I'm trying to achieve the equivalent of (I know it is not actually permitted in CSS) :
{padding-top : -3x }
In this original fiddle you can see that I want my h2 content to be aligned with the very top and bottom of the enclosing block element.
My -ve margin-left works, but a -ve margin-top moves the enclosing element upwards (taking the h2 with it). What I want is for the white letters to bleed into the background, so I need to be able to move the text to the top of the enclosing block element and reliably to set the vertical height of the <header> so that the bottom edge also bleeds into the background. So far it is very trial-and-error which I suspect will mean that it fails on other browsers, but I can't find any css options that do a better job.
Based on the first two first two answers, I have updated the fiddle, but I'm still left with the 3em font and 2.05em line-height for the container (and having heard that you should not generally add units to line height as well, which would lead me toward a line height of 0.7) and wondering whether that is a robust relationship (and if so how is it expressed mathematically) across all situations including mobile phones?
Why not just use a San-Serif font like Arial.. see Fiddle
#experience {
background-color: black;
position: relative;
margin: 0em 0;
line-height: 2.05em;
}
#experience h2 {
color: white;
text-transform: uppercase;
margin-left: -5px;
font-family: "Arial";
font-weight: bold;
font-size: 3em;
letter-spacing: 0.1em;
}

I have this code:
<p style="line-height: 1;overflow: hidden;">blah_blah</p>
<p>blah_blah</p>
<p style="line-height: 1;overflow: hidden;">qypj;,</p>
<p>qypj;,</p>
which results in (notice no underscore, and cut characters):
That is, it behaves that way in Firefox (66.0.3 on Windows 10). Other browsers seem to render the underscore. The above snippet runner also seems to work (even in Firefox), unless you run it in "Full page".
This Q is similar to Text changes height after adding unicode character except there are no tricks here. "_" is just a simple ASCII character.
My question is which behavior is the correct one.
Is specific character allowed to change line height (I thought it was only supposed to be font dependent)? Shouldn't line-height: 1 imply it can fit exactly any text?
I suppose some characters are special, such as "p", "g", "j" (and possibly "_") that draw below its line. Still which behavior is the correct one. Is it considered overflow or not?
PS: Furthermore I find it funny either overflow-x: hidden;overflow-y: visible; and overflow-x: visible;overflow-y: hidden; still causes this. Which seems more like an actual bug to me.
My question is which behavior is the correct one.
All of them are correct because we don't have the same default font in all browsers and it's also different depending on the OS.
Is specific character allowed to change line height (I thought it was only supposed to be font dependent)?
Character doesn't change line-height. To be more accurate, line-height is a property that can only be changed by setting line-height but you are probably confusing with the line box that is defined by the line-height and a character alone cannot change it.
Shouldn't line-height: 1 imply it can fit exactly any text?
Not necessarely, line-height:1 means that the line box will be equal to the 1xfont-size 1 but is the font designed to include all the character inside this space? Probably most of them will do but we don't know.
Basically, you have two things to consider. The content area that is defined by the font properties and the line box that is defined by the line-height. We have no control over the first one and we can only control the second one.
Here is a basic example to illustrate:
span {
background:red;
color:#fff;
font-size:20px;
font-family:monospace;
}
body {
margin:10px 0;
border-top:1px solid;
border-bottom:1px solid;
animation:change 2s linear infinite alternate;
}
#keyframes change {
from {
line-height:0.2
}
to {
line-height:2
}
}
<span >
blah_blah
</span>
The red is our content area and its height is defined by the font properties and if you inspect the element you will see it has a height equal to 23px (not 20px like the font-size) and the borders define our line box that we control using the line-height.
So if the line-height is equal to 1 we will have a line box equal to 20px which is not enough to contain the 23px of the content area thus it will get truncated and we may probably hide some characters (or a part of them) which is logical:
span {
background: red;
color: #fff;
font-size: 20px;
font-family: monospace;
}
body {
margin: 5px;
line-height: 1;
overflow:hidden;
}
html {
overflow:auto;
}
<span>
blah_blah ÂÄ j p
</span>
a different font-size will remove the underscore in Firefox:
span {
background: red;
color: #fff;
font-size: 26px;
font-family: monospace;
}
body {
margin: 5px;
line-height: 1;
overflow:hidden;
}
html {
overflow:auto;
}
<span>
blah_blah ÂÄ j p
</span>
Another example with a Google Font where the result should be the same cross browser. The underscore is visible but not the ^/¨
span {
background: red;
color: #fff;
font-size: 26px;
font-family: 'Gugi', cursive;
}
body {
margin: 5px;
line-height: 1;
overflow:hidden;
}
html {
overflow:auto;
}
<link href="https://fonts.googleapis.com/css?family=Gugi" rel="stylesheet">
<span>
blah_blah ÂÄ j p
</span>
Another example where the underscore is not visible:
span {
background: red;
color: #fff;
font-size: 27px;
font-family: 'PT Sans', sans-serif;
}
body {
margin: 5px;
line-height: 1;
overflow:hidden;
}
html {
overflow:auto;
}
<link href="https://fonts.googleapis.com/css?family=PT+Sans" rel="stylesheet">
<span>
blah_blah ÂÄ j p
</span>
You can clearly see that we have a different overflow everytime we use a different font which confirms that this is font related. We have no control over it unless we know how the font is designed.

