I've set the font-family of a div to "Vermin Vibes", fantasy, serif;, so that if the first font is not avaiable, the browser will automatically use the next one
#myheader {
position: sticky;
top: 1rem;
text-align: center;
font-family: "Vermin Vibes", fantasy, serif;
font-size: 6rem;
}
The problem is that when the font changes family, it changes his size and his alignment from the top of the screen...
How can I set top and font-size to change when font-family changes?
CSS is only concerned with how your content is styled. You might have fonts dependent on the content, so a solution would be modifying your HTML since HTML is for defining the actual content of the page. I think this would be more related to investigated browser compatibility for your client.
By the time a fallback font-family is determined, the content has already loaded. So you'll need Javascript for that.
So determine where the processing for CSS styles will happen before it is compiled and evaluated by your browser. You may have to extract the font-family using Javascript and set styles conditionally if you are using plain CSS without a preprocessor.

I want my website to adapt dynamic font-size for iOS. So If you change font-size in settings (Settings > General > Accessibility > Larger Text on your iPhone), your webpage font-size should adjust based on that.
I have font: -apple-system-body added in html root. And throughout the website I am using rem to adjust font-size relative to html root.
So it's working but the problem is -apple-system-body gives font-size: 16px by default which is too high for my page. I want to convert that to 10px; So my html root font-size should be 62.5% of what the system gives always.
Currently I am achieving that using javascript with something like this :
document.documentElement.style.fontSize = document.documentElement.style.fontSize * 0.625;
Was wondering if there's css only way to solve this.
You could use the css calc() function. Inside this function, you can perform operations. For example:
font-size: calc(1rem * 0.625);
For more info: https://css-tricks.com/a-complete-guide-to-calc-in-css/
Yes, set the HTML size to 62.5%. This will honour system settings (the 10px is a fallback for ancient browsers, not really needed)
html{
font-size: 10px;
font-size: 62.5%;
}
Ensure you definitely have rem or em units everywhere if you do this though.
I am using a downloaded font file for use on my website, however it is causing some issues in regards to layout / display.
Most fonts I have used display like this
The font I am currently using displays like this:
The difference is that the 1st font has space above (which is part of the actual text and not my css styling) while the second one has no space at all.
I can solve this issue by simply adding some extra padding to the containing element's top but this is not practical in the future event that I decide to replace the font (meaning I would have to go into every parent and remove the padding-top)
Is there any CSS styling methods I can use to add padding to my font so that it will always have a bit of space up top?
My Code:
CSS:
#font-face {
font-family: "Anakin Mono";
src: url("../fonts/opipik_anakinmono/anakinmono.ttf");
}
#demo {
font-family: "Anakin Mono";
padding: 14px 10px 10px 10px; /* Have to add extra padding to top becuase of font in use */
border: 1px solid black; /* A border helps illuminate whats happening with text alignment - vertically;
}
HTML:
<p id="demo">Some text on my website</p>
Is there any CSS styling methods I can use to add padding to my font so that it will always have a bit of space up top?
Unfortunately the answer to this question as you've outlined it is no, there are no CSS methods to target only a single font.
That said, you can simply assign your mono-spaced font by using a class and easily change the style globally as shown here:
#import url('https://fonts.googleapis.com/css?family=Inconsolata');
.monospace {
font-family: 'Inconsolata', monospace;
padding-top: 4px;
}
<div class="monospace">This element is monospaced font</div>
Any elements which you'd like to use your mono spaced font should be assigned the class monospace. In the future, you can simply change the font-family rule and alter the padding and voila, you've accomplished your change with very little effort.
I realize you've made it clear in the comments that you'd rather take a different approach, but I feel this is the absolute best solution/workaround that will get you what you want with the least amount of effort. At most, it will require you alter your markup to add the monospace class where needed, but this is probably a step in the right direction anyway.
You can make use of line-height. Change your CSS to this:
#demo {
font-family: "Anakin Mono", sans-serif;
line-height: 3;
padding: 0 10px;
border: 1px solid black;
}
You can try different values of line-height. It accepts multiple of original line height. px or em.
Always remember not to use only ONE font in font-family. Use more than 1 font to provide fallback fonts, in case your font is not loaded yet / unable to load.
Also, it's not advised to use self-hosted TTF font unless the file size is small. Try using CDN-hosted web fonts (such as Google Fonts) for better performance.
