title: indentation:Only use indent of 4 spaces in vscode
body: <p>Every time I open *.sol file in VSCode that already exists in the project it shows <code>indentation: Only use indent of 4 spaces</code> error even though <strong>I'm using 4 spaces for indentation, but get a Syntax error.</strong> Every time I have to clear that 4 space and again create 4 space for remove error.</p>
  
  <p>I already have gone through the similar questions in stack overflow but didn't get approved answer. One of the related question is <a href="https://stackoverflow.com/questions/39070917/4-spaces-for-indentation-syntax-error">this</a> .</p>

  <p><strong>Note :</strong> I used .sol extension of vs code for compile the code.</p>
