Maximizing the efficiency of critical rendering path while utilizing bootstrap

Is it feasible to enhance the critical rendering path (like Google and Facebook) while utilizing Bootstrap 3?

Facebook opted for inlining styles connected to the header and sidebars. Meanwhile, Google inlined all styles since they have minimal styles for their homepage.

The challenge lies in wanting to inline header-related styles, which would include over 10 classes from Bootstrap such as container-fluid, row, col-lg-10, col-lg-offset-2, etc. Inlining Bootstrap is not ideal due to its large file size of over 100kb.

I aim to load above-the-fold content swiftly.

Is there a strategic approach to achieve this? Any suggestions?

Answer №1

This method can be implemented regardless of the framework you are using, even if it's not Bootstrap. You need to find a way to identify your critical CSS and then embed it directly into your HTML file. There are various approaches to achieve this:

Before jumping into in-line styles, it's important to consider other optimizations that can be implemented first. Using in-line styles could result in duplicated styles in the HTTP request, which may impact performance and create a maintenance nightmare.

  1. Make sure to load CSS in the head section of your HTML document.
  2. Load JavaScript at the end of the body to ensure faster page rendering.
  3. Customize Bootstrap by including only the necessary styles using the customization tool available at http://getbootstrap.com/customize/.
  4. Bundle and minimize header-related files separately to take advantage of caching and minification. Consider segregating Bootstrap components for better organization.
  5. For single-page applications, optimize the initial load page and use modules/web components to ajax in templates as needed.
  6. Utilize CDNs to maximize the number of HTTP connections per host.

Answer №3

In terms of optimizing performance, it is generally not necessary to add extra inline code. The best approach to reducing loading time is to customize your bootstrap by removing unnecessary classes and minimizing and gzipping the file before transmission. Most often, you will not require the full 100kb of bootstrap CSS.

It's important to note that rendering elements in the browser is typically more resource-intensive than applying classes. While you can improve load times to a certain extent, there are limits to optimization.

If you require extremely fast loading times for specific components, such as headers, then using inline code may be necessary. However, the necessity of this approach depends on the performance requirements of your project.
