Let’s walk through adding one component — a navigation bar — step-by-step so you understand how to use Bootstrap. You’ll then add the following line of code in the index.html file. This time, you’ll add it to the footer, instead of the header, right after the tag. If you plan to use the JS part as well, then you need to add two more lines of code. Components including alerts, toggle buttons, carousels, and dropdowns require the use of JavaScript to function so continue these steps if you want to add any of these elements to your site. Simply add the following line of code into the header of the index.html file, right before the tag.
- This would in some theoretical aspects be cleaner (independent subsets) but reduces the sample size (from 100 to 10) so much as to be impractical (in most cases).
- To avoid this issue, make sure to only add the classes you need and use the minified version of the files.
- Just add the .img-responsive class to your images, and the predefined CSS rules take care of the rest.
- You may consider all subsets of size 98 instead and get JK-2 (2 elements deleted) or JK-3 etc.
It speeds up the development process hugely, while still maintaining the level of quality and consistency that every programmer strives for. When Bootstrap is used, developers don’t need to re-design specific elements to fit the needs across browsers, devices, or platforms or spend hours and hours trying to figure out where a mistake is present. Most of the hard work isn’t handled by developers anymore, but by Bootstrap itself.
Why You Shouldn’t Use Bootstrap
In computing, the term bootstrap means to boot or to load a program into a computer using a much smaller initial program to load in the desired program, which is usually an OS. Mark Otto and Jacob Thornton developed Bootstrap at Twitter to improve the consistency of tools used on the site and to reduce maintenance. The software was formerly known as Twitter Blueprint and is sometimes referred to as Twitter Bootstrap.
When calculating a statistic of interest, bootstrapping can generate thousands of simulated samples that each feature their own statistic of interest. Teams can then develop a confidence interval that is more precise since it relies on a larger collection of samples as opposed to just one sample or a few samples. Imagine you’ve got a random sample of 9 measurements from some population. Can we be sure that the average of the whole population is also 60? Obviously not because small samples will vary, so the estimate of 60 is likely to be inaccurate. To find out how much samples like this will vary, we can run some experiments – using a method called bootstrapping.
Why is Bootstrap the go-to for web developers?

Most customers define specific bootstrap keys for different production batches. This way any manufacturer of the devices can use a specific bootstrap key to provision the full batch.
