What is a style sheet?
CSS is abbreviated by the cascading style sheet. Translated "laminated style form". Is a marker language for (enhanced) control web page styles and allows styles information to separate from web content.
How to add a style sheet to your page
You can use the following three ways to add a style sheet to your web page. The higher the priority of the most closely targets. High-priority patterns will inherit undequited definitions of low priority patterns but overlaid. Please refer to exception
Important declaration.
Link to the external style sheet file (Linking to a style sheet)
You can build an external style sheet file (.css) and then use the HTML LINK object. Examples are as follows:
title of articles </ title></p>
<p><link rel = stylesheet href = "http://www.dhtmlet.com/rainer.css" type = "text / css"></p>
<p></ hEAD></p>
<p>In XML, you should join in the declaration area as shown in the following example:</p>
<p><? xml-stylesheet type = "text / css" href = "http://www.dhtmlet.com/rainer.css"? >></p>
<p>Define internal style block objects (Embedding a style block)</p>
<p>You can insert a <style> ... </ style> block object between your HTML document <HTML>, and <BODY> tag. Please refer to the definition method</p>
<p>Style formula syntax. Examples are as follows:</p>
<p><html></p>
<p><style type = "text / css"></p>
<p><! -</p>
<p>Body {font: 10pt "arial"}</p>
<p>H1 {font: 15pt / 17pt "arial"; font-weight: bold; color: maroon}</p>
<p>H2 {font: 13pt / 15pt "arial"; font-weight: bold; color: blue}</p>
<p>P {font: 10pt / 12pt "arial"; color: black}</p>
<p>-></p>
<p></ style></p>
<p><body></p>
<p>Note that the Type property of the Style object is set to "Text / CSS" here, which is allowed to support this type of browser ignore style form.</p>
<p>Inline STYLES</p>
<p>Inline definition is the style table property that applies it to the style attribute of the object in the object's tag. Examples are as follows:</p>
<p><p style = "margin-left: 0.5in; margin-right: 0.5in"> This line has been added to the left and right external patch <P></p>
<p>Style formula syntax (CSS Syntax)</p>
<p>Selector {Property: value}</p>
<p>Parameter Description:</p>
<p>SELECTOR -</p>
<p>Select</p>
<p>Property: Value - Style Table Definition.</p>
<p>The attribute and attribute value are separated by a colon (:). Sepailed between the definitions (;)</p>
<p>Inherited value (The 'Inherit' Value)</p>
<p>Each attribute has a specified value: inherit. It means: the value of the parent object is equivalent to the computer. This value is usually just alternate. Explicit statement it can be used to emphasize.</p></div><div class="text-center mt-3 text-grey">
