Responsive design allows users to benefit from the web page without having to worry about screen size and resolution. The aim of this study is to investigate the effect of responsive design on usability. For this purpose, a questionnaire consisting of a five-point Likert was applied to university students. According to the results, it was seen that 99.2% of university students had smart phones and used smart phones to connect to internet with a rate of 91.3%. It was observed that the participants' attitudes towards responsive design did not differ according to gender, and students in the 24–26 age group had more desire to use responsive design. And, university students' attitudes towards responsive design did not differ according to the Internet access method. It was found that 38% of the participants had a daily internet usage rate of 4–5 h and they used social media the most. Ease of use has been identified as the most preferred feature (Avg = 3.67/5, 73.4%) of usability in responsive design by evaluating dimensions central tendency measures. With regression analysis, responsive design explains 74.7% of the change in effectiveness (R² = 0.747) among the usability dimensions. With regression analysis, 91.5% of usability can be explained with the responsive design (R² = 0.915). Usability and responsive design (r = 0.92, p < 0.01) were both found to be positively correlated. It can be said that the academic university websites developed with responsive design are preferred by university students in the pandemic and this has increased usability and effectiveness.

响应式设计使用户可以从网页中受益，而不必担心屏幕尺寸和分辨率。本研究的目的是调查响应式设计对可用性的影响。为此，对大学生进行了由李克特五点组成的问卷调查。结果显示，99.2%的大学生拥有智能手机，使用智能手机上网的比例为91.3%。据观察，参与者对响应式设计的态度没有因性别而异，24-26 岁年龄段的学生更愿意使用响应式设计。而且，大学生对响应式设计的态度并没有因互联网访问方式而异。结果发现，38% 的参与者每天使用互联网的时间为 4-5 小时，他们使用社交媒体的次数最多。通过评估维度集中趋势度量，易用性已被确定为响应式设计中可用性的最优选特征（平均 = 3.67/5，73.4%）。通过回归分析，响应式设计解释了 74.7% 的有效性变化（R²  = 0.747）在可用性维度中。通过回归分析，91.5% 的可用性可以用响应式设计来解释（R ²  = 0.915）。可用性和响应式设计（r = 0.92，p  < 0.01）都被发现是正相关的。可以说，响应式设计开发的学术型大学网站在疫情期间受到了大学生的青睐，这增加了可用性和有效性。
