Use special attributes to change the content on the page:

• if - hides or shows the element depending on the condition if="cond"

example: if="num > 5"

• on - adds listener events to the element on="event:your_code"

example: on="click:num++"

• in - is used to insert a variable into the text of an element <p in>{your_code}</p>

example: <p in>your name {userName}</p>

• css - used to style elements css="css_property:your_code"

example: css="color: isValid ? 'green' : 'red'"

• bind - use to bind some element value to a variable bind="element_property:your_code"

example: <input bind="value: userName>"

To change variables through a script, use the object that will return data()

<h1>
  color is:
  <span css="color:color" in>
    {color}
  </span>
</h1>

<script> 
  const dt = RemJs.data({ color:'red' })
    
  setTimeout(()=>{ dt.color = 'blue' }, 1000)
</script>
