I am unable to find how to implement line-Height in QML TextArea.
Since in Text item we have the property of line-height and lineHeightMode and suppose I have line-height of 22px then how to implement it in TextArea item which is further present in a Rectangle of fixed height and width (78 and 288 resp.).

How to calculate the height of an inline element

As you can see, the content of inline item (<span>) are inside green box.My question is where is height of the box from .
Firstly it is not the height property which is not applicable to inline at all.
Secondly ,it is not line-height as well ,the only thing it affect is that space between the boxes.
So, where is the height from?
it's just the font-size (and height), including the space for the ascenders and descenders of letters like j, Q, p T F etc. (which can be different for every font)
line-height:normal is the default, which is about 1.2xfont-size for the major browsers. Look in the Computed Style tab.
On non-replaced inline elements, line-height specifies the height that is used to calculate line box height.
See https://developer.mozilla.org/en-US/docs/Web/CSS/line-height
That span is a non-replaced inline element and it's height defaulted to auto (which is irrelevant, since height doesn't apply to it unless it was anything but inline) it defers to line-height of about 1.2.
In the case of a line which contains only inline non-replaced elements which are all the same font-size and line-height, and all of which have the same vertical alignment, the solution is simple. The content-area is defined by the font-size of the elements, and the height of the line-box is equal to the value of line-height.

Sorry, 16px x 1.2 = 19.2px
From the conversation in comments, I understand your question is how the height of the green box/area is being calculated.
This area is not calculated by either height or line-height attributes. This area is, without any padding, the minimum area which covers all the letters in the span element - which is actually the font-size of your text.
Adding a border or padding to the span, it will make the green area bigger by that size.
This html/css:
Left
Produces this:
But I want this:

ThisWontBeVisible
The class ui-btn-icon-notext will remove the text ("ThisWontBeVisible") within the <a>. However, if there is no text within the <a>, it will shrink the button to a short height. Seems like a hack but also likely the simplest way to achieve the desired result.
You can do it by setting the height attribute to 1em on all of your .ui-btn elements, or any height greated than 1em. This will set them all to the same height regardless of whether they have text inside them or not.
I have some <h1> and <p> tags with text content. I'd like the top of the text (cap height) and the bottom of the text (baseline) to be flush with the tag's bounding block. By default there seems to be a certain amount of spacing and I don't know why. Is there a calculation to determine this spacing?
I can achieve what I'm after if I modify the line-height and the height properties of the element, but then the original and desirable line-height for multi-line text overlaps and isn't what we want.
Ex. Right-click a <p> tag on this page and hover the element in the dev console to notice that the top/bottom of the text isn't flush with the bounds of the actual <p> element.
Is it possible to make the cap height and baseline flush with and
element's bounds?
Is this spacing possible to edit in CSS?
Is there a rule/calculation that determines what this spacing is?
you want to use something called css reset block
http://html5doctor.com/html-5-reset-stylesheet/
and also if your container is a div
use display:inline; to wrap exactly onto the element inside.
I have a div element that covers the whole width of the window and a label inside of it. The label gets changed dynamically and sometimes the text inside it goes beyond the boundaries of the div. There is an example:
http://jsfiddle.net/VWNKC/
I tried with the:
white-space: nowrap
on both div and label but it just didn't work.
I am just wondering if it is possible to shrink the text inside the label so it fits the width of the parent div.
You can see that the label goes beyond the div if you scroll and try to select something after the end of the blue background of the div. There is still content.
EDIT:
I am not trying to shrink the text but to show parts of its content, Lets say the beggining of the text. I am not trying to change the size of the font, I just want to show the part of the text that fits inside the div.
It seems you want the label to wrap inside the parent container?
In that case white-space: nowrap will not work, that will just cause the label text to go beyond the parent container's boundary without wrapping to the next line.
So there are two ways you could do this, either have the text wrap to the next line so that the label remains within the width of the div, or have it gracefully truncate by using the following CSS Properties:
text-overflow: ellipsis;
overflow: hidden;
Is there any kind of property or a CSS solution that scales your text depending on the parent dimensions. So that text will not get out of content regardless of parent size ?
I have a div where I add my text. This div is dynamically shkrinked and when this is done the text is displayed outside the div.
