Function sauron::html::attributes::styles_flag

pub fn styles_flag<MSG>(
    trio: impl IntoIterator<Item = (impl ToString, impl Into<Value>, bool)>
) -> Attribute<&'static str, &'static str, AttributeValue<MSG>>

A helper function which creates a style attribute by assembling only the parts that passed the boolean flag.

Examples

use sauron::prelude::*;

let is_active = true;
let display:Attribute<()> = styles_flag([
        ("display", "block", is_active),
        ("display", "none", !is_active),
    ]);

This could also be written as

use sauron::prelude::*;

let is_active = true;
let display:Attribute<()> =
    styles([("display", if is_active { "block" }else{ "none" })]);
