Markdown Tips

In Markdown, setting the size of an image directly within the syntax can be a bit limited because standard Markdown doesn't support inline styling or classes directly. However, you have a few options depending on your setup and how you're processing Markdown in your Next.js blog, especially if you're using extensions like remark or mdx which can enhance Markdown capabilities. Here are some common methods:

1. HTML within Markdown

The simplest and most universally compatible way to set the size of an image in Markdown is by using raw HTML. Most Markdown processors, including those used in static site generators like Next.js, allow HTML code within Markdown files.

<img src="path/to/image.jpg" alt="Description" width="500" height="300" />

You can replace 500 and 300 with whatever dimensions you prefer. This method is straightforward and works well if you don't need to resize images dynamically based on the viewport.

2. Using Markdown Extensions (like MDX)

If you're using MDX (Markdown for JSX), which allows you to use JSX within Markdown, you can directly apply inline styles or className to images like so:

<img src="path/to/image.jpg" alt="Description" style={{ width: "500px", height: "auto" }} />

or using classes defined in your CSS:

/* styles.css */
.responsive-image {
    width: 100%;
    height: auto;
    max-width: 500px; /* adjust max-width as necessary */
}

<img src="path/to/image.jpg" alt="Description" className="responsive-image" />

3. Using CSS for All Images

If you prefer all images in your Markdown content to follow a specific sizing rule, you can use CSS to control their dimensions universally. This is particularly useful if you don't want to manually set sizes for every image. You would typically do this in your global stylesheet:

img {
    width: 100%;
    height: auto;
    max-width: 500px;
}

This CSS ensures that all images are responsive, filling the width of their container up to a maximum width of 500 pixels.

4. Tailwind CSS Utility Classes

Since you are using TailwindCSS, you can apply utility classes to images if you are processing your Markdown to support such features, which MDX does allow:

![Description](path/to/image.jpg){:class="w-full md:w-1/2"}

Note: The syntax {:class="..."} might not work out of the box depending on your Markdown processor configuration. You may need additional plugins like remark-attr.

5. Plugin-Based Resizing (Remark & Rehype)

If you are using remark and rehype plugins to process Markdown, you can find or configure plugins to resize images based on the Markdown syntax or metadata. For instance, rehype-img-size plugin can be used in your processing pipeline to automatically set image sizes based on file attributes.
