标签：21 color Color Colors HTML Setting using

HTML Colors are a way of specifying the appearance of web elements. Colors are very important aspects of web design, as they not only enhance the visual appeal but also influence user behavior. They are also used to evoke emotions and highlight important content.

In HTML, colors are generally used to color backgrounds, borders and texts.

HTML Color Coding Methods

The following three methods are mostly used to set colors in HTML:

Color Names: We can specify color names directly like green, blue or red.
HEX Color Codes: A six-digit code representing the amount of red, green, and blue that makes up the color.
RGB Color Values: This value is specified using the rgb() property.

We will learn these color coding methods in upcoming chapters.

Setting Text Color

To set the text color on text we can use the CSS color property. The value of color can be specified using any of the above discussed methods.

<!DOCTYPE html>
<html>
<head>
   <title>Setting Text Color</title>
</head>
<body>
   <h2 style="color: Fuchsia;">
       Setting Text Color in HTML
   </h3>
   <p style="color: Teal;">
       This line is created using paragraph tag 
       and its color is <b>Teal</b>. </p>
   <p style="color: SlateBlue;">
       This is another line created using paragraph
       tag and its color is <b>SlateBlue</b>. 
   </p>
</body>
</html>

Setting Background Color

To set the background color for any HTML element, we specify the color value inside the CSS background-color property.

<!DOCTYPE html>
<html>
<head>
    <title>Setting Background Color</title>
</head>
<body>
    <h2 style="background-color: Fuchsia;">
        Setting Background Color in HTML
    </h2>
    <p style="background-color: Teal; padding: 5px;">
        This line is created using paragraph tag
        and its background color is <b>Teal</b>.
    </p>
    <p style="background-color: SlateBlue;">
        This is another line created using paragraph 
        tag and its background color is <b>SlateBlue</b>.
    </p>
</body>
</html>

Setting Border Color

To set the border color for any HTML element, we can use the CSS border property or CSS border-color property.

<!DOCTYPE html>
<html>
<head>
    <title>Setting Border Color</title>
</head>
<body>
    <h2 style="border: 2.5px solid Fuchsia;">
        Setting Border Color in HTML</h2>
    <p style="border: 2.5px dotted Teal; padding: 5px;">
        This line is created using paragraph 
        tag and its border color is <b>Teal</b>.
    </p>
    <p style="border: 2.5px dashed SlateBlue; padding: 5px;">
        This is another line created using paragraph
        tag and its border color is <b>SlateBlue</b>.
    </p>
</body>
</html>
