Indentation for Lists in html

An writing some html instructions to have text beside an image. The image
is located on the left and I want the tect to appear on the right side of the image.

The text includes a list. The problem is that the list boxes and not shifted.
The text within the list align on the left with the paragraph above. Usually when
doing <ul> after a paragraph, the list gets indented.

<h2>
  GNU Behistun <span style="font-size: 55%">Un insieme di
  software per la Tomografia Sismica</span>
</h2>

<img src="gbehistun--logo.png" style="float:left;margin:0
  34px 34px 0; height:18em;" alt="Logo di GBehistun"
  class="left"/> 

  <p>
  Una tecnica per la mappatura del sottosuolo (terrestre o
  stellare) che usa le onde sismiche prodotte dai terremoti,
  le vibrazioni antropogeniche e il movimento di fondo; la
  tomografia comporta tre processi fondamentali:</p>

  <ul>
  <li>La elaborazione numerica preliminare dell'
    informazione (es. metadati, dei segnali e della forma
    d'onda), adatte per la ricostruzione della propriet�
    fisiche subsuperficiali.</li>
  <li>La simulazione della propagazione delle onde
    sismiche.</li>
  <li>La determinazione delle propriet� interne usando
    algoritmi di stima e ricostruzione.</li>
  </ul>

You should put the <ul> element outside the <p> elements, <ul> counts as its own block.

I still have the problem. The problem happens when I am using the image on the left side.
In normal text, it is being indented as normal.

Try using a border-less table and put each elements in cells:-

<table border=0 cellspacing=2 cellpadding=2>
 <tr>

  <td>
   <img scr ...
  </td>
  
  <td>
   <p> ...
   <ul> ...
  </td>

 </tr>
</table>

How can I remove the table line enclosures?

What do you mean by table line enclosures? Are you referring to table border?

If yes, setting border attribute value to 0 will make it invisible. You can also remove below attributes:-

cellspacing=2 cellpadding=2

I meant that I want to remove a thin black line that displays two boxes

There should be no line if you set border to 0. Post your code.

<h2>
  GNU Behistun <span style="font-size: 55%">Un insieme di
  software per la Tomografia Sismica</span>
</h2>

<table border=0 cellspacing=1 cellpadding=1>
 <tr>

  <td>
    <img src="gbehistun--logo.png"
      style="float:left; margin:0 1cm 1cm 0; height:8cm;"
      alt="Logo di GBehistun" />
  </td>

  <td>
    <p>

Here is what I see when I open your code in Internet Explorer

I don't see a thin black line!

That's what I am trying to do, put for some reason, the box is still being displayed

Can you post the screenshot of your output?

Try HTML5:-

<table style="border:0" >

I have done the change but it boxes are still showing up.

That is strange, do you have a CSS that might be overriding it?

What should I look for?

If you have chrome browser:-

• Select the Chrome Menu at the top-right of your browser window
• Select More tools > Developer Tools
• Right-click on line and select Inspect Element

and check which one defines the border.

th, td {
border: 1px solid #bbb;
padding: .5em;
}

Looks like it is related to th or td

When I tick out border, the border is removed

There you go, that is the CSS overriding the attribute.