JSFiddle demo: https://jsfiddle.net/okawrcuf/6/ (I used another font that is available in Google Fonts for demo purpose, as I don't have your font)
I've found an inconsistency among browsers in handling font-size (on Mac OS X 10.11.4). I'd like to know if this is a bug in Firefox, or a bug in CSS, or am I not understanding something about CSS?
This JSFiddle shows the details. In a section like this:
<pre>Start of pre section
<code>**problem here!**</code>
End of pre section
</pre>
the style code { font-family: Courier; } changes the font-size shown by Safari and Chrome, but not in Firefox. Yet in other sections, the code element size increases from 13px to 16px in all the browsers.
Why does the font-size increase from 13px to 16px after setting the font-family in all browsers?
Perhaps Firefox is changing the font-family but not the font-size. Yet it does change the font-size in other places, like in code inside a p element or inside a list.
I'm guessing the solution is to just aggressively set explicit font size with pixel units wherever I care about it (ignoring accessibility).
Quote from possibly related Firefox bug from 2006: Bug 328621 - strange default monospace font size -- differs from the proportional fonts
Though the inter-browser portability problem this imposes doesn't seem that trivial to me. The last time I wanted to markup HTML so that the monospaced parts showed the same in both Mozilla and M$IE I had to resort to absolute font sizes, which should be certainly avoided due to the accessibility problems they impose.
And yes, there's a simple workaround -- changing the settings. But most of the users will use defaults. :-(
This issue is not new; it has been known for many years that browser handling of monospace fonts is incredibly screwy and inconsistent across browsers. A number of workarounds are available that don't require you to override the monospace font preference set by the user, the most perplexing of which is to specify
font-family: monospace, monospace;
That's right: two monospace keywords at the end of the font stack. Nobody knows why this works; it just does.
For what it is worth, Firefox's UA stylesheet contains references to a -moz-fixed keyword which refers to the preference that is set by the user, which includes both the family and the size despite it being a value for the font-family property. Firefox ships with the preference set to 13px in whichever the system's default monospace font is. It would seem that monospace, monospace forces the browser to compute the element's font-size according to the spec while still preserving the preferred monospace family, at least. But this is just a guess.
Is this a bug? It depends on whom you ask. If you ask browser vendors, they'll probably say this is intentional. If you ask other authors, they'll probably also call it a bug. Is this a spec violation? No, because the spec allows browsers to implement defaults however they like.
Why does the font-size increase from 13px to 16px after setting the
font-family in all browsers?
probably because the browser's default stylesheet has these settings.
I'm guessing the solution is to not try to understand all this but
just aggressively set font and font-size wherever I care about it.
Not sure what you mean by "agressivly" but yes: If you have particular demand for that style, set it as precisely as possible in your own stylesheet, including font familiy, weight, size etc.
Since I asked the question and got a couple of good faith answers that are however not really answering my question: I'm going to try to prove that this really is a problem with current browsers. See my comment at the end about why this might or might not matter.
Here then are
3 problems with font-size in CSS/HTML in FireFox, Chrome and Safari on Mac OS X 10.11.4:
Problem 1. Changing font-family should not change font-size, but it sometimes does.
I don't know what the "user agent stylesheet" is. There can be all kinds of settings on it. But regardless of those settings, changing font-family should not change computed font-size. (Some fonts might appear larger at the same font size compared to other fonts at same font size, so visually they can look bigger or smaller, but the computed font size number should not change).
notation: in the following
pre(code) means roughly <pre><code>text here</code></pre>
p(code) means roughly <p><code>text here</code></p>
In the default situation, a page with no styles, I see this in all 3 browsers:
pre=13px
pre(code)=13px
p=16px
p(code)=13px
<pre>pre <code>pre(code)</code></pre>
<p>paragraph <code>p(code)</code></p>
Perhaps the user agent stylesheet is something like this:
pre { font-size: 13px }
code { font-size: 13px }
p { font-size: 16px }
The user agent can't be using relative sizes for code, because it appears as 13px inside of both pre and p elements. So it could be this:
pre { font-size: 81.25% }
code { font-size: 13px }
p { font-size: 100% }
or the equivalent using em instead of percentage. Or perhaps a descendent rule with percentages or em:
pre { font-size: 81.25% }
pre code { font-size: 100% }
p { font-size: 100% }
p code { font-size: 81.25% }
But then how do we explain this:
After setting code { font-family: Courier } (or any font family other than monospace) we get:
pre=13px
pre(code)=16px for Chrome & Safari pre(code)=13px for FireFox
p=16px
p(code)=16px
code { font-family: "Courier"; }
<pre>pre <code>pre(code)</code></pre>
<p>paragraph <code>p(code)</code></p>
No matter what the stylesheet is, the font-size should not change after only changing the font-family.
