Sometimes, you might be in a situation where you have a web page showing one element above another as shown in the HTML code but you want the 2nd element to appear above the first element in the browser. One way to accomplish this using just CSS is by using flex, flex column, and order. Witness below. By changing the value of “order”, you can change the order the element appears in the browser.

The key is to use overflow: hidden on the paragraph text.

Wi-fi

Theoretical speeds

802.11b – 11 Mbps (2.4GHz)
802.11a – 54 Mbps (5 GHz)
802.11g – 54 Mbps (2.4GHz)
802.11n – 600 Mbps (2.4GHz and 5 GHz) – 150Mbps typical for network adapters, 300Mbps, 450Mbps, and 600Mbps speeds when bonding channels with some routers
802.11ac – 1300+Mbps (5 GHz) – newer standard that uses wider channels, QAM and spatial streams for higher throughput

Actual Average Speeds

Below is a breakdown of actual real-life average speeds you can expect from wireless routers within a reasonable distance, with low interference and small number of simultaneous clients:

802.11b – 2-3 Mbps downstream, up to 5-6 Mbps with some vendor-specific extensions.
802.11g – ~20 Mbps downstream
802.11n – 40-50 Mbps typical, varying greatly depending on configuration, whether it is mixed or N-only network, the number of bonded channels, etc. Specifying a channel, and using 40MHz channels can help achieve 70-80Mbps with some newer routers. Up to 100 Mbps achievable with more expensive commercial equipment with 8×8 arrays, gigabit ports, etc.
802.11ac – 70-100+ Mbps typical, higher speeds possible over short distances without many obstacles, with newer generation 802.11ac routers, and client adapters capable of multiple streams. Continue reading Computer and Networking Speeds
