I have found a question mark in a square in css code. It belongs to a class of a font item. The CSS is generated from SCSS.
What does the question mark in the square mean? My search with Startpage didn't provide any explanation. Who can help?
The SCSS code:
This mostly is a specific icon of the font.
Because your font (currently in use - not the one used in css/scss) does not support this given character, it can not be displayed.
Update
It means your current font (to view the characters) does not support this Character.
Fonts using something like this:
Each character has his own address to identify it. And this square is outside your supported characters of your IDE/Editor.
What your using is an address (sometimes you see \E1234) to the icon search from FontAwesome.
This shows when the interpreter failed to convert. What was the SASS content for the same?

I have been using an html template that contains a slider (revolution slider - https://revolution.themepunch.com/)
It has a right and left arrow for navigating that use the following -
.tp-rightarrow.preview4:after { content: '\E824'; }
.tp-leftarrow.preview4:after { content: '\E825'; }
This works fine locally, but when I uploaded as part of an Umbraco site the two arrows changed to Chinese symbols. When I googled I found the following -
http://www.utf8icons.com/character/59429/UTF-8-character
I have now changed the CSS to display a > and < symbol but I'd like to know why the original code sometimes displays arrows and sometime displays chinese symbols.
Thanks.
U+E824 and ..25 are code points in the private use area. Code points in that area are not reserved, they do not have any pre-defined meaning. They are neither defined as Chinese characters nor arrows. You are free to use any private use code point for any purpose you wish, as long as the publisher and the client are in agreement what these code points mean.
In the browser this pretty much just boils down to having the right fonts installed/loaded/defined. In a web page, each character is simply rendered by the first defined/responsible font which happens to contain a glyph for that code point. The reason why it renders differently on two different systems/environments therefore can only stem from the fact that the CSS font definitions differ, or that the browser has different fonts installed.
Most likely the original included a custom web font which defined these characters as arrows. You have either omitted that font, or you have overridden the font precedence and made a different font apply to that element, and that font happens to define Chinese characters at those code points.
Firstly let me admit that I am a beginner in CSS. I recently came across a nice website: http://www.sitepoint.com/better-solution-managing-z-index-sass/ and was curious to know how the "3" is displayed alongside "CSS". When I tried to check through the firebug, I saw a class name ".category-css .icon-category:before" which contains content property which has some strange content.
Could you please let me know where is content property pointing to. I know this might be the silliest question, but I am clueless.
On the <i class="icon-category> they are setting a font-family: 'sitepoint', Sans-Serif;, on the :before element the content element is using a Unicode, which will relate to a character from their custom font 'sitepoint'.
For example, Font Awesome uses unicodes for it's characters, as you can see each character has a unique code next to it.
When I write CSS in Notepad++, the color coding sometimes seems inconsistent. Normally, selectors are shown in light purple but sometimes they are black for 1 or more lines consecutively. I don't see anything wrong with such lines. Why are they black? What am I missing here?
i'm not sure why that happened to you!?
but you can add keywords to notepad++ :
Setting => Style Configurator ..
Select your language and Style.
Add your keyword like color and etc , separated by space :
Usually, that sort of coloring indicates that the CSS rule immediately preceding the affected one hasn't been closed. Here's an example where I remove the closing brace from a rule in normalize.css, which affects the one that immediately follows in exactly the same way (ignoring the comment and the lack of bold type, of course):
Presumably then, the reason why the "first" declaration after that selector is affected but the subsequent ones are not is because the semicolon from the first declaration tells the syntax coloring parser to terminate the nonsensical statement which is formed by the selector. But I'm just blindly guessing.
If you're sure that the preceding rule has been closed properly, then the syntax coloring parser may have been confused. Try simply highlighting the rule, deleting it, and undoing; that usually works for me.
Since Notepad++ recognizes color of codes based on the language type, you can't able to view multiple languages with color codes in a same file. Even though CSS is a part of web designing, it is still a unique language. If you want to display the CSS codings inside the HTML to color, just change the language type to CSS (only for temporarily purpose). But, don't forget to revert the language conversion back to HTML before saving the file.
