Text and HTML
A text’s elements can be changed by HTML code using opening and end tags. HTML has six levels of headings ranging from H1 to H6. H1 has the highest priority while H6 is the lowest. The heading range in size from large to small. There is also p where the text goes in its own space of text like a paragraph. There is also b to make the text bold and i to make it italic. The code br puts words in different brackets and hr separates text with a line. Citations, blockquotes, abbreviations, and many other text elements can change texts.
CSS and Color
CSS has an invisible box around every HTML element and allows the developer to create rules that control the way that each box’s content is presented visually. A developer can add a border around any box containing HTML content and specify its width, height, and background color. Text can also be controlled by color, size, and style.
HSL and HSLA
In older for older browsers to recognize HSL and HSLA values, one must add an extra rule that specifies the color using RGB value, color name, and hex code. This extra rule should appear before the rule that uses the HSLA and HSL values. HSL and HSLA color properties are hue, saturation, and lightness. Hue is express an angle between 0 and 360, while saturation is express as a percentage. Lightness is also expressed as a percentage with 0% being white, 50% being normal, and 100% being black.