Line height issue with inline-block elements
Here is a good article to get more accurate details and calculation: https://iamvdo.me/en/blog/css-font-metrics-line-height-and-vertical-align
A quote from this article:
It becomes obvious that setting line-height: 1 is a bad practice. I remind you that unitless values are font-size relative, not content-area relative, and dealing with a virtual-area smaller than the content-area is the origin of many of our problems.
1 : I considered a simplified explanation but in reality the calculation of the line box is not only relate to the line-height property.
The default line-height (depending on the font-family) when not otherwise specified is about 1.2 in most browsers. This includes Firefox.
This would explain why the underscore did not show in FireFox when the line-height was set to 1 - the bottom was of the line was cut off. So I don't think it's entirely to do with the font (although this does contribute), but also browser defaults.
Some font-sizes are bigger than other even at seemingly the "same" font size (as I'm sure you've seen when typing documents in e.g. Georgia vs Times new Roman/Baskerville ; so you wouldn't be guaranteed that text would always show on a specified line height of 1 (or 1.2). There are ways of measuring a font in pixels however
Hope this helps
If I use the browser tools in Firefox to inspect my snippet below, there is no height difference between the lines with and without underscore. The only difference is caused by the line-height setting: 16px with line-height: 1, 19.2 px with the browser's default line-height. So the underscore doesn't make a difference here (Firefox 66.0.3 on Mac), and it is visible in both cases.
Note that I set margins to 0 to see the "pure" line-height without distances between the lines. Also, I didn't specify a font-familiy setting, so the default font of the browser for p tags is used.
The only reason for what you describe which I can think of is a font with very particular dimensions/settings, where the descenders (i.e. the parts of letters like p q j which extend below the baseline) are not inside the line-height as defined by the font.
After a bunch of comments back and forth: I suppose it could be caused by the different default (system) fonts on Windows and Mac. Still a bug, I would say (if you are using the default font).

This is my problem in short: https://jsfiddle.net/b6wLwkfs/
Long story: I have a div with some text in it. It initially creates some space on top and bottom of my div (this is not padding). I would like my div to only cover the text and not create extra space. This is my only css:
div {
background-color: black;
color: white;
font-size: 50px
}
<div>This is the text</div>
What I am looking for is to narrow down the div to only contains the text without creating any space on top of bottom. I acknowledge that if you tweaking a bit with px, you will achieve that but I am looking for more generic approach since font size will be different by cases.
Your code below is missing a (;) after font-size: 50px; now to achieve the space reduction I suggest you use line-height with the same font-size refer to my correction
Your Code
div {
background-color: black;
color: white;
font-size: 50px
}
My Correction
div {
background-color: black;
color: white;
font-size: 50px;
line-height: 50px;
}
There is likely no 'generic' way to do this, as that spacing you're seeing is actually part of the font face, and whatever adjustments you make to solve the 'problem' for this font, will not necessarily work on other fonts.
For example, just take a look at how Arial displays, as it's different than the default font that is used without setting a specific font-family, and as such a fix for the default font would likely have to be adjusted for Arial.
p {
background-color: black;
color: white;
font-size: 50px;
line-height: 1;
font-family: arial;
display: inline;
}
<p>
Oh hi i'm different
</p>
In the above snippet I've added a line-height of 1 to help normalize the spacing a bit. You could try to adjust further with setting the line-height to be at, or close to the exact font-size in pixels, but this will likely result in undesired spacing if you have lots of text in the element (text should also be in an appropriately semantic element like a p, or li, not just in a div).
In the end, can you achieve the result you're looking for? Definitely. Using things like line-height, margins and/or transforms. But you are likely not going to find a silver bullet to achieve the effect you want, consistently, if swapping out font faces.
As Sebastian Brosch mentioned in the question's comments, working off from Is it possible to change inline text height, not just the line-height? is likely going to be your best path forward.
I want the text to be perfectly aligned to the picture. But the text has some room on each side. This is supposed to be shown on different devices so just hardcoding like top : -3 px won't work.
Is there any way to make the text snap to the top of the div.

