Why Does This Happen?

JavaScript was created with the idea to add interactivity to the HTML pages.
JavaScript gives HTML designers a strong but convenient programming tool. Although the majority of HTML designers have nothing to do with real programming, JavaScript simplified their job even more because it is a scripting language with very simple syntax.

About 57% of sites are using custom fonts now. In 2017 an average site’s fonts take about 113kb of the general dimension, when in 2010, this number was only 2kb. The font is an important thing for personal branding. However, it also has an impact on the site’s dimension and therefore, you need to choose a font that will not only fit the style of your site but also be quickly loaded.

Over the last six years, the dimension of an average video has grown to 174kb and although it still takes only 7.7% of a medium total website size, soon it will become another big issue.



In the modern world, the ads have become more complex. They are no longer made of only plain text. To get the most attention, usually, SMM add photos, animations or even videos to their advertisings and naturally, this increases the site’s speed of loading and dimension. How to avoid this?
