              <div class="card-content">
                <p>I am a very simple card. I am good at containing small bits of information. I am convenient because I

This is what my main index.html file looks like? And how would i fix the issue for the future. Thank You

Answer 1

可以改变CSS

.card-image{ height: 300px; //or however you want it width:auto; //so that the image ratio stays the same }

Answer 2

In a separate CSS file to override materialize file, you can use a fixed height or a min-height.

<pre>
    .card-image {
       height: 465px;
    }

    // alternatively...

    .card-image {
       min-height: 465px;
    }
</pre>

Answer 3

Scale the images as background.

<div class="card-image" style="background-image: url('img/4.jpg');"></div>

In Css

.card-image {
  background-repeat: no-repeat;
  background-position: 50% 50%;
  background-size: cover;
  width: 300px;
  height: 300px;
}

Answer 4

我认为这里最简单的解决方案是在photoshop或任何其他类似程序中手动使所有图像大小相同。
