<p style="line-height: 16px; font-size: 12px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);"> CSS was started in HTML 4 and was introduced for better rendering of HTML elements .

<p style="line-height: 16px; font-size: 12px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);"> CSS can be added to HTML in the following ways:

<ul style="line-height: 16px; font-size: 12px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);" class=" list-paddingleft-2"> Inline styles - use the "style" attribute

# in an HTML element ## Internal style sheet - use the element ## in the HTML document head head > area #To include CSS

External References - Use external CSS File

The best way is to reference the CSS file externally. <p style="line-height: 16px; font-size: 12px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);">

Inline styles

<h2 style="font-size: 22px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; margin-top: 10px; margin-bottom: 10px; font-weight: bold; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); font-style: normal; font-variant: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"> Inline styles are used when special styles need to be applied to individual elements. The way to use inline styles is to use the style attribute in the relevant tag. Style properties can contain any CSS property. The following example shows how to change the color and left margin<p style="line-height: 16px; font-size: 12px; font-family: 'Microsoft Yahei', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);"> of a paragraph. <p style="color:blue;

margin-left :20px;">This is a paragraph.

Internal style sheet Internal style sheets are used when a single file requires special styling. You can define internal style sheets via the tag in the section:

body {background-color:yellow;} p {color:blue;}

External style sheet External style sheets are ideal when styles need to be applied to many pages. Using external style sheets, you can change the look of your entire site by changing one file.
