Unable to remove blank space in simple HTML webpage

The problem isn't in your CSS, it's the new line after you close the </code> part. If you remove it, the space will disappear. This happens because text in a pre element is displayed in a fixed-width font, and it preserves both spaces and line breaks.

The space is caused by the </code> & </pre> tags if you remove the space from tags like this it should work </code></pre>.

Your code is reading the html as it is. Html does not read spaces however in your code it is.

You need to reset the natural padding and margin of the body and ol. Set:

body{
    margin: 0;
    padding: 0;
}

.header-left ol{
    width: auto;
    float: left;
    display: block;
    background-color: #6899D3;        
    margin: 0; //RESET DEFAULT
    padding: 0; // RESET DEFAULT
}

Add padding-left:0; to your .header-left ol rules.

.header-left ol {
    width: auto;
    float: left;
    display: block;
    background-color: #6899D3;
    padding-left:0;
}

Handling whitespace - CSS | MDN

The following JavaScript code shows several functions that deal with whitespace in the DOM: ... /** * Throughout, whitespace is defined as one of the characters * "\t" TAB \u0009 * "\n" LF \u000A * "\r" CR \u000D * " " SPC \u0020 * * This does not use JavaScript's "\s" because that includes non-breaking * spaces (and also some other characters).

element.text().replace(/\s+/g, " ");

This uses a regular expression (/.../) to search for one or more (+) whitespace characters (\s) throughout the element's text (g, the global modifier, which finds all matches rather than stopping after the first match) and replace each with one space (" ").

For the string

"    this  is my   string       "

You probably want to make the excessive spaces single spaces, but remove the leading and trailing spaces entirely. For that, add another .replace

s.replace(/\s+/g, " ").replace(/^\s|\s$/g, "");

For

"this is my string"

Update

s.replace(/\s+/g, " ").trim()

You must remove the margin on body:

body {
    padding:0;
    margin:0;
}

You can also remove padding and margin on html and body

html, body {
    padding:0;
    margin:0;
}

See it on jsfiddle

But I would not advise to use * (the universal selector)

* {
    margin: 0px;
    padding: 0px;
}

This would remove padding and margins on all elements.

The good method is to always use at the begining of the file (I forgot to metion this):

*{
    margin: 0px;
    padding: 0px;
}

This two line's at the begining of main CSS file fix many problem's that you can encounter. Hope it'll help you.
