When needing to add a tab space between two words or sentences, my go-to options are

  and  

If the dimensions of the area exceed a certain limit, I typically opt for the following solutions:

For creating horizontal space:

<span style="display:inline-block; width: YOURWIDTH;"></span>

When it comes to vertical spacing:

<span style="display:block; height: YOURHEIGHT;"></span>

To represent spaces, use  , for the symbol < (less than) use < with entity number <, and for the symbol > (greater than) use > with entity number >.

Give   a shot.

According to the details provided in Special Characters:

The characters   and   represent an en space and an em space correspondingly. An en space is half the point size, while an em space equals the point size of the current font. In the case of fixed pitch fonts, the en space may be considered as equivalent to one space character, and the em space may be viewed as equal to two space characters.

Various Kinds of Spaces in HTML

To insert four spaces between text, use -  

For two spaces between text, utilize -  

To create a regular space between text, employ -  

To generate a narrow space (similar to regular space with slight variation), try using "&thinsp";

To specify spacing between sentences, consider using - "</br>"

I prefer using this method:

When styling with CSS:

.box { 
       display:flex; 
       justify-content: center; 
}

In your HTML code:

<div>Some Content <span class="box">Centered Text</span></div>

<p style="text-indent: 5em;">
The initial line of this paragraph will be shifted over by approximately five characters, akin to a tabbed indent.
</p>

The first line of this paragraph will be indented about five characters, similar to a tabbed indent.

Take it a step further from @Ivar and customize my own tag as follows... I find 'tab' easier to recall and use.

tab {
    display: inline-block;
    margin-left: 40px;
}

Now let's implement this in HTML...

<p>Left side of the whitespace<tab>Right side of the whitespace</p>

Here is my screenshot for reference...

<span style="margin-left:50px;"></span>

Another option is to utilize:

margin-left
margin-right
margin-top
margin-bottom

Also known as a fixed space or unbreakable space, non-breaking space (NBSP) is utilized in coding and document editing to insert a space in a line that cannot be split by automatic word wrapping.

In HTML, using   allows you to generate multiple spaces that are visible on a webpage rather than just in the underlying source code.

To create spacing, consider using padding such as

<span style="padding-left: 20px;">

Utilize the standard CSS property tab-size. For more information on browser compatibility, check out this link

To insert a tab symbol (to move the cursor as with the standard tab key), press Alt + 0 + 0 + 9

.element {
    -moz-tab-size: 4;
    tab-size: 4;
}

My preference:

*{-moz-tab-size: 1; tab-size: 1;}

Take a look at the snippet or find a quick example here.

.t1{
    -moz-tab-size: 1;
    tab-size: 1;
}
.t2{
    -moz-tab-size: 2;
    tab-size: 2;
}
.t4{
    -moz-tab-size: 4;
    tab-size: 4;
}
pre {border: 1px dotted;}

<h3>tab = {default} space</h3>
<pre>
    one tab text
        two tab text
</pre>

<h3>tab = 1 space</h3>
<pre class="t1">
    one tab text
        two tab text
</pre>

<h3>tab = 2 space</h3>
<pre class="t2">
    one tab text
        two tab text
</pre>

<h3>tab = 4 space</h3>
<pre class="t4">
    one tab text
        two tab text
</pre>

For those seeking a way to arrange items in line, consider utilizing the <table> element.

Place each item within a <tr> ... </tr> tag and each element inside that row within a <td> ... </td> tag. You can adjust the padding of each cell to control the spacing between them.

By using this method, your items will be neatly aligned and visually appealing :)

Here is the solution that worked best for me:

I've defined my tabs in the CSS like this:

tab0  { position:absolute;left:25px;  }
tab1  { position:absolute;left:50px;  }
tab2  { position:absolute;left:75px;  }
tab3  { position:absolute;left:100px; }
tab4  { position:absolute;left:125px; }
tab5  { position:absolute;left:150px; }
tab6  { position:absolute;left:175px; }
tab7  { position:absolute;left:200px; }
tab8  { position:absolute;left:225px; }
tab9  { position:absolute;left:250px; }
tab10 { position:absolute;left:275px; }

Then, I can simply use these tabs in my HTML content like so:

Dog Food <tab3> :$30
Milk <tab3> :$3
Pizza Kit <tab3> :$5
Mt Dew <tab3> :$1.75

User92840123's solution works best for aligning content across multiple lines. Despite encountering issues with the provided code example, a slight modification was necessary:

<html>
    <head>
        <style>
            .tab9 {position:absolute;left:150px; }
        </style>
    </head>

    <body>
        Dog Treats: <span class="tab9"> $20</span><br/>
        Catnip:<span class="tab9"> $15</span><br/>
        Fish Food:<span class="tab9"> $8</span><br/>
        Bird Seed <span class="tab9"> $3.50</span><br/>
    </body>
</html>

To right-align numbers, simply replace left:150px with right:150px. But remember to adjust the number value according to the screen width (the current setting positions the numbers 150 pixels from the right edge of the screen).

Having some extra space in your design is essential, right? Instead of white space, why not utilize padding for a similar effect? This CSS snippet shows you how to add that desired "blank area" around your element:

padding: 10px;
padding-top: 10px;
padding-bottom: 10px;
padding-left: 10px;
padding-right: 10px;

If you need to create space in your HTML content, simply use the code  . To add a tab space, repeat the code at least 5 times.

For an example, visit this link: https://www.w3schools.com/charsets/tryit.asp?deci=8287&ent=ThickSpace

When faced with a similar issue, I found that inserting at the start of every paragraph was necessary. To achieve this, I implemented the code below which successfully resolved the problem for me. Hopefully, it proves useful to others facing the same challenge.

p:first-letter {
    padding-left: 15px;
}

In the realm of HTML, the character entity known as 	 symbolizes the horizontal tab space. Much like hitting the tab key on your keyboard, this feature comes in handy for enhancing text and code alignment within HTML documents.

If you want to see this tab character visibly displayed, ensure that it is enclosed within an element styled with white-space: pre; – just like any other form of whitespace. Another method is to utilize the

<pre>&#9; text</pre>

Here's an illustrative example:

<p style="white-space: pre;">
Text aligned&#9;&#9;&#9;&#9;with a tab space.
more text&#9;&#9;&#9;&#9;aligned
</p>