Steps: Language -> C -> CSS
I recently bought a font and wanted to embed it into my website using web fonts.
Now the problem is: After buying it, I realized that the font is missing the umlauts, such as ä, ü and ö, so it shows an empty space instead of the (missing) character.
Is there a way to prevent this? Like tell the css to use another font for the missing characters? Or would I have to edit the font itself?
Because there is no "easy", or clean way around this except remodeling the font files, here's a small JS script to replace extended ASCII chars with a <span>. (One could only do this for the exact, required characters, but you'll propably end up asking yourself the same question again once you accidentally come across another character that's not supported.)
JS only on example text:
"Hêllo wörld. ÄÖÜßäöü".replace(/([\x80-\xff])/gi, '<span class="arial">$&</span>')
Result:
H<span class="arial">ê</span>llo w<span class="arial">ö</span>rld. <span class="arial">Ä</span><span class="arial">Ö</span><span class="arial">Ü</span><span class="arial">ß</span><span class="arial">ä</span><span class="arial">ö</span><span class="arial">ü</span>
jQuery:
$('.webfont').each(function(){
this.innerHTML = this.innerHTML.replace(/([\x80-\xff])/gi, '<span class="arial">$&</span>')
});
The nodes with .webfont should only contain text, although it should also work in most other cases.
There is no acceptable way to prevent this. Use a different font. (It is possible that there is an extended version, with higher fee, of the font you bought.) The font should be selected so that it contains all characters, at least all letters, that you may need in the text.
It is possible to use different fonts for different letters in a word, using various techniques (#font-face with range settings being the most elegant, but with limited browser support). However, it means a typographic disaster. Especially if the text contains e.g. both “ü” and “u”, there is usually a striking mismatch.
Editing the font itself is technically possible using a font editor, but normally illegal unless permitted in the font license or in exemptions to copyright in applicable legislation.
So, I know that this isn't something that is normally a good idea for a website, but I have a special purpose/intent for such a use:
I have a multilingual dictionary that I'm working with online, where I need one of the languages to be in a specific font, from a file that I specify locally. However, I want this language to be rendered ONLY in this font, as if it is rendered using any other font, it will render incorrectly. That's all fine and dandy, and I can load the file in CSS and whatnot.
But I want to make it so that if it can't load that file, either for one reason or another, or something goes wrong, it can't go to another font. Basically, render this text using this font, and if you can't do that, don't just try and render it with Arial or whatever is the default -- show me blocks, show me a stark something.
I've spent a bit looking around, but am not sure what in CSS I would be using for this. Suggestions/help? Thanks :)
As an update to this question, since April 2013 there exists the Adobe Blank Font, which can be used for that purpose.
You may build a cross-browser css with FontQuirrel WebfontGenerator and the Adobe Blank font files.
If you just need the font in OpenType format you can use this single css file with the already embedded font
You can't do this. Text is text and text has to have a font that it is to be rendered in. If you really want, there's probably some weird JavaScript function that can detect the actual font being used for the text and if it doesn't match the one you want, then you can hide it or something. But in the end, your only option is to have the text displayed in some obscure font, or completely hide the text. If the text is visible, it has to be rendered using some font.
You could also theoretically create your own font where all the characters are just blank, but that seems highly illogical and such a waste of resources to make people download a font just so it can display meaningless emptiness.
There is no "don't render fonts" option. It's a font, it needs to be rendered, or else it's hidden visually in the DOM.
You could use Javascript to find out the font being applied to a certain block, and if it's not the font you want, just hide it. Or display a message.
Another solution is somehow specify the content to be empty. For example, I'm trying to override the +/- character that a Webix tree displays using Font Awesome:
#lhn-tree-container .webix_tree_open:before {
content: '';
}
This only works with the :before and :after pseudo-elements though.