top:-3px won't work because it deals with positioning. More than likely you probably need to use padding-top:-3px;. If that doesn't, we'd need to see code because it is impossible to answer by looking at a picture
Try
line-height: 0
And adjust the margin-top: value.
Or a lower line-height value. (e.g., 1em line-height would be relative to the font-size as 1:1em)
Sicking to px in this scenario is your best bet for cross browser consistency.
Without code, it's going to be hard to identify the exact issue, but lets give it a shot.
All text has something called line-height which is the amount of space from the top of the font to the bottom of the font. Most fonts build in padding along the top to make multiple lines of text readable. CSS allows us to adjust that.
p {
line-height: 14px;
}
This code will tell all <p> elements to have a total line-height of 14px. If your font is taller than 14px it will overlap.
If this doesn't fix your problem, then the issue probably has to do with the margin/padding.
Try:
.medium-title {
font-size: 17px;
line-height: 0.8;
}

Say I have a single span element defined as an inline-block. It's only contents is plain text. When the font size is very large, you can clearly see how the browser adds a little padding above and below the text.
HTML:
CSS:
span {
display: inline-block;
font-size: 50px;
background-color: green;
}
<span>BIG TEXT</span>
Looking at the box model, it's clear the browser is adding padding inside the content edge. I need to remove this "padding", one way is to simply alter the line-height, as with:
http://jsfiddle.net/7vNpJ/1/
This works great in Chrome but in Firefox the text is shifting towards the top (FF17, Chrome 23, Mac OSX).
Any idea of a cross-browser solution? Thanks!
It appears as though you need to explicitly set a font, and change the line-height and height as needed. Assuming 'Times New Roman' is your browser's default font:
span {
display: inline-block;
font-size: 50px;
background-color: green;
/*new:*/
font-family: 'Times New Roman';
line-height: 34px;
height: 35px;
}
<span>
BIG TEXT
</span>
The browser is not adding any padding. Instead, letters (even uppercase letters) are generally considerably smaller in the vertical direction than the height of the font, not to mention the line height, which is typically by default about 1.2 times the font height (font size).
There is no general solution to this because fonts are different. Even for fixed font size, the height of a letter varies by font. And uppercase letters need not have the same height in a font.
Practical solutions can be found by experimentation, but they are unavoidably font-dependent. You will need to set the line height essentially smaller than the font size. The following seems to yield the desired result in different browsers on Windows, for the Arial font:
span.foo
{
display: inline-block;
font-size: 50px;
background-color: green;
line-height: 0.75em;
font-family: Arial;
}
span.bar
{
position: relative;
bottom: -0.02em;
}
<span class=foo><span class=bar>BIG TEXT</span></span>
The nested span elements are used to displace the text vertically. Otherwise, the text sits on the baseline, and under the baseline, there is room reserved for descenders (as in letters j and y).
If you look closely (with zooming), you will notice that there is very small space above and below most letters here. I have set things so that the letter “G” fits in. It extends vertically a bit farther than other uppercase letters because that way the letters look similar in height. There are similar issues with other letters, like “O”. And you need to tune the settings if you’ll need the letter “Q” since it has a descender that extends a bit below the baseline (in Arial). And of course, if you’ll ever need “É”, or almost any diacritic mark, you’re in trouble.
I'm a designer and our devs had this issue when dealing with Android initially, and our web devs are having the same problem. We found that the spacing between a line of text and another object (either a component like a button, or a separate line of text) that a design program spits out is incorrect. This is because the design program isn't accounting for diacritics when it is defining the "size" of a single line of text.
We ended up adding Êg to every line of text and manually creating spacers (little blue rectangles) that act as the "measurement" from the actual top of the text (ie, the top of the accent mark on the E) or from the descender (the bottom of a "g").
For example, say you have a really boring top navigation that is just a rectangle, and a headline beneath it. The design program will say that the space between the bottom of the top nav and the top of the headline textbox 24px. However, when you measure from the bottom of the nav to the top of an Ê accent mark, the spacing is actually 20px.
While I realize that this isn't a code solution, it should help explain the discrepancies between the design specs and what the build looks like.

