blocks any styles specific to these old IE browsers.
Note: Keep in mind HTML5 and most of CSS3 is generally supported starting with Internet Explorer 9 through 11. But there are bugs, missing element support, and other issues with IE8-11 and even the Trident Edge browsers miss. But you now can safely target these older IE 8-11 browsers this way, while using your cutting-edge CSS inside this sheet for all other modern browsers going forward:
/* IE8 */
#media \0screen {
body {
background: red !important;
}
}
/* IE9 */
#media all and (min-width:0\0) and (min-resolution:.001dpcm) {
body {
background: blue !important;
}
}
/* IE10-11 */
#media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
body {
background: green !important;
}
}
Simple! You have now targeted styles for IE1-11 (all Internet Explorer browsers!)
With this solution you achieve the following:
The #import excludes IE 1-7 from your modern styles, completely! Those agents, along with the list below, will never see your modern imported styles and get a clean white style sheet content page older browsers can still use as far as viewing your content (use "OldBrowsers.css" to style them). The following browsers are excluded from "ModernBrowsers.css" using the above #import rule:
Windows Internet Explorer 1-7.x
Macintosh Internet Explorer 1-5.x
Netscape 1-4.8
Opera 1-3.5
Konqueror 1-2.1
Windows Amaya 1-5.1
iCab 1-2
OmniWeb
In your "ModernBrowsers" imported sheet, you can now safely target IE browsers version 8-11 using simple media query "hacks".
This system uses a simple #import style sheet system that is fast and manageable using traditional, non-support for external style rules rather than CSS fixes sprinkled throughout multiple sheets. (BTW...Do not listen to anyone saying #import is slow, as it is not. My import sheet has ONE LINE and is maybe a kilobyte or less in size! #import has been used since the birth of the WWW and is no different than a simple CSS link. Compare this to the Megabytes of Javascript kids today are shoving into browsers using these new "modern" ECMAScript SPA API's just to display a tiny paragraph of news!) One #import line now separates years and years of IE browser version from your newer CSS code and fancy layout designs. No scripting needed!
All old IE browsers and a wide range of other user agents are excluded from modern styles now using this import strategy, which allows these older browsers to collapse back to plain, "block-level", white pages and stacked content layouts that are fully accessible by older browsers. You can now spend MINIMAL time customizing your content for old browsers and instead let them see plain white stacked content pages for thousands of pages in your website!
Notice this solution has no IE conditional comments! You should NEVER use those since IE 10-11 no longer support IE conditionals.
With this solution, your modern web designs are now 100% free to use custom, cutting-edge CSS3 technologies without having to ever worry about older browsers and IE1-11 ever again!
Linked CSS has very wide support, even in older CSS1 browsers going back to 1995. It is just one more reason to NOT USE EMBEDDED or "style" element styles. Use these linked CSS designs, instead.
If you added a really good set of "reset" or element styles into the "OldBrowsers" style sheet, 20+ years of old and new browsers and their basic element designs will allow your core web page design to look the same using that one sheet. The idea with "reset" element CSS is to force all browsers through history, and their shared HTML element support, to look the same BEFORE you apply CSS layouts, scripting, and fancier CSS designs. The HTML basic elements have change very little in the past 25 years. So styling elements first to simplify text content display makes sense.
This is part of the new "progressive" CSS, 100% JavaScript-free, design concept in 2021 for addressing cross-browser style issues, where older agents are allowed to degrade gracefully to simpler layouts rather than struggling to fix problems in cryptic old, broken, box-model agents (IE5-6) in a piecemeal fashion to match complex CSS layouts. Most older web browsers do NOT need to recreate your custom layouts any longer. They just need to display basic text and media content. With the long tail of their slow demise online, IE 1-11 just need simple layout designs so the content is readable and accessible.
The advantage to this strategy is its 100% Javascript-free! You should NOT be using scripting to manage CSS in web browsers in 2021, anyway. I recommend you dump Modernizr and all "polyfills" and try my clean CSS solution instead when managing Internet Explorer in web browsers. My solution is effective in targeting IE1-11, giving you complete control over how you customize CSS for those targeted browsers, while freeing you up as a designer to focus on newer CSS3 and cutting-edge styles and layouts in Edge and all other modern HTML5 browsers going forward. I have been using a version of this since 2004, but recently updated it for 2021.
It's my hope we stop creating these gigantic, multi-megabyte, CPU-hog, JavaScripted, polyfill nightmare scripted solutions for addressing what used to be solved years ago with a few lines of simple Cascading Style Sheet code. :)
You can get my complete Universal CSS Framework from Git for free, which uses this same code plus even more goodies!

Fonts in IE look awful

Fonts in the latest Chrome, Opera, Safari and Firefox look fine but in IE9 they look blurry and small in comparison. On other sites they look alright though?
Is there anything I can change in CSS to make them all look the same? Mainly the size as it makes the whole website look odd...
I'm using the following CSS:
margin: 0px;
padding: 0px;
font: 11px Verdana, Arial;
line-height: 13px;
Declaring
<!DOCTYPE html>
will make IE9 behave just that bit better.
I would look in HTML5 Boiler Template. They've already solved all these little quirks and created a nice boilerplate for people to use.

CSS that firefox and not webkit can read

Is there a way to specify some CSS that firefox can read but webkit browsers cannot, or visa versa?
Seems you are not alone who wants this:
Targeting only Firefox with CSS
And you can view more tricks here:
http://stephenkui.com/code-css-only-to-firefox-ie-or-safari/
You could use javascript to do that..
there is also a hack
#-moz-document url-prefix() {
#my-id { font-size: 100%; }
}
This should target only firefox and not other browsers
