Flexible CSS rule-sets to keep your images within their parent element

Since an image is worth a thousand words, we use images in your webpage to express complex ideas succinctly.

By default, if we do not specify any dimensions for an image, most browsers will show the image according to its actual size. In this situation, an image will appear to spill over the boundaries of its parent element if it is bigger.

For example, the following screenshot shows the image at https://commons.wikimedia.org/wiki/File:LARGE_elevation.jpg spilling over its parent element:

Example of large image overspilling the parent container

One way to prevent a larger image from going beyond the boundaries of its parent element is to give a standard width to all images. However, if the actual width of an image is smaller than the given width, the image will be stretched:

Implementing Google Custom Search as a WordPress page without using any plugin

Creating a search engine to search content across a polyglot website is not an easy task. In order to do that, you need to either:

  • have a process that will maintain an index of content from the different applications and search within that content.

Since Google had indexed most of the content in the Internet, Google Custom Search can be the easiest way for us to implement site-wide search. In addition to fast searching, Google Custom Search also comes with AdSense monetization.

In case you need it, this is how you can implement Google Custom Search as a WordPress page without using any plugin.
