How do I take advantage of colours in HTML?

Let’s paint the city crimson. Effectively, not the city, per se. Let’s begin with the background of an HTML electronic mail template.

Right here’s a easy HTML code that units the HTML background shade to crimson:

<physique type="background-color:crimson;">INSERT CONTENT HERE.</physique>

Right here, we used an HTML shade title, “crimson,” to specify the background-color.

There are just a few methods to refer to colours in HTML, together with:

1. HTML shade title
2. Hex shade code
3. RGB worth
4. HSL worth

Try this shade picker for the assorted HTML shade codes, and let’s dive into every of those in additional element beneath.

1. HTML shade title

The HTML shade title might be probably the most intuitive option to specify a shade in HTML. Within the earlier code pattern, you merely use the HTML shade title to specify the colour in your background. Try W3C’s useful record of HTML shade names.

2. Hex shade code

Hex shade codes encompass a hashtag “#” adopted by a sequence of six letters and/or numbers. For instance, the Hex shade code for crimson is #FF0000. You’ll be able to set your background-color to crimson through Hex shade code with the next code:

<physique type="background-color:#FF0000;">INSERT CONTENT HERE.</physique>

3. RGB worth

RGB refers to crimson, inexperienced, and blue. These three colours of sunshine combine to create all different colours, together with white. Utilizing RGB, you may specify a shade with three numeric values, starting from 0 to 255, and representing the values for crimson, inexperienced, and blue. By assigning values to rgb (crimson worth, inexperienced worth, blue worth, alpha worth) to seek out your required shade. Right here’s the pattern code utilizing RGB values to set your background-color as crimson:

<physique type="background-color:rgb(255,0,0);">INSERT CONTENT HERE.</physique>

On this instance, the primary worth (crimson) is 255, which is the utmost worth, and the following shade values for inexperienced and blue to 0. These values combine, producing the colour crimson.

RBGA provides one other worth to RBG to incorporate extra customization. The final worth, the alpha channel, permits you to specify the opacity of the colour. You’ll be able to write RBGA as rgb (crimson worth, inexperienced worth, blue worth, alpha worth). Purple, inexperienced, and blue take a price of 0 to 255 and alpha takes a price between 0 for absolutely clear to 1.0 for absolutely opaque. Try the next code, which is a half-transparent crimson background-color:

<physique type="background-color:rgb(255,0,0,0.5);">INSERT CONTENT HERE.</physique>

4. HSL worth

HSL, which stands for hue, saturation, and lightness, is one other set of values used to “combine” chosen colours. The syntax to specify HSL worth is much like that for RGB because it consists of three values. Try the pattern code to specify a crimson background utilizing HSL: First, a price from 0 to 255 specifies the hue. Then, a proportion from 0% to 100% signifies the saturation. Lastly, a proportion from 0% to 100% dictates the lightness.

<physique type="background-color:hsl(0,100%,50%);">INSERT CONTENT HERE.</physique>

Similar to with RGBA, HSL will be prolonged with an alpha channel that takes a price between 0 for absolutely clear to 1.0 for absolutely opaque. Try the instance beneath. The primary three values are the identical as within the instance above. The final parameter is a price between 0 and 1.0 that signifies the transparency of your shade.

<physique type="background-color:hsla(0,100%,50%,.5);">INSERT CONTENT HERE.</physique>
