Brief 02 What are the main technical issues in web design?

It is my first website design experience so before building my website I have to know what kind of thing should I take care of.

Colours

The first main difference between print and web design is the colours. Indeed I will work in RVB instead of CMJN. 
They are some tips to choose the good colours. First I have to think about my target audience, however I must avoid clichés to gain credibility. Then I need to avoid colours competitors, to eliminate them from my own color schemes.

Competitors_

Basically, I should avoid this colour scheme_

Resolution_

I found this this table that can be my guideline for my mediaqueries.

Screen width	Smallest screen height	In use worldwide  Source: W3C, Jan 2016
1024 px	768 px	3%
1280 px	800 px	11%
1360 px	768 px	2%
1366 px	768 px	35%
1440 px	900 px	6%
1600 px	900 px	6%
1680 px	1050 px	3%
1920 px	1080 px	20%
2560 px and up	1440 px	1%

However I chose to use the resolution of my own mac, to have a batter quality.

Typographies_

Web typographies rules: 

• A preference for sans serif font. In fact, after research, pretty much every big block of text is set in a sans serif typeface, making it much easier to read. Headlines and other smaller blocks of text are laid out in serifed fonts, creating a balance between the two.)
• Avoid the centered text can make a website design easy to read.
• Take care with type colours, The easiest fix for that is to make sure that the colour of my type is drastically different from that of my background.
• Type size: less than 12pt is not enough. Most, however, chose a larger size like 14px, which is even better for readability. Plus, readability in large titles is far easier to figure out than in body copy.
