The html5tag package contains utilities to generate html 5 tags. Choose between string versions of the functions for easy tag creation, or io.Writer versions for speed.

html5tag also has a tag builder for convenience and can perform math operations on numeric style values.

html5tag does some checks to make sure tags are well-formed. For example, when adding data-* attributes, it will make sure the key used for the attribute does not violate html syntax rules.

html5tag has options to pretty-print tags and the content of tags so they appear formatted in a document. However, in certain contexts, like in inline text, or in a textarea tag, adding extra returns and spaces changes the look of the output. In these situations, use the functions that do not add spaces to the inner HTML of a tag.

Some examples:

package main
import . "github.com/goradd/html5tag"
main() {
	
	// Render an input tag, inside a div tag, inside a body tag using different tag building mechanisms
	a := NewAttributes().
	SetID("myText").
	Set("text", "Hi there").
	Set("placeholder", "Write here").
	SetClass("class1 class2").
	SetStyle("width":"20em")
	
	inputTag := RenderVoidTag("input", a)
	divTag := RenderTag("div", Attriubtes{"id":"inputWrapper"}, inputTag)
	
	bodyTag := NewTagBuilder().
		Tag("body").
		ID("bodyId").
		InnerHtml(divTag).
		String()
	
	fmt.Print(bodyTag)
}
