Looking to adjust line-height property for text with different line heights

I am struggling with adjusting the line-height of row-based text content in HTML enclosed in <p> tags. The challenge I'm facing is that the text could vary in length, resulting in either one or two lines. If it's a single line, it should contain up to 30 words. I believe this can be achieved using JavaScript or jQuery with an if statement, but being a beginner in these languages, I need guidance on writing the necessary code with complete syntax instead of just snippets.

I also need assistance in understanding where to place the syntax - whether inside the head section or at the bottom in the body - as the placement can impact the functionality.

Update:

I have included a link for reference - . Please let me know if more details are required. Thank you!

Update:

A working example is available at - http://jsfiddle.net/ravk/M4GSR/.

Based on the fiddle, my goal is to dynamically set the line-height based on whether the text spans one or two lines (not more than two). Additionally, I aim to vertically center the text within the base div.

Answer №1

A method to achieve this is by utilizing JAVASCRIPT

insert the following snippet:

   <body>
      <p id = 'p'> // your text </p>
    </body>
      <script type = 'text/javascript'>
         p = document.getElementsByClassName('txt-mid')
         for(i in p){   
          no_of_words = p[i].innerHTML.length
          alert(no_of_words)
           if(no_of_words <= 30){
             p[i].style.lineHeight = '100px'
           }
          else{
            p[i].style.lineHeight = '50px'
          }
            }
      </script>
