Html is - how to make text uppercase css. Making upper case in css How to make superscript font in html

CSS allows for flexible customization of text, which is presented using the HMTL language. Today we will look at the effect of the “text-transform” property, which makes it possible to change the font case. This option is supported by all modern browsers and is included in the specification of all versions of CSS.

Purpose

The “text-transform” property can take three main values ​​and two additional ones. For example, you can assign upper case to all selected text. Or you can give the command the opposite of the previous property, where all characters become lowercase. You can make an appointment using any method convenient for you. For example, using inline styles. Or you can create

A separate file with a description of all properties. Which assignment method to use is up to you. "Text-transform" can take the following values:

  • Uppercase. Makes all selected characters capitalize. Uppercase is common in CSS because this value helps solve many problems. complex tasks related to the text.
  • Lowercase. This property is completely opposite to the uppercase command.
  • Capitalize. Changes the case of the first letter to uppercase. The remaining characters will not change.
  • None. Allows you to undo all assigned values ​​(needed to predefine a property). Usually, given value is installed by default.
  • Inherit. Inherits all properties from the parent element. It should be noted that IE does not support this property.

Application

Using CSS, uppercase (or similar effects) are set with one simple command. Therefore, there is no need to change or rewrite all the text. If we're talking about about a one-page site, then this property may not be useful. But when you control a huge portal where you need to correct the case of letters in certain fragments, then “text-transform” becomes the only effective tool. For example, you need to fix the font in the “h2” heading tags. To do this, you need to add the entry: “h2 ( text-transform: uppercase; )”, and then all second-level headings will be in upper case.

Peculiarities

Some may think that manually processing text and changing the font using the "text-transform" property makes no difference. But that's not true. If you manually change to capital letters (upper case), then when this information is copied from your site, the characters will remain unchanged. If you use CSS language, then everything happens differently. The “text-transform” property only changes the font visually for users. But in reality the symbols remain unchanged. This happens to all values ​​of this property. The copied information (text) will have the original case used in source code pages. This is the only difference between manual processing and using CSS commands.

It doesn’t matter which one you want to use - lower or upper case, the main thing is not to forget the purpose. For example, if you need changes only for decorative purposes, then you can safely use the “text-transform” property. Well, if you know that your users will probably copy the information you post, then it is best to manually change the case of all text. After all, sometimes readers do not notice such a font substitution. This is especially critical when it comes to important documents and similar information.



Convert lowercase letter to lowercase and first uppercase using CSS(8)

There is no cap clause option in CSS. Other answers suggesting text-transform: capitalize are incorrect because this option uses every word for every word .

Here rude way to do this is if you want the first letter of each element to be in uppercase, but this is definitely nowhere near the actual limits:

P ( text-transform: lowercase; ) p:first-letter ( text-transform: uppercase; )

THIS IS AN EXAMPLE SENTENCE.

THIS IS ANOTHER EXAMPLE SENTENCE.

AND THIS IS ANOTHER, BUT IT WILL BE ENTIRELY LOWERCASE. How to convert the letter UPPERCASE to lowercase and the first letter of Uppercase for each sentence as shown below, only with?

using CSS

From: THIS IS AN EXAMPLE APPLICATION.

To: This is an approximate sentence.

Update: When I use text-transform: capize; The result is still the same.

You can't do this solely with CSS. There is a text-transform attribute, but it only accepts none , capitalize uppercase , uppercase , lowercase and inherit .

If you can make all characters lowercase on the server, than you can apply:

Text-transform: capitalize

I don't think text transform will work with capital letters as input.

If you want to use for this won't work, for or textarea you need to use Javascript

function capitaliseName() ( var str = document.getElementById("name").value; document.getElementById("name").value = str.charAt(0).toUpperCase() + str.slice(1); )

which should work well for or

The index relative to the text is the displacement of characters relative to the baseline up or down. Depending on the positive or negative value of the offset, the index is called upper or lower, respectively. They are actively used in mathematics, physics, chemistry and to designate units of measurement. HTML offers two elements for creating an index: (from English superscript) - superscript and (from English subscript) - subscript. Text placed in one of these containers is designated smaller than the base text and is offset up or down relative to it. Example 1 shows how these elements and styles can be used together to change the appearance of text.

Example 1: Creating a superscript and a subscript

Superscript and subscript .formula ( font-size: 1.4em; /* Formula text size */ ) sup, sub ( font-style: italic; /* Italic */ color: red; /* Red color of characters */ ) sub ( color: blue; /* Blue color of characters */ )

Characteristic equation of a surface of the second degree

λ3 - I1λ2 + I2λ - I3 = 0

In the example, both subscript and superscript appear simultaneously. To change the index font style, styles are used that set a uniform design (Fig. 1).

Rice. 1. View of indexes after applying styles

You can refuse to use them altogether in favor of styles. An analogue of these elements is the vertical-align property, which causes the text to be shifted vertically by a specified distance. Specifically, in Example 2 the value is 0.8em for the superscript and -0.5em for the subscript. Em is a relative unit equal to the size of the current font. For example, 0.5em indicates that the text should be shifted by half the font size.

Example 2: Using Styles to Manage Indexes

Superscript and subscript .formula ( font-size: 1.6em; /* Text size */ font-style: italic; /* Italic style */ ) .sup, .sub ( font-style: normal; /* Normal style * / font-size: 0.6em; /* Index size */ color: red; /* Superscript color */ vertical-align: 0.8em; /* Shift text up */ .sub ( color: blue; /* Color subscript */ vertical-align: -0.5em; /* Move the text down */ )

f(x) = a0 + a1 x + ... + an-1 xn-1 + an xn

In the example, the formula itself is displayed in an enlarged size, the superscript symbols are set in red, and the lower ones in blue (Fig. 2).

HTML Tags and - Subscript and Superscript Text Definition and Usage

The tag defines subscript text. Sublinear text is half the height and appears below the baseline. Interlinear text can be used when writing chemical formulas, such as H 2 O.

The tag specifies superscript text. Superscript text is half the height and appears above the baseline. Superscript text can be used when writing footnotes, such as WWW.

Browser support

Tags are supported by all major browsers.

In the last video lesson we learned how to delete and add new information V new version HTML document, while reporting this search engines and highlighting visually so that visitors can also see the changes. For this, we used del and ins tags.

In this video tutorial we continue the topic of formatting text in an HTML document. We'll look at two HTML tags that indicate the superscript and subscript of text.

The sup HTML tag is the superscript of text in HTML.

An HTML tag is designed to indicate the superscript of text in HTML. In some website topics, this tag will be simply irreplaceable. For example, if you have, or are planning, a website related to any formulas, mathematical or chemical. Or, if there is a website construction topics, then the tag will be very useful and will help when designing articles, when writing formulas or any quantities, for example, square meters in construction topics.

But if your site does not relate to the listed topics, this does not mean that the tag will not be useful. It is enough to show imagination and ingenuity and find a use for this element.

HTML sub tag is a subscript of text in HTML.

As for the HTML tag, it is the opposite of the tag, and is responsible for indicating the subscript of the text. Subscript text can be used when writing formulas or mathematical equations. But besides this, perhaps you can find other uses for the tag.

The next Video Lesson is dedicated to two more tags, which in some situations can be simply irreplaceable. Moreover, they are capable of not only formatting text, for example, in an article, but also when indicating various information on the site during page layout. One of the tags carries out the translation into HTML, and the second draws a horizontal line.