Problem 2. Relative font-size should be based on parent element's computed font-size. But it sometimes is not.
With no styles we have:
p=16px
p(code)=13px
After setting code { font-size: 100%; } we should have
p=16px
p(code)=16px
Instead we still have:
p=16px
p(code)=13px
This is wrong because author style should override default user-agent (browser) style. And relative (percentage) font-size is based on the parent element's computed font-size.
code { font-size: 100%; }
<p>paragraph <code>p(code)</code></p>
Similarly, after setting code { font-size: 120%; } we should have
p=16px
p(code)=19.2px = 16px * 1.2
Instead we have:
p=16px
p(code)=15.6px = 13px * 1.2
code { font-size: 120%; }
<p>paragraph <code>p(code)</code></p>
This shows that parent element is being ignored, and that some phantom value of 13px is being used to calculate the relative font-size.
Problem 3. The standard advice to use html { font-size: 62.5% } and then use em or rem for font-sizing does not work correctly
(Note: FireFox with rem does seem to be correct)
(Note: using the also recommended body { font-size: 62.5% } seemed to produce some crazy results, like doubling of font sizes, so I'm not considering that here.)
With html { font-size: 62.5%; } and code { font-size: 1.6em; } we have:
p=10px
FireFox: p(code)=13.0167px
Chrome: p(code)=13px
Safari: p(code)=13px
These should all be 16px = 1.6 * 10px
body { font-size: 62.5%; }
code { font-size: 1.6em; }
<p>paragraph <code>p(code)</code></p>
With html { font-size: 62.5%; } and code { font-size: 1.6rem; } we have:
p=10px
FireFox: p(code)=16px
Chrome: p(code)=13px
Safari: p(code)=13px
FireFox is the only browser to get it right here.
html { font-size: 62.5%; }
code { font-size: 1.6rem; }
<p>paragraph <code>p(code)</code></p>
I suspect this all doesn't matter much because people are used to slapping font-size styles all over the place in their CSS.
From my reading, there has been an attempt to make web pages more responsive to the native settings on each device: to adapt to varying hardware with more or fewer pixels per inch (PPI); to allow users with reduced vision to request larger text so they can read more easily; etc.
There are various recommendations and a bit of controversy about how to best do this: specify font-size with html { font-size: 62.5% } and use em or rem everywhere seems to be a popular opinion. Lately just using good old px to specify font-size is coming back in style, with the idea that px does not specify actual screen pixels but rather an idealized 96 dpi for the viewer (which may translate to a different number of pixels) and letting the browser's zoom controls handle user desired changes in font-size.
In summary, I think these problems with font size argue against the logic behind most of the advice about "responsive design" for font size. My guess is that this is an area where there is a lot of history factored into how browsers work, and it's near impossible to change now. And of course there are millions of websites with existing code that are all presumably happy with how font sizing is working now.
It seems to me that the only way to get consistent font sizing is to use pixels: px. For example, px at the Root, rem for Components, em for Text Elements. Or just just use pixels everywhere.
Mozilla writes the following about accessibility and font-size
Defining font sizes in pixel is not accessible, because the user cannot change the font size from the browser. (For example, users with limited vision may wish to set the font size much larger than the size chosen by a web designer.) Therefore, avoid using pixels for font sizes if you wish to create an inclusive design.
But with all these bugs with inherited and relative font size it doesn't seem like an option to avoid using pixels. Plus the argument about a reference pixel and using the browser's zoom control seems to solve the accessibility issue.
That's because back in the dark ages one Netscape dev decided to force his personal preferences on everyone else in the browser settings (most coders are young people who think it is smart to destroy their eyes by setting text size one or two sizes smaller than everyone else, they think "monospace" belong to them and "sans serif" to normal human beings).
Thus, Firefox ships with defaults that alias "monospace" to a smaller font size than "sans serif". Pretty much destroys coordinated font sets (where the monospace font is designed to look the same as the serif or sans serif one).
You can "fix" it locally by launching about:config and changing all font.size.fixed.* properties to the same value as font.size.variable.* ones. But since you can't fix all Firefoxes in the wild, that makes the monospace css alias useless for this browser.