span::after {

Find out the margin-top and margin-bottom negative margins with this tool:
http://text-crop.eightshapes.com/
The tool also gives you SCSS, LESS and Stylus examples.
You can read more about it here:
https://medium.com/eightshapes-llc/cropping-away-negative-impacts-of-line-height-84d744e016ce
I had a similar problem. As you increase the line-height the space above the text increases. It's not padding but it will affect the vertical space between content. I found that adding a negative top margin seemed to do the trick. It had to be done for all of the different instances of line-height and it varies with font-family too.
Maybe this is something which designers need to be more aware of when passing design requirements (?)
So for a particular instance of font-family and line-height:
h1 {
font-family: 'Garamond Premier Pro Regular';
font-size: 24px;
color: #001230;
line-height: 29px;
margin-top: -5px; /* CORRECTION FOR LINE-HEIGHT */
}
This worked for me:
line-height: 80%;
If its text that has to scale proportionally to the screenwidth, you can also use the font as an svg, you can just export it from something like illustrator.
I had to do this in my case, because I wanted to align the top of left and right border with the font's top |TEXT| . Using line-height, the text will jump up and down when scaling the window.
The best way is to use display:
inline-block;
and
overflow: hidden;
I've been annoyed by this problem often. Vertical-align would only work on bottom and center, but never top! :-(
It seems I may have stumbled on a solution that works for both table elements and free paragraph elements. I hope we are at least talking similar problem here.
CSS:
p {
font-family: "Times New Roman", Times, serif;
font-size: 15px;
background: #FFFFFF;
margin: 0
margin-top: 3px;

}
For me, the margin settings sorted it out no matter where I put my "p>.../p>" code.
Hope this helps...
I am currently designing a web page with em units. I guess I don't understand it as well as I thought I did because a problem has occurred while I tried to align two separate span tags with margin-left. They were placed in the upper-left corner of my header. They were positioned on top of one another using display:block. When I used margin-right to align both the span tags, the larger span and the smaller tag didn't align correctly. I used the same number for margin-right, but they were still messed up.
Is this because I'm using em's?
How can I fix this?
I will paste the code I'm using below so you'll get a sense of what I'm working with. Hopefully I've explained this well enough.
HTML
<div class="header1">
<span class="title">Title goes here</span>
<span class="subtitle">This is the subtitle</span>
</div>
CSS
body {
color: #333;
font-family: 'lucida grande', tahoma, verdana, arial, sans-serif;
font-size: 62.5%; /* 10px */
line-height: 1.28;
}
.main1 {
width: 96em;
/* horizontally center the website layout */
margin: 0 auto; margin-top: .8em;
text-Align: left; /* override body {text-align:center} */
}
div.header1 {
clear: both;
width: 100%;
height: 9em;
background: #ff0000;
color: #fff;
}
.title {
font: small-caps 700 3.7em "Goudy Old Style", Garamond, "Big Caslon", "Times New Roman", serif;
}
.subtitle {
font-weight: lighter;
font-size: 1.4em;
}
The description of the problem is very confusing and does not explain what you want to achieve and what is your best attempt at that. You refer to left and right margin, but neither of them is set in your code for the elements discussed. You refer to setting display: block, but there is no such setting.
I will assume that you want the main title to appear (in the xy plane) above the subtitle. For this you need to set display: block or, better, use div markup instead of span or, best, use adequate heading markup such as h1 and h2 with due consideration of their default effects on vertical margins and font weight (i.e., overriding them in CSS if needed). And I assume that you wanted them left-aligned the same amount.
It seems that you did not take into account the relativity of the em unit. By definition, it equals the font size of the element (except in font-size, where it equals the font size of the parent element).
I suspect that you tried setting the left margin of both span elements using the same value such as 1em. But it does not mean the same for both elements, since their em sizes differ. If you wanted to set the their left margins to, say, the font size of the first element, you would set
.title { margin-left: 1em; }
.subtitle { margin-left: 2.6429em; }
The number 2.6429 is the ratio of the font sizes, calculated from 3.7/1.4.
It would be easier to just set a left margin on the enclosing div element. Its font size equals the font size of the body element, so if you wanted to set it to the font size of the main heading, you would use
div.header1 { margin-left: 3.7em; }
check the bellow link I hope this will help for you
http://kyleschaeffer.com/best-practices/css-font-size-em-vs-px-vs-pt-vs/
px: pixels (a dot on the computer screen)
em: 1em is equal to the current font size. 2em means 2 times the size of the current font. E.g., if an element is displayed with a font of 12 pt, then '2em' is 24 pt. The 'em' is a very useful unit in CSS, since it can adapt automatically to the font that the reader uses.
see the reference
So, you can use px instead em, its good practice.
Hope it will helps you. Thanks. !!
