What is the best way to use CSS to ensure that dynamic, data-driven characters can be properly displayed within a div

I'm in the process of updating a data-centric website that relies on information from an automated database engine. In the HTML, there's a fixed-size button containing text pulled from the database. I'm looking to incorporate some CSS styles to ensure the font always fits neatly within the button.

Below is the code snippet:

CSS:

.button { 
    width: 216px; 
    height: 44px; 
    background-color: 00baf2; 
    color: #fff;
    border-radius: 5px;
    font-size: 23px;
    line-height: 45px;
    font-weight: 500;
    text-align: center;

@media screen and (max-width : 768px) {
    .button { 
        width: 400px;
        height: 81px;
        font-size: 30px;
        line-height: 40px;
        background-size: 400px 81px !important;
        float: none !important;
        clear: both;
        margin: 25px auto; 
    }

HTML

<div class="button">View Your Plan</div> (static/not data-driven)
<div class="button">Current Members Click Here</div> (data-driven)
<div class="button">Enroll Now</div> (static/not data-driven)

The second/middle button is data driven, with varying lengths between "Current Members Click Here" and "See Your Plan Discount Program Here". If I remove the font-size and line-height, it defaults to small text. How can I make sure the dynamic text always fits inside the div button, regardless of length? Is this achievable through CSS alone or would a JS solution be necessary?

Answer №1

UPDATE:

I recently came across a suggestion to adjust the font size of the data-driven button to be smaller compared to the others. This can easily be done by specifying a smaller vw unit in the font-size property of the class assigned to that particular button.

Utilizing VW units makes it feasible, however, it is important to ensure a fallback for older browser compatibility. While I am not certain if this may cause issues on larger desktop screens, I hope it gives you insight into implementing this technique.

  .button {
    width: 216px;
    min-height: 44px;
    background-color: #00baf2;
    color: #fff;
    border-radius: 5px;
    font-size: 23px;
    font-size: 2vw;
    font-weight: 500;
    text-align: center;
    line-height: 44px;
  }
  .button.data-driven {
    line-height: 22px;
  }
  @media (max-width: 992px) and (min-width: 768px) {
    .button {
      font-size: 23px;
      font-size: 2vw;
    }
    .button.data-driven {
      line-height: initial;
    }
  }
  @media screen and (max-width: 768px) {
    .button {
      width: 400px;
      height: 81px;
      font-size: 30px;
      line-height: 81px;
      background-size: 400px 81px !important;
      float: none !important;
      clear: both;
      margin: 25px auto;
      padding-top: 0;
    }
    .button.data-driven {
      line-height: 81px;
    }
  }
<div class="button">View Your Plan</div>(static/not data-driven)
<div class="button data-driven">Current Members Click Here</div>(data-driven)
<div class="button">Enroll Now</div>(static/not data-driven)

Answer №2

To achieve a dynamic font size that adjusts to fit, CSS alone will not suffice. However, you can conditionally apply different classes to control the font size. For example:

.button.small-text {
    font-size: 12px;
}
.button.medium-text {
    font-size: 18px;
}
.button.large-text {
    font-size: 23px;
}

These classes would need to be adjusted within your media queries to accommodate varying button widths.

Subsequently, you can utilize backend or frontend scripting to add either small-text, medium-text, or large-text to your buttons.

If using jQuery, the process could resemble the following:

$('.button').removeClass('small-text medium-text large-text');
$('.button').each(function() {
    var length = $(this).text().length;
    if (length < 20) {
        $(this).addClass('large-text');
    } else if (length < 40) {
        $(this).addClass('medium-text');
    } else {
        $(this).addClass('small-text');
    }
});

Answer №3

To create a dynamic button, simply remove the height property and add display:inline-block to the button class. This will allow the button to adjust its size based on the text within it.

If you prefer a fixed height for the button, consider using a percentage value for the font-size property. For example, set font-size:10%;. The use of percentages allows for a relative sizing approach, maintaining consistency across different screen sizes.