Response from OP moved from question to answer:
The answer from BoltClock was super helpful. The page he/she referenced about Fixed Monospace Sizing by Eric Meyer has a thorough analysis and some solutions. It explains some of the browser mechanics related to when the user's font preferences are used, which explains some of the mysterious behavior I was seeing (e.g. why was the code element seeming to inherit a size of 13px when it was the child of a p element with size of 16px: the reason is it actually inherits size medium which causes the browser to use the default browser/user preferences).
For my situation I'm finding I can remove the html { font-size: 16px; } style and instead add the following:
pre { font-family: monospace, monospace; }
code { font-family: monospace, monospace; font-size: 100%; }
This gives me consistent relative font-sizing but still allows the user to set the default font-size. Eric Meyer recommends using monospace, serif but I'm finding that monospace, monospace works, and I think it makes a little more sense when you see it in a style-sheet (it's odd, but looks probably intentional, and it means you really, really want monospace).
I think that the ultimate problem is that the browsers have different font-size defaults/preferences for monospace font, than for other fonts. The main idea of "accessible responsive design" in regards to font-size is to let the user have control over font-size. But when we have several settings for font size (serif, sans-serif, monospace) then that's too many options for the user to set. The user just wants bigger text that they can read. But for the author: they just want the relative sizes of the fonts to be correct at whatever given size.
In case it's helpful to someone else, here are some examples (in the slick Eric Meyer style) showing that monospace, monospace fixes some of the problems I wrote about in my own answer below.
code:before {
content: attr(style);
border-bottom: 1px solid #AAA;
color: #575; margin-right: 0.5em;
}
p {
margin-bottom: 2em;
}
<p>This is a 'p' element with a <code>'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace, monospace">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-size: 100%">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace; font-size: 100%">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace, monospace; font-size: 100%">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace; font-size: 120%">'code' element</code> contained within.</p>
<p>This is a 'p' element with a <code style="font-family: monospace, monospace; font-size: 120%">'code' element</code> contained within.</p>
I came across a similar issue where I used monospace and the sizes were different in Google Chrome and Edge & Mozilla Firefox. This is because different browsers have different font weights and sizes for standard fonts.
To resolve this issue I used Google fonts and then the fonts sizes were the same in all browsers.
I want to put tags around a some text without changing whatever font family and font size the text has already inherited. I could redefine the CSS for h1 so that nothing is said about the font-family or font-size but then the values from the user agent would just come through. I need to define the CSS for h1 in a way that the user agent values are killed, something like
h1{
font-family:none;
font-size:none;
}
But I don't think that will work.
Thanks
Just use the inherit keyword.
font-family: inherit;
font-size: inherit;
I can't think of a good reason for making the most important heading in your document indistinguishable from body text though. It runs the risk of being treated as a spam flag by search engines.
Please use inherit, this will work, which will inherit your parent style
font-family: inherit
Font size is simple:
h1 { font-size: 100%; }
Font family is trickier, and the most robust way is to declare the font family h1 and its parent together. Assuming that h1 is a child of body, you could use
body, h1 { font-family: Helvetica, Arial, sans-serif; }
These settings, like any settings you might set, are ineffective against user style sheet rules that override them, as well as against browser defaults when the browser has been configured to ignore font sizes and/or families specified on web pages.
However, they work wider than the use of inherit, which is not recognized by some old browsers.
I'm using #font-face that has to be given a large font-size. for example the font-size of the title is 54px which is normally so big, but in this font it appears medium.
So the problem is, while the page loads, the alternative font appears veeeery big and breaks the whole layout.
Is there a way i can specify a font-size for alternative font?
You might be able to use Modernizr. It adds classes to the <html> element which represent features that the browser supports. In this case, the class it adds for #font-face support is fontface.
What I would do is set the title size to what looks good for the alternative font, then nest the proper font-size, like so:
.title {
font-size: 20px;
font-family: arial, sans-serif;
}
.fontface .title {
font-size: 50px;
font-family: 'alternative-font', arial, sans-serif;
}
Though, even then I guess it might not change in the right order... Generally, I'd not worry about the layout looking funny while loading, but hopefully this helps.
I would try to retrieve the name of the font being used via JavaScript or jQuery and if it's not the #font-face font then adjust the font-size accordingly.
Edit:
Here's a JavaScript Font Detection plugin to test when the fallback font is being rendered.
