The font size h is a defined value. Font types and sizes

The font size on the site can be set using both HTML and CSS. Let's consider both options.

Setting font size with HTML

The font size on the page can be determined using the tag font HTML. In the article, we have already considered the tag font and its attributes. One of the attributes of this tag is size, which allows you to set the font size. It is applied as follows:

Website builder "Nubex"

size can take values ​​from 1 to 7 (the default is 3, which corresponds to 13.5 points for the Times New Roman font). Another option for setting the attribute is “+1” or “-1”. This means that the size will be changed relative to the base one by 1 point more or less, respectively.

The above method is quite easy to use and is indispensable if you need to change the font size of a small piece of text. In other cases, it is recommended to style the text using CSS.

Setting the font size with CSS

In CSS, a property is used to change the font size font-size, which is applied as follows:

In the example above, the font size is set in pixels. But there are other ways to set the size:

• large, small, medium- set the absolute size (small, medium, large). Extra-small (x-small, xx-small), extra-large (x-large, xx-large) values ​​can also be used.
• larger, smaller- set the relative size (less or more relative to the parent element).
• 100% - the relative size is set (as a percentage relative to the parent). For example: h1 ( font-size: 180%; ) This means that the size of the tag H1 will be 180% of the base font size.
• Other options for setting relative size:
  • 5ex- means that the size will be 5 letter heights x from the base font;
  • 14pt- 14 points;
  • 22px- 22 pixels;
  • 1vw- 1% of the width of the browser window;
  • 1vh- 1% of the height of the browser window;

Under a concept such as font”, is understood graphic image drawing elements such as letters and numbers. This word is of German origin and literal translation means handwriting or inscription, as well as its meaning, which is usually used in everyday life.

The norms and rules for the preparation of technical documents and their design establish that they should use only the font that has certain standard sizes. His hallmarks are rigor and legibility, which should be such as not to impede readability. The outlines of technical fonts are always straight, and therefore they belong to the class that does not imply the presence of any serifs, and for this reason, they are most convenient for visual perception and reading. The technical font is applied in such a way that, with respect to the base of the line, it is located at an angle of about 75 degrees. At the same time, the current rules and regulations allow the use fonts and no slope.

Current to date GOST 2.304 - 81 says that ten sizes are provided for the drawing font, namely: 1,8 ; 2,5 ; 3,5 ; 5 ; 7 ; 10 ; 14 ; 20 ; 28 ; 40 . In this case, the size means the value that determines the height of the capital (capital) letter. In this case, it is measured in relation to the base of the line, perpendicular to it. This setting font denoted by the letter ( h) and is its size. As for letters like SCH, C, D, then their lower elements, as well as the upper element of the letter Y performed by spacing between lines.
	The thickness of the lines is also one of those parameters that has drawing font. The thickness of the lines is indicated by the letter ( d), and its size is 0.1h. .
letter ( g) is the width of capital letters, and it is equal to 6d or 0.6h, and this size approximately corresponds to the value ( h), which has font nearest lowest number. This rule does not apply to letters such as YU, S, C, X, M, D, BUT. Their width is 0.7d. In addition, the exception also applies to letters Kommersant, W, SCH, F, AND, for which this parameter is 0.8d, as well as letters FROM, Z and G whose width is equal 0.5d.
	For the vast majority of lowercase letters, the parameter ( With), denoting their height, is equal to 0.7h. This size is approximately equal to that of font the nearest lowest number. For example, for the font that has the number 10 , the lowercase letter will be the height 7 millimeters, and the same parameter for a lowercase letter number 7 – 5 millimeters. As for the bottom and top elements that have lowercase letters, they are sized 3d, which is done by spacing between strings.
The width of lowercase letters is indicated by the symbol ( g), and its value is equal to 5d. Letters are an exception. a, m, c, b whose width is equal 6d; for letters h,With– 4d; and for letters and, t, f, sh, sch, s, Yu – 7d.
	A special helper grid has been developed to help beginner draftsmen learn how to apply font manually. It is formed by thin auxiliary lines, between which letters must be entered. The step that the auxiliary grid lines have depends on the value of the parameter ( d) (that is, the thickness of the lines of the font itself).

Font Options Table

The table summarizes such font parameters as the height, thickness and width of its lines, as well as the minimum distance that should be between words and between letters.

Font options	Designation	Relative size	Size in mm
			3.5	5	7	10	14
Capital letters height	h		3.5	5	7	10	14
	c	0.7h	2.5	3.5	5	7	10
Letter spacing	a	0.2h	0.7	1.0	1.4	2.0	2.8
Minimum distance between line bases	b	1.7h	6.0	8.5	12.0	17.0	24.0
Minimum spacing between words	e	0.6h	2.1	3.0	4.2	6.0	8.4
	d	0.1h	0.35	0.5	0.7	1.0	1.4

The graphical representation of letters and other characters is called a font. All together they represent a single stylistic and compositional system, which is designed to display information visually.

More plain language, font is a set of numbers, letters and special characters, which are uniform in terms of style and are performed with strict observance of the proportions between their sizes.

Parameters such as size (size), width (wide, narrow, normal), weight (bold, bold, light), style (italic, upright) are the main characteristics of fonts.

Additional font characteristics include readability, capacity, contrast, legibility, and legibility. They are also of great importance.

5. EDITION (August 2007) with Amendment No. 1, approved in March 1989, June 2006 (IUS 7-89, 9-2006)

This International Standard establishes drawing fonts applied to drawings and other technical documents of all industries and construction.

1. TERMS AND DEFINITIONS

1. TERMS AND DEFINITIONS

1.1. Font size- the value determined by the height of capital letters in millimeters.

1.2. The height of capital letters is measured perpendicular to the base of the line.

The height of lowercase letters is determined from the ratio of their height (without processes) to the font size, for example, = 7/10 (Fig. 1 and 2).

1.3. Letter width- the largest letter width, measured in accordance with drawings 1 and 2, is determined in relation to the font size, for example, 6/10, or in relation to the thickness of the font line, for example, 6

1.4. Font Line Thickness- thickness, determined depending on the type and height of the font.

1.5. Auxiliary grid- a grid formed by auxiliary lines into which letters fit. Step auxiliary lines the grid is determined depending on the thickness of the font lines (Fig. 3).

Notes:

1. The distance between letters whose adjacent lines are not parallel to each other (for example, GA, AT) can be halved, i.e. on the line thickness of the font.

2. Minimum Distance between words separated by a punctuation mark is the distance between the punctuation mark and the word following it.

When executing documents in an automated way, it is allowed to use fonts used by means of computer science. In this case, their storage and transfer to users of documents should be ensured.
