Repository: DavidVujic/python-hiccup

Issue:
Content (inner text) should be placed in the correct order
**Describe the bug**
Content is placed after any child elements of a html element. It should be able to use the position in the hiccup sequence.

**To Reproduce**
This test will fail:
```python
def test_order_of_items() -> None:
    """Assert that items of different types are ordered as expected."""
    data = ["h1", "some", ["span.pys", "<py>"], "jokes"]

    assert render(data) == '<h1>some<span class="pys">&lt;py&gt;</span>jokes</h1>'
```

The rendered output is 
```html
<h1><span class="pys">&lt;py&gt;</span>somejokes</h1>
```

**Expected behavior**
It should be possible to specify the content to be before any child elements.

 This is a Python implementation of the Hiccup syntax. Python Hiccup is a library for representing HTML in Python.
 Using `list` or `tuple` to represent HTML elements, and `dict` to represent the element attributes.
 
+_This project started out as a fun coding challenge, and now evolving into something useful for Python Dev teams._
+
 ## Usage
 Create server side HTML using plain Python data structures.
 This library should also be possible to combine with PyScript, but I haven't tested that out yet.
